DIY trunk with button for VAZ 2107

Benefits of this option

Many people do not find anything special in this option, but once you try the electric trunk drive, you immediately begin to appreciate all the advantages. The positive aspects of the option to automatically open the trunk on the VAZ-2107 include:

Convenience. By the time the driver leaves the cabin, the trunk will already be open.
Practicality. There is no need to remove the keys from the ignition switch to open the trunk with the key, especially if you have just started the engine and are warming it up.
Fashion. Almost all modern cars are equipped with such an interesting option, so the “seven” with this function will look more interesting against their background, especially with tuning.

Next, we’ll look at what the procedure for installing an electric drive for opening the trunk on a VAZ 2107 is with your own hands.

What is required for the work

Before starting the work process, you should purchase the necessary equipment. To carry out the work you will need:

A button that, when pressed, will activate the electric drive. The best option is a button from a VAZ-2110 car, the cost of which is about 50-80 rubles.
The relay is four-pin and has a special terminal for it.
Activator.
Wires.
Female and male connectors, as well as electrical tape and heat shrink.

You can easily find any of the components in any auto store, and then install and connect it to your car yourself.

Installation of the activator

Initially, it is necessary to install an activator, which is an electric drive that works to retract or repel, depending on the connection. The first step is to remove the lock and install the activator rod. To remove the lock, you will need to unscrew two nuts.

After this, you need to drill a hole in the side of the lock to insert the rod and connect it to the lock tongue. The rod will need to be bent (secured), it should look something like the one shown in the photo below.

After fixing the rod to the lock, the latter can be installed in place. It is advisable to remember the tilt level of the lock and install it as well, so that you do not have to adjust it during installation. Now you can attach the activator to the trunk. To do this, you will need 2 self-tapping screws and a special plate, which comes with the product. After this, you can manually try to see if the lock will work when opening. When the activator is installed on your VAZ 2107 car, you can proceed to the next stage - connection.

Connecting the product

Before carrying out connection work, be sure to disconnect the negative terminal from the battery. To begin with, we present the diagram according to which the product will function.

About the trunk lock of the VAZ 2107

The electric lock will be supplied with 12V power directly from the battery, although you can also use a wire from the cigarette lighter. First, connect the wire to the “+” terminal of the battery.

The battery supplies power to the relay, which can be located both in the cabin and in the engine compartment, which will be much more rational. From terminal “86” the wire is fed to the trunk opening button, which can be located in any convenient place on the dashboard. To install the button that will open the trunk lid, you will need to drill a hole of the appropriate diameter in the dashboard.

Replacing the trunk lock of a VAZ 2107

To remove the trunk lock, you must perform the following steps:

If you are only replacing the trunk lock cylinder of a VAZ 2107, then the removed lock must be cleaned and the parts lubricated with “Litol” or aerosol lubricant. If the old lock also needs to be replaced, then it is necessary to lubricate the parts of the new lock. Once the lock is lubricated, install it as follows:

insert the sealing ring of the lock into the trunk lid;
insert the lock cylinder into the drive extension (distance sleeve);
install the cylinder with the bushing into the lock;
install the lock assembly in its regular place on the trunk lid, focusing on the pencil marks;
secure the lock with two bolts and tighten them with a 10mm wrench.

If the lock does not close well, its position relative to the latch should be adjusted. To do this, you need to loosen the fastening bolts and change its position so that the latch fits freely into the body and the lever securely fixes it, and there is a uniform gap between the trunk lid and the body around the entire perimeter. To adjust the force of opening the trunk lid, you need to use a mounting tool to move the ends of the torsion bars of the springs to one of the teeth of the trunk hinges.

This completes the replacement of the VAZ 2107 trunk lock.

The trunk lock on a VAZ 2107, like any mechanism, tends to fail over time. As a result, the lid does not fix well and knocks during the trip. Replacement is not the only reason why you sometimes have to remove the lock. The key may be lost or the cylinder mechanism may break. Let's look at how to carry out repairs yourself without visiting a service station.

Roof rack VAZ 2107

If the “seven” is often used to transport various cargoes, then, as a rule, the standard trunk is not enough. In this case, it is convenient to use a special roof rack. Oversized cargo can be secured on this structure. Before choosing a product, you need to find out the dimensions of the elements that can be placed on the trunk. Long materials such as boards, sticks, pipes, if their length is up to 4.5 meters, may not be marked with red flags. If the cargo exceeds the dimensions of the vehicle, i.e. protrudes beyond the front and rear bumpers, it must be marked with special red flags that inform other road users about the transportation of oversized cargo.

What types of luggage racks are there?

On the roof of the VAZ 2107 you can install a roof rack of both the old type and the modern type. The standard “Zhigulevsky” trunk has dimensions of 1300*1050*215 mm, and its load capacity is up to 50 kg. This structure is fastened to the roof gutters using bolts. In general, roof racks can be divided into 3 groups:

The first option is universal. The product consists of transversely and longitudinally directed metal beams with a square or round profile.

The closed trunk is a trunk (box). The main advantage of this design is the protection of the transported cargo from bad weather.

The product, made in the form of racks, is used for transporting bicycles and other equipment. This design is used less frequently, but the load can be fixed on it easily and reliably.

Which manufacturer to choose

There are many manufacturers of roof racks for the VAZ 2107 on the Russian market. The most popular companies include: Mamont (Russia), Golitsyno (Russia), BelAZ (Belarus), Inter (Russia). The price range of products ranges from 640 rubles. up to 3200 rub.

How to install

Structurally, the roof of the “seven” has storm drains to which the trunk racks are attached. The installation of the structure for transporting luggage on the roof of the VAZ 2107 should be carried out at the same distance from the front and rear windows. Thus, the load on the upper part of the body and the pillars is distributed evenly. The rack fastenings are placed so that they do not create an obstacle to the doors when they open and close. On the Lada seventh model of recent years of production, there are special marks in the interior that indicate where the A-pillars are located. This makes it easier to install the product on the roof and position it.

Before tightening the racks, you need to make sure that they are parallel to each other without distortion. If an installation error occurs, the roof surface may be damaged. After installing the racks, tighten the fasteners tightly so that the rubber elements are pressed well against the roof gutters. Having secured the luggage structure to the body, the product is considered ready for use. The main thing is to ensure that the load is securely secured, which will prevent its loss during sudden braking or maneuvers.

All about the roof rack VAZ 2107

Cars of the VAZ “classic” family enjoy well-deserved love, including as economic “horses”. These cars carry trailers, building materials stick out of the windows, and, of course, every self-respecting summer resident has a special roof rack for transporting oversized and long cargo.

First of all, you need to decide on the dimensions of the VAZ 2107 trunk in order to know what maximum dimensions of cargo can be placed in the trunk with the lid closed. Here they are:

Everything that extends beyond these dimensions must be placed on the roof of the VAZ 2107 and transported on the top, removable trunk. This is especially true for long items. Materials such as boards, sticks, floor slats, if they do not exceed 4.5 meters in length, may not be marked with red marker flags. In the event that they protrude beyond the front and rear bumpers, they must bear the oversized load mark. This is especially true at the rear end.

There is an explanation for this: the front end is clearly visible to the driver, and he himself makes sure not to drive too close at the traffic lights.

The roof rack of the car is designed for a weight of no more than 50 kilograms. If the driver is sure that the road will be perfect, without the slightest holes, bumps and vertical vibrations, then you can put 75 and even in extreme cases 80-90 kg, but no more. Carrying heavier loads will cause deformation of the body structure, and this leads to disruption of the opening and closing of doors.

The photo shows an old trunk that was produced in the USSR. Its weak point is its “bowl-shaped” shape with raised edges. On such a trunk it is difficult to transport barrels placed on the roof, sheets of cellular polycarbonate rolled into cylinders due to the small number of points of contact.

Currently, all “classics” have high-strength and lightweight roof racks that fit all car models, from VAZ 2101 to VAZ 2107. They are made quite durable and lightweight, and are coated with anti-corrosion powder paints.

The supporting system itself, as a rule, is hollow box-shaped bars made of strong sheet metal, square in cross-section, which are located in a single row, in the amount of 6 - 8, connected at the ends by supports that give rigidity to the structure. Four support mechanisms, which have different designs, are attached to the supports. Most often they are made using eccentric - tightening screws.

In order not to scratch the profile of the VAZ 2107 drain, to which the trunk is attached, the contacting parts are equipped with inserts - polyethylene liners.

When installing a trunk on a VAZ 2107, you must follow two rules:

The edges of the trunk should be at an equal distance from the windshield and rear window - this ensures correct alignment and distribution of the load on the roof;
When tightening, you must maintain uniformity. There should be no unevenly tightened eccentrics;

It is even more important to follow the rules for securing cargo on the trunk.

The most important thing is that the loads are securely fastened in the anteroposterior direction

When the vehicle brakes in an emergency, heavy loads occur and cargo can be torn off the trunk. When driving with a loaded rack on roundabouts and long turns, you need to drive slower than usual and evenly, otherwise the angular acceleration may be too strong and the load will be torn to one side. When transporting long boards and whips, you must be very careful when starting, accelerating and braking, as the ends of the whips “play” and rock the car, causing vibration. Particular attention should be paid to transporting bulk cargo in strong winds - if possible, you should avoid this and wait for calm weather; Loads with a large area and resistance (rolled covering material, empty barrels) must be secured especially carefully; While driving, listen carefully to the sounds on the roof. Take the time to go out several times and check the reliability of the fastening of the cargo and the trunk itself.

By applying these simple rules, you can avoid troubles associated with a sudden drop and damage to the load, or - even worse - creating an emergency situation on the road.

Simple ways to open a VAZ

Now let's get down to the methods. Conventionally, they can be divided into two groups: radical - when actions are decisive and not always justified, and delicate - calmer, conservative methods:

Open the door with wire

As you understand, it is better to use delicate methods, since more decisive and drastic ones will lead to the fact that you will have to pay for repairs. For example, if you break the lock to your vehicle, you will have to order it along with new keys and wait a long time until the order is fulfilled. Thus, you will not be able to use the car. Well, having broken the glass, you will have to install a new one.

Let's look at delicate methods

Method 1: Open the trunk

To open the trunk of a VAZ, you will need:

Using an open palm, strike the area below the trunk lock. The blow must be strong and sharp enough.
Take an awl (if it’s not there, then buy a nail file at the nearest stall, and you don’t have to open the trunk).
Using an awl or nail file, try to get under the door seal and press the tongue.
The door is open!

Method 2: Open the hood

You will have to crawl under the car to get the lanyard connected to the hood latch. If you can't find it, try to find it through the radiator mesh.
Mechanically press the tongue or simply pull the cable, the hood will open.
On the car battery, find the terminals with the “minus” value, click them on the mount a couple of times.
Since the body has a “minus” value, disconnecting it with the terminal will cause the doors to unlock.

Benefits of this option

Convenience. By the time the driver leaves the cabin, the trunk will already be open.
Practicality. There is no need to remove the keys from the ignition switch to open the trunk with the key, especially if you have just started the engine and are warming it up.
Fashion. Almost all modern cars are equipped with such an interesting option, so the “seven” with this function will look more interesting against their background, especially with tuning.

Next, we’ll look at what the procedure for installing an electric drive for opening the trunk on a VAZ 2107 is with your own hands.

How to install an electric trunk?

What is required for the work

Before starting the work process, you should purchase the necessary equipment. To carry out the work you will need:

A button that, when pressed, will activate the electric drive. The best option is a button from a VAZ-2110 car, the cost of which is about 50-80 rubles.
The relay is four-pin and has a special terminal for it.
Activator.
Wires.
Female and male connectors, as well as electrical tape and heat shrink.

You can easily find any of the components in any auto store, and then install and connect it to your car yourself.

Installation of the activator

Connecting the product

Before carrying out connection work, be sure to disconnect the negative terminal from the battery. To begin with, we present the diagram according to which the product will function.

The wire from the relay terminal “30” is laid through the cabin to the activator. Its length must be at least 5 meters. The wire can be laid together with the standard wiring. This wire must be connected to the green wire of the activator using female-male connectors. The blue wire must be short-circuited to vehicle ground. Now you can check how the electric trunk lock of the VAZ 2107 functions. It is enough to spend 2-3 hours so that the trunk will eventually open using the VAZ 2107 button. After completing the work, do not forget to connect the negative terminal to the battery.

Alternative trunk opening for VAZ 2107

Many owners of domestic cars, due to the lack of opportunity to purchase a more expensive vehicle, are trying to make their cars more comfortable. One of the options for improving the functionality of the VAZ 2107 is to control the trunk lock from the passenger compartment. This can be done either using a button or using a cable, which eliminates the need to open the mechanism with a key.

Opening with a button

As the owner of the “Seven”, equipping the car with a device for opening the trunk with a button will not be difficult. The positive aspects of the electric drive include the following:

convenience;
practicality;
following fashion.

Installing a trunk lock control button allows you to control the mechanism from inside the car.
Some motorists believe that such an option on the VAZ 2107 is useless, but it’s still worth trying and seeing the usefulness of such a device. If you have decided to install an electric trunk drive, then first you will need to prepare the necessary parts:

four-pin relay and a special terminal for it;
activator;
wires;
button;
female and male connectors, as well as electrical tape and heat shrink.

To install an electric lock on the trunk lid, you will need an electric drive, wires, connectors, terminals and a button.
The activator is an electric drive, the operation of which is based on retraction or repulsion, depending on the installation diagram. First you need to remove the lock and install the drive rod. In order to be able to influence the lock tongue, you need to drill a hole in the side of the mechanism and bend the rod itself slightly. Once the rod is secured, the lock can be put in place. To avoid adjusting the mechanism, you should first mark its location with a marker or pencil. Next, you need to secure the electric drive, which will require 2 screws and a plate included with the device. Having fixed the product on the lid, proceed to the connection stage.

To be able to control the trunk lock from a button, you will need to connect the electric drive rod to the tongue, and attach the activator itself to the trunk lid

Before starting electrical work, remove the negative terminal from the battery and study the connection diagram.

Installation of the electric lock is carried out according to the electrical diagram

The electric drive device is supplied with power directly from the battery or through a fuse. Electrical installation consists of the following steps:

Voltage is supplied from the battery to the relay in accordance with the diagram.
Relay contact No. 86 is connected to the electric lock control button. The button is located on the dashboard in a convenient place.
Using a wire, contact No. 30 of the relay is connected to the green conductor of the electric drive using connectors.
The blue wire of the electric lock is connected to the vehicle ground.
Check the operation of the device.

Exiting the trunk lock cable to the passenger compartment

The trunk lock on the “seven” can be opened using a cable pulled into the car’s interior. To implement this idea you will need:

cable 4 m long and 1.2 mm in diameter;
braid 4 m long from bicycle cables;
braid ends and cable clamps.

In order to be able to unlock the trunk lock using a cable, it is necessary to make holes in the mechanism to thread the cable and secure it to the tongue. Then they lay a cable from the lock to the driver's seat through the trunk lid, and install a suitable lever to open the mechanism. As a lever, you can use the hood opening mechanism from the VAZ 2109, on which the cable is attached. All that remains is to check the operation of the design.

Opening the trunk using the VAZ 2107 button

Opening the trunk of a car from a button in the cabin will no longer surprise anyone. Today, such an option on a car can significantly facilitate human labor. Domestic cars have only recently begun to be equipped with such useful options from the factory. But this does not mean at all that this option is not suitable for owners of VAZ-2107 injection and carburetor versions. If desired, you can make a semblance of a foreign car out of any domestic car and vice versa

In this material we will pay attention to the question of how to open the trunk from the button of a VAZ 2107. This procedure is not particularly difficult, especially if there is such a goal

Convenient button location

Automatic trunk opening on a VAZ 2107

Many owners of domestically produced cars from AvtoVAZ would like to exchange their cars for more comfortable and convenient foreign cars. The reason for this is mainly various automation systems, which significantly improve the ease of use of the car. If it is not possible to buy a better car, then you can at least improve the existing one. This is exactly what the author of this homemade product probably thought, and the first thing that came to his mind was the automated trunk opening on his VAZ 2107. Agree to press a button while sitting in the cabin, it is much more convenient than getting out of the car and opening the trunk with a key.

Luxury or necessity

The automatic trunk opening feature is found in many new cars. Drivers like this feature, because you quickly get used to good things. To open the luggage compartment in a car, just press a button in the cabin. The lock comes into operation as a result of the operation of the electric drive.

This feature may seem like a small thing and an insignificant addition until the cold weather arrives. In cold weather, the lock on the trunk often freezes, making opening the compartment a difficult task. You have to spend time defrosting the mechanism. In the case of an electric drive, such problems will not arise. Also, such a mechanism makes car hacking more difficult, which is also an important advantage.

Mostly imported cars are equipped with this function, and not all of them. Domestic manufacturers have only recently begun to equip their models with such functionality. Every car owner can equip his car with an electric drive for the trunk. This will not be difficult to do, but you will still have to tinker.

Everything you need to close and open the trunk

To get started, you should decide on a list of what you will need to assemble the electric drive. First of all, you must have an electric drive mechanism in stock, and you can buy it in almost every car store in any country. Of course, the electric drive mechanisms are the same in their functions, but they often differ from each other. There are car owners who try to make this kind of mechanism with their own hands. For reliability and confidence in its performance, it is necessary to install a factory mechanism. The complete set of the mechanism consists of:

1. Electrical wiring.

2. Terminals.

3. Motor.

4. Documents with instructions.

5. Buttons with safety lock.

Immediately ask for warranty service or repairs. Quite often such services are not provided in markets, but in car dealerships it is just the opposite. A typical set of materials and tools will be needed for installation. There are times when you need to have additional wires because the factory assembly is not enough. To secure the wires, purchase items for one-time use, such as:

· Insulating tape;

· Tubes;

· Clips.

All of the above serves as the main material for fastening and installing the electric trunk drive. The electric trunk drive is a mechanism consisting of the following connected devices:

1. Motor.

2. Fuse.

3. Button with rod.

In order for the rod to work, several types of drive are known. Often there are mechanisms with magnetic plates and an electric motor. The electric one is long-lasting and of high quality, which is why it is the most consumed. When you want to buy an electric drive, think carefully about the purposes for which it will be used. In case of opening, thanks to the button located inside the vehicle, then you can use the standard model, and if suddenly using a remote control with an alarm (remote), then you should get more funds. In the Russian Federation you can find several types of electric drives:

1. With reinforced fastening.

2. Side mounting.

3. Standard.

Don't forget, you have to take your gear purchase seriously. If you buy a fake of poor quality, you will not receive guaranteed reliability and long-term operation. Do not ignore goods that are produced in the Russian Federation, as many buyers do. In modern times, domestic electric drives are produced no worse than foreign ones.

Optimizing space in the seven

It is not at all necessary to have an apiary for twelve hives or a serious homestead, so that sometimes you need to transport a fairly large load or a lot of small items. Situations are different, and especially when going on a trip in a VAZ 2107, not everyone wants to burden themselves with a trailer. This is why there are additional luggage racks.

But first, let’s deal with the standard, ordinary trunk of the seven. It is far from the ideal of rational distribution of space, in fact, as in all classic Zhiguli cars. The side members, wheel arches, niches, gas tank and rear suspension cups form a kind of labyrinth for dumping all sorts of rubbish. Only the size of the trunk of a VAZ 2107 is quite difficult to measure with a tape measure. It turns out to be an intricate figure, however, there are heroes who did it. The photo shows the dimensions and geometry of the trunk.

Trunk lock device for VAZ 2107

The trunk lock of the VAZ 2107 consists of the following parts:

A retainer with a plate is installed on the car body, with which the rotor and lock body engage. If any of the parts is damaged, it must be replaced. If it simply does not work well, but there is no visible damage, you must first try to lubricate the device and adjust the position of the lock relative to the latch on the body. If these operations do not help, the part should be replaced with a new one.

What is needed for replacement

Before changing the trunk lock of a VAZ 2107, you need to stock up on four items:

10mm wrench (preferably a socket wrench);
installation (needed to adjust the closing force of the trunk lid);
pencil;
new trunk lock for VAZ 2107.

You will also need aerosol lubricant or “Litol”.

Do-it-yourself installation of an electric trunk drive on a VAZ classic VAZ 2107

First, we install the electric trunk drive itself. There's nothing complicated about it. We fasten the electric drive motor with self-tapping screws as shown in the photo.

Then we remove the lock and make a hole in it to insert the rod, as in the photo.

We pass the wiring through the holes in the trunk and through the cabin to the panel.

Then in the store I bought this special button.

Then I used an electric drill to drill a hole in the panel on the left, near the headlight hydraulic adjustment.

The luggage compartment is an integral part of every car, where you can transport various loads commensurate with the carrying capacity of the car. The trunk of the seventh model Zhiguli initially has no sound insulation, no attractive finish, no convenient lock control, which forces the owners of this car to think about modifications of various kinds.

Car rack and how to choose it

Trunk lock VAZ 2107

The luggage compartment lock of the VAZ 2107 has a simple design and fails extremely rarely, but sometimes it may be necessary to adjust or replace the mechanism.

Trunk lock malfunctions

Malfunctions of the trunk lock on Zhiguli cars of the seventh model are usually associated with malfunctions of the cylinder. In this case, the lock will need to be removed from the trunk lid and disassembled to replace the part. As for the adjustment, it is carried out when the luggage compartment lid does not close well or knocks while driving.

Trunk lock repair

To carry out repair work on the trunk lock, you will need to prepare the following list:

wrench 10;
installation;
pencil;
new lock or cylinder;
Litol lubricant.

How to remove

To remove the luggage compartment lock, perform the following procedure:

Mark the position of the lock on the lid with a pencil.
Using a 10mm wrench, unscrew the 2 nuts securing the lock.

Replacing the larva

If the need for dismantling is due to replacing the cylinder, then before installing a new part, the mechanism is cleaned and lubricated with Litol. If the lock is completely replaced, the new parts of the product are also lubricated.

How to put

After lubricating the lock, it is installed in the following sequence:

Insert the sealing element into the luggage compartment lid.
Place the lock cylinder in the spacer sleeve.
Mount the cylinder together with the bushing into the lock.
Install the lock on the trunk lid in accordance with the previously made marks.
Fasten and tighten the mechanism with two nuts.

Video: replacing the trunk lock on a VAZ 2107

How to adjust the trunk lock

If the trunk lid lock on the “seven” closes with difficulty, it needs to be adjusted relative to the locking element. To do this, loosen the fasteners and change the position of the mechanism so that the latch easily fits into the body and the lever secures it well, and there is an equal gap between the luggage compartment lid and the body over the entire area.

Adjusting the trunk lid

Sometimes it becomes necessary to adjust the trunk lid. It happens that the part is located above the rear wings or is shifted to the right or left. If the trunk lid can be moved to the sides by unscrewing the fastening nuts on the hinges, then with an incorrect height position the situation is somewhat different.

To adjust the lid in height, you will need to open it completely and, holding the edge of the lid with one hand, apply force in the hinge area with the other. A similar procedure should be repeated on the other side.

Installation and connection of an electric lock to the central locking

Car enthusiasts who have installed an electric lock on the trunk of their car with their own hands recommend using standard kits from retail chains. Installing high-quality components means ensuring the operational reliability of the electric lock.

Chinese manufacturers offer good installation kits for trunk lid locks. Machine kits include: electric drives; buttons; rod sets; wires with fuses; relyushki; installation strips. It is impossible to install electric locks without the appropriate tools and auxiliary materials, such as insulating, corrugated tubes, and fasteners.

Having decided to install it yourself, you will have to perform a number of plumbing works on the machine. This includes marking for electric lock components, drilling holes for fasteners, installation, fastening. The sequence of work is similar to the previous ones:

On the trunk of a particular car, locations for mounting an electric locking device are determined. After marking, installation holes are drilled, the drive and clamp are attached.
If necessary, the electric lock components are modified. The lock drive rods are installed with preliminary markings.
The battery terminals are disconnected; according to the electrical diagram, it is necessary to install and lay the wires and connect them to the appropriate contacts and connectors. Use a multimeter to check the correct connections of the electric lock on the trunk of the car. The terminals are connected to the battery.
The lock is connected to the main central locking button, or to an individual one installed in a convenient place inside the car.
The operation of the electric lock is checked. If necessary, adjustment and fitting work is carried out.

Power tailgate: what you need to know

So, an automatic trunk is undoubtedly a very convenient and practical solution. On high-end cars, you can open the trunk using the remote control (key) remotely.

There are also more advanced solutions, when it is enough to disarm the car and approach the car, then move your hand or foot in the area where the sensor is installed. In turn, the sensor “catch” the movement, sends a signal to the servo mechanism and the trunk opens without pressing any buttons on the remote control or in the cabin.

Of course, such solutions are complex and expensive. If we consider a simpler scheme, the trunk opening button is placed directly in the car interior, which eliminates the need to open it from the outside. In other words, the trunk with a button will allow you to separately open the trunk lock from the passenger compartment, which is simply irreplaceable in bad weather conditions and in a number of other cases.

It can be noted that this solution is quite possible to implement on almost any car (for example, an electric trunk of a VAZ). The convenience lies in the fact that when you press a button in the cabin, the electric drive activates the lock and the trunk lid opens. By the way, this trunk lock does not freeze.

The problem is familiar to owners of VAZ and other cars where it is not possible to open the trunk lid from the passenger compartment or remotely. Moreover, after washing or as a result of moisture, the lock simply freezes over, which prevents it from being opened with a key. In such a situation, you have to warm the lock, use anti-ice products, drive the car into a warm parking lot, stow luggage in the cabin, etc.

In turn, it is the electric drive that greatly facilitates and simplifies the operation of the car in winter. If the lock is working properly, the trunk lid with such a drive will open in any case.

Let us also pay attention to the fact that you can purchase both an electric trunk lock and an electric trunk drive. At the same time, you can buy and install an electric trunk drive without replacing the standard lock, that is, the device is compatible with a standard lock. This will allow you to open the trunk lid either in a standard way or using a button.

This will allow you to open the trunk lid either in a standard way or using a button.

Having considered the features and advantages, let’s move on to the electric drive device. Let us note right away that the electric drive and the trunk opening button are considered simple solutions. In short, the electric trunk drive is a mechanism that has an electric motor, a pair of 4-pin relays and a pusher rod. Also among the components is a fuse. A trunk button is installed in the cabin, which can be included in the kit or purchased separately.

Regarding the actuator, there are generally two types of actuators acting on the rod:

electric motor solution;
drive on magnetic plates;

As practice shows, the first option is simple, the most durable, durable, reliable and widespread, while the second is much less common. The reason is that the magnetic drive device is complex; malfunctions and failures often occur during operation. The general principle of operation is based on the interaction with magnetic plates. When power is applied, the relay “pulls” the rod to open the trunk.

As for the electric motor, the principle is similar to the operation of a central lock. The design is simple and reliable; if necessary, it can be integrated even into an old car (“classic” VAZ models, etc.). In fact, a signal from the button comes to the motor, it fires, pushes the rod and the lock opens.

I know that this topic has been covered more than once, but I still wanted to share how I implemented the idea. I recently bought my first car, a VAZ 21074i. I won’t say anything about the inconveniences I encountered, except for one. Owners of sevens (and probably fives) are familiar with the situation when you get into the car, start the engine, and then remember that you need to put something in or take it out of the trunk. You have to turn off the engine, take out the key, go and open the trunk with the key. Complete hemorrhage I often came across articles about how to open the trunk from the passenger compartment or from the alarm key fob. Craftsmen pulled all sorts of cables, etc., but I didn’t like this method, I wanted something simpler. And I found it on one site. Without thinking twice, I decided to do the same thing, but in a simpler way. I will only write about what I did in my own way, and what is not written in the article, the rest is here - https://moeauto.ru/tuning/el_004.html The author of the article had to turn to a turner and welder. I didn’t have such an opportunity, and it turned out that I didn’t need it. I went to the market and bought a locking mechanism there (for 60 rubles) and a Saturn electric drive (the most common one, for 70 rubles). I did not disassemble the lock, but I glued the extension cord to the piece of iron that the lock cylinder acts on with epoxy glue. As a piece of hardware, you can use a piece of metal fastening for the drive, which comes with it in the kit.

We drill a hole, sand both the piece of iron and the extension cord well, degrease it with acetone, generously coat it with epoxy, glue it and you can throw it behind the battery for a few days. There were no problems with this, the only thing is that you need to be careful with the length of the extension so that it does not touch the trunk lid. To do this, it is better to measure the distance on the “native” mechanism. For traction I used a steel knitting needle borrowed from my mother. After installing the drive and dismantling the old mechanism onto our modernized one, we naturally want to check how it all works. By that time, I was unable to run the wire from the passenger compartment to the trunk, so I used a regular wire connected to the drive and to the cigarette lighter socket. The drive power was enough to open the lock, but a small BUT arose. For the trunk to close, it is necessary that the piece of iron pushed by the cylinder returns to its original position. This did not happen due to the inertia of my drive. There were two ways to solve the problem. Either put a spring on this very piece of hardware, or on the drive. The first one disappeared because there was nowhere to secure it and there was no need. It is better to put a spring on the drive itself. It didn’t take long to find a spring; I had to deprive my nephew’s radio-controlled car of one shock absorber. I removed the rubber band from the drive and screwed the spring into it. Its force was enough for the drive to return to its original position after compression. Reinstalled the drive and the lid is ready to be easily opened by the drive and closed without any problems. Along the way, I’ll tell you how to run a wire from the trunk to the passenger compartment, because... I didn’t know myself and had to spend a couple of hours on it. The wire comes out into the cabin from the trunk under the rear seat, more precisely under the side backrest. You need to pull out the bottom seat (it is attached to the floor with rubber “fangs”, so you just need to strongly pull up the edge of the seat on both sides), bend the metal latches of the side one and remove it. When the seats are removed, on the right side you can see a bunch of wires coming from the trunk and glued with black tape directly to the body. She dives under the plywood that serves as a partition for the trunk and interior. You need to bend it a little where the wires go into the trunk and run our wire through.

I had to tinker a lot with the connection. My alarm system has an additional control channel. But the channel current is massive, -300 mA. Accordingly, the channel itself cannot be connected to the drive, the current will not be enough. You need to purchase a relay (the most common, 5-pin, car relay, I took a Saturn, bought it for 75 rubles. Together with the block). I supplied the relay with “+” from the clock, an additional channel, and a wire (“+”) from the drive. The drive ground was also shorted to the clock. “+” from the clock was fed through a fuse (15 A), attached directly to the wire, and made a jumper on the relay. I read the diagram for connecting the wires to the relay on some forum: we put an additional connection on pin 86. alarm channel, 85 “+” from the clock, 87 “+” to the drive, jumper to 85 and 30. And of course I made a button. I installed it instead of a plug in the button block (dimensions, heated rear window, fog lights and plug). Although this is not a button, but a switch similar to the fog lamp switch. It acts as a button only in its extreme position.

You just need to call his contacts (there are 7 of them). The “button” closes the “+” (stretched from the marker next door) and feeds it to the drive (so I connected 2 wires “+” to the drive and “+” from the button to output 87 of the relay). Lapota. I don’t at all regret the time I spent on this work (and not much of it was spent.). Now it’s winter and immediately one + appears on the face - now according to “B”, whether the lock cylinder is frozen or not, the trunk still opens easily. And before, you had to fiddle around with a key for a long time, for example, first to get a shovel, and then to pull the car out of the snow. In addition, I tightened up some crap there (sorry, I don’t know what they are called) and the trunk lid now immediately opens wide.

Benefits of this option

Convenience. By the time the driver leaves the cabin, the trunk will already be open.
Practicality. There is no need to remove the keys from the ignition switch to open the trunk with the key, especially if you have just started the engine and are warming it up.
Fashion. Almost all modern cars are equipped with such an interesting option, so the “seven” with this function will look more interesting against their background, especially with tuning.

Next, we’ll look at what the procedure for installing an electric drive for opening the trunk on a VAZ 2107 is with your own hands.

What is required for the work

Before starting the work process, you should purchase the necessary equipment. To carry out the work you will need:

A button that, when pressed, will activate the electric drive. The best option is a button from a VAZ-2110 car, the cost of which is about 50-80 rubles.
The relay is four-pin and has a special terminal for it.
Activator.
Wires.
Female and male connectors, as well as electrical tape and heat shrink.

You can easily find any of the components in any auto store, and then install and connect it to your car yourself.

Installation of the activator

Connecting the product

Before carrying out connection work, be sure to disconnect the negative terminal from the battery. To begin with, we present the diagram according to which the product will function.

Electric trunk opening for VAZ 2107

I really don’t like the way the trunk lock works in the VAZ-2107. To open the trunk you always need a key. I was tired of this business right away, and I also wanted the convenience of being able to open the trunk with a button from the passenger compartment and from the alarm key fob, especially since the alarm system has a so-called “additional channel”, which is used to connect the electric drive for opening the trunk.

When I was doing the soundproofing of the interior, I already thought that sooner or later I would make an electric trunk opening, so I laid several of my wires in the trunk. One of these wires was just a constant positive from the battery, and the second went from the alarm unit to the trunk but was not connected to anything. I'll get back to the wiring later, but now let's talk about the drive itself. class=content> The standard trunk lock was used as the basis for the electric drive; I bought it for as much as 25 rubles. After that I started to figure out how it works. To do this it was necessary to open it. The lock is disposable, it has rivets that I quickly drilled out with a regular drill. class=content> The lock consists of two halves, one is iron and the other is plastic. Inside there were two pieces of iron and one spring. Everything is just outrageous. One piece of iron interacts with the counterpart of the lock, and the second fixes the first in the closed position and opens when the lock cylinder acts on it. class=content> Having figured out the design, I first ordered a turner to replace the old rivets with new bolts of a similar shape, only in the place where it was riveted before, I ordered an M4 thread. The fact is that these rivets are not only fasteners for two halves, but also axles for two pieces of iron, so new bolts must be made as identical as possible to the old rivets. My turner did it accurately only the second time (in the top photo, these bolts are on the right along with nuts and washers). class=content> Now it's time to brainstorm. I definitely wanted to make sure that the lock could be opened with both an electric drive and a key. In addition, I did not want to buy a specialized actuator (solenoid) for luggage racks, but wanted to make do with a regular door actuator. In the classics conference at www.auto.ru there were people who made their own electric trunk drive, but most of them did it with the help of a cable that went inside the lock. I didn't like this decision. As always, I went my own way. I decided to lengthen the piece of iron that the larva acts on and connect the rod from the electric drive to this extension. The extension cord was made of flat 2 mm steel. This extension cord was simply welded to the original piece of hardware, but not on the side where the lock cylinder acts, but on the opposite side. Thus, the possibility of unlocking the lock with a key remained completely. You shouldn’t make this extension cord too long, otherwise the lock simply won’t fit into place. I was lucky, I made the extension so long that it turned out to be as long as possible, and I didn’t measure anything in advance (if you make it longer, then when you put the lock in place, this extension will rest against the metal of the trunk lid).

In order for the lock to close (to connect the two halves), it was necessary to saw off the upper part of the plastic part, this is where the extension will move. Then I lubricated all parts of the lock (for some reason, the new lock bought at the store had no lubricant at all), put all the pieces of iron in their places and connected the halves of the lock. There is a very important point here - when you tighten the halves with nuts, the main thing is not to overdo it. Because if you tighten it too much, the pieces of iron lose freedom of movement and begin to “wedge”, and if you tighten too loosely, then the piece of hardware that the lock cylinder acts on begins to dangle and, accordingly, the lock itself begins to dangle (perhaps this was only the case for me). In any case, you need to check that the pieces of iron are not loose or pinched. Then we try on the lock in its regular place. If the extension cord is too long, shorten it locally. After we have decided on the length of the extension cord, we drill a hole in it (in the extension cord) with a diameter of 4.5 - 5 mm. The hole should be drilled as close as possible to the end of the extension (there will be a larger lever). After this, we secure the lock completely, check that it opens normally with the key (it is better to do this without slamming the trunk, but simply simulating closing it manually), and adjust it so that the trunk lid takes its normal position when closing. Now we take a regular door drive. It is better to buy a drive from well-known companies (this is a topic for a separate discussion); it is even better to buy a “reinforced” drive, this is when its opening force is not 3-4 kg, but 7-8 kg. Normal installers install such drives in rear doors, especially Volgas. Included with the drive itself is a bracket in the form of a strip with many holes (we don’t need it), an adapter in the form of a cube with three bolts (we don’t need that either) and a rod with a flare on one side (that’s what we need). We take the drive and try it on the trunk lid, there are large oval holes on the lid, so we need to secure it so that the fastening bolts do not fall into these holes. I secured the drives with two self-tapping screws that are used to secure drywall (I immediately fell in love with these screws). Instead of washers I used two nuts. Now one of the most important and precise operations is bending the rod (rod) in place. You need to manually move the drive back and forth, move the extension cord and decide what length and shape the rod should be. I got it right the first time. What this thrust looks like can also be clearly seen in the photo. On the drive side, the rod is attached with a standard flaring, but on the extension side, I simply bent the rod 90 degrees with pliers. This is quite enough. In addition, with this fastening, you can remove the rod without removing the lock. When installing, you must first insert the rod into the electric drive, then insert it into the extension, and only then screw the electric drive to the trunk lid. In addition, the extension cord can move freely along the rod, so the rod does not interfere with opening the lock with a key. In general, I thought of EVERYTHING!!! Now the most crucial moment has come and the time has come to answer the main question - whether the force of the electric door drive is enough to open the trunk lock. I had a standard SATURN electric drive. Once the installation was complete, I routed the two wires from the drive to the outside of the trunk and closed the trunk lid. (Everyone is tensely waiting to see what will happen...) I sent an opening impulse to the electric drive and... (what do you think happened?). And-and-and-and-and... I won’t bog you down, everything WORKS!!! The power of the electric drive was quite enough to open the trunk, and the force of the spring in the lock was enough to return the electric drive to its original position!!! In short, everything worked, and perfectly! In addition, I noticed such a moment that if you open the trunk and simply “click” the drive, then after retracting it ITSELF returns to the extended position, the impulse is short, it simply pushes the drive into compression and, by inertia, the drive goes into decompression. In short, a FAIRY TALE!!! After checking the functionality, I started connecting the wiring (I tried just pieces of wire). After a long search for documentation for my alarm, I read in it that the control signal for the second channel is half-amp “ground”. This means control through the ground, making a button in the cabin is much simpler, you don’t have to look for a plus, just short it to ground and that’s it. As I wrote above, the wire from the alarm system to the trunk had already been stretched a long time ago, and there was also a plus in the trunk. All that was left was to solder the plugs onto these wires and hang the relay; you didn’t even have to make a mass, since the control signal became the mass. To be sure, I wrapped the reel with electrical tape and stuck it away. The drive has two wires, since the drive is used only for retracting one of the wires, I grounded it on the trunk lid next to the drive, and extended the second wire and ran it to the relay inside the trunk lid reinforcement box. Yes, in addition to opening from the alarm key fob, you can open it with a button from the interior; you need a simple button that will short the wire to ground to the drive. I have the wire, but I haven’t found a nice button yet, as soon as I find it, I’ll install it right away. From the moment the electric drive was installed to the time of writing this article, a lot of time passed, during this time no problems arose, but gas station attendants were often surprised (at gas stations the gun is attached by gas station workers) when the trunk opened “by itself” In addition, I finally bought a decent button for opening the trunk from the passenger compartment. By chance, in the store, I saw a button from a Niva specifically for opening the trunk, it even had the corresponding symbol on it. And I immediately bought this button for only 20 rubles. I placed the button itself in place of the standard control knob for the headlight hydrocorrector. The fact is that I didn’t have this hydraulic corrector at all and there was a hole in the panel for its handle. I cut out a plate of the appropriate size from black plastic and attached the button.

Electric trunk opening VAZ 2105

How to open a VAZ2107 without a key

Hello. On my channel you need to have a great conversation while watching good videos

on various topics.

Next, at one end of the found wire we make a hook at an angle of 45 and about 2 cm long. After completing the preliminary work, we proceed to opening the lock. We plant the formed hook into the gap between the door and the glass.

If the wire rests against an obstacle (usually a locking device mechanism), we bypass the lock and search for a special mechanism to open the door. This is done in this way: without weakening the pressure on the wire when it rests against an obstacle, we move the hook to the right side right until the moment it falls through. After a while, we turn it to the right.

We find the mechanism for locking the lock, which without experience is done through countless attempts. If this mechanism has been found, then hook it with a hook and pull the wire. The lock should open. For those who are still wondering how to open a car without a key at home, we offer the 2nd method: You can open a car lock without a key by using a narrow rope along another fishing line (these things are definitely found among those guys who do). For this purpose, it is necessary to perform the following steps: At the base of the selected rope, or fishing line, we tie a loop, which must be the size of the internal door lock button.
