How to remove the ignition switch on a VAZ 2107? this will definitely come in handy renoshka.ru

What is this node?

This device is almost identical in design, with the exception of a few small elements, for all early releases of VAZ models. The castle consists of two parts independent from each other. This is the lock itself, which turns on and off all car systems, and the contact group, which performs these switches. The independence of these parts of the device allows, if one of them fails, to replace only the failed one.

To remove and replace this unit, you do not need to purchase any special tools or accessories. It is enough to have at your disposal a set of flat and Phillips screwdrivers, and you will also need pliers. You also need your hands to grow from “that place” and a clear head to figure out what, where and how to unscrew or pull out.

What is a distributor

This is a device that allows you to correctly distribute high voltage across the spark plug electrodes. The design of the entire system consists of the following elements:

Power source: battery and generator.
Low voltage wiring.
Ignition coil.
Armored wires (designed to transmit high voltage).
Distributor (distributor) with contact group or Hall sensor. The VAZ-2106 distributor cover is necessary for high voltage switching.
Switch (in the case of a contactless system).
Capacitor - necessary to get rid of the variable component in the circuit.

The VAZ-2106 distributor has a relatively simple design, but it requires timely maintenance and replacement of worn-out elements.

Why is this necessary?

There are not many reasons why this unit has to be dismantled, but they exist. It is not at all necessary that this be due to its failure or problems with the contact group. But basically such an operation is carried out under the following circumstances:

Failure of the mechanical part of the lock;
The key is not inserted into the lock (or is inserted but does not turn);

Problems with the anti-theft device on the steering column;
When turning the key in the ignition switch, the vehicle's power supply does not connect.

As can be seen from the listed points, problems can arise in both parts of this unit, and to eliminate them it must be removed from the steering column mounting bracket. If problems arise in the contact group, it is replaced with a new product. The same can be said about the lock itself; if the larvae fall out, it is easier to replace the entire assembly than to try to insert them into place.

Problems with the ignition module

The ignition module is an electronic analogue of a distributor (see VAZ distributor design: the difference between contact and non-contact ignition systems and ignition timing adjustment) and an ignition coil. A faulty module can fail at the wrong moment, according to the famous law of meanness. Checking it and identifying malfunctions will take no more than an hour, but it will allow you to determine the approach of serious problems in time.

So:

The main symptom of a module malfunction is the absence of a spark in one or several cylinders at once.
In this case, the engine stalls or does not start at all.
The second common phenomenon is a failure in the timing of the ignition cycle, due to which it is impossible to coordinate the interaction of the piston and gas distribution system with the module
There are several methods for identifying module malfunctions

How is it dismantled?

The necessary tool has already been said, there is nothing more to add, we hope that it is near you and ready for use. If that's the case, then let's start. Before starting work, you need to turn off the power to the car. To do this, simply turn off the vehicle's main switch or remove the negative terminal from the battery. After this, you can sit more comfortably in the driver’s seat and begin removing the ignition switch.

This can be done in the following sequence:

First of all, it is necessary to remove the decorative cover that covers the steering column mounting bracket, the steering column switch and the ignition switch. To do this, just use a Phillips screwdriver to unscrew five screws, one of which secures the lower part of this casing to the steering column, and the other four fasten the halves of the casing together;

Carefully remove the upper part of the decorative casing, then the lower part. At the same time, do not lose the sealing rubber of the lock head;

Next, before proceeding directly to dismantling the lock, you should pay attention to how the wires are connected to the contact group. There may be two connection options. The wires can be inserted into a plastic non-separable connector, which is easy to remove and put back in place. Or maybe they were connected separately. In the latter case, you need to take a pen and paper and write down the order of their installation on the contact group;

After disconnecting the connector with wires, you can begin to remove the lock itself. To do this, use a Phillips screwdriver to remove two small screws from the sides that secure its body in the bracket;

After this, you need to insert the key into the lock and turn it to position “0”, this is necessary to disable the steering shaft lock;

Now, using a thin screwdriver or an awl, you need to push the latch inside, which is located on the left side of its body;

Now you can try to remove it from its place. This is done by pulling the inserted key while holding the recessed latch.

That's all, now you can begin the procedures that led to the dismantling. We told all interested parties in an accessible language how to remove the ignition switch on a VAZ 2107. I would like to hope that you do not have any questions about this, and the dismantling operation will be successful.

How to change

After diagnosis, we proceed to removal and replacement.

Required Tools

If a breakdown is detected in the lock, you will need to prepare the following tools for disassembly:

flat screwdriver;
crosshead screwdriver;
awl.

How to make a withdrawal (step by step with photo)

All elements of the mechanism are connected to each other using ordinary bolts, which can be removed without the use of brute physical force. The procedure for removing the old lock is as follows:

We disconnect the battery so as not to accidentally short the wires during operation.
Insert the key into the lock and turn it 90 degrees. In this position, the steering shaft will be blocked and will not interfere with dismantling.

Before disassembling the device, turn the key in the ignition switch 90 degrees
To remove the plastic casing, unscrew the 5 bolts that connect the upper and lower parts.
Carefully remove both parts of the casing.

After unscrewing the bolts, both parts of the casing can be easily removed from the bracket
Unscrew the two screws that hold the lock. They are located on either side of the switch.

To remove the ignition switch, you need to unscrew the two mounting bolts
Disconnect the wires from the ignition contact group.
Insert an awl into the flat hole on the bracket and press the latch to move the latch.

Remove the fastening bolt and use an awl to press the lock through the flat hole.
We pry the mechanism with a flat screwdriver and remove it from the bracket.

After removing the bolts and pressing the lock, the ignition switch can be easily pulled out

Checking and repairing the contact group, installing and connecting a new lock

If you decide to replace only the contact group, you will need to remove the ring with a flat screwdriver - and the part will come off. When installing new contacts, it is necessary to place the groove on the secret part so that a slight engagement occurs. After that, we clamp everything with a spring ring.

Installing a new lock proceeds as follows:

Insert the key and turn it to the “0” mark.
We clamp the latch and at the same time insert the switch into the bracket.
We connect the wires according to the diagram.

We connect the wires by color, as indicated in the diagram
We install the two parts of the casing and fasten them with bolts.

Tip: When connecting pins, it is important to use the correct diagram. If you connect different poles, the wiring may short out, which will lead to damage to electrical appliances.

How to remove the ignition switch on a VAZ 2107? This will definitely come in handy

In this regard, there are some features of its dismantling. The design of the ignition switch is simple and reliable, causing few problems for car owners.

How to remove the ignition switch on a VAZ 2107

will become clear after reading this article. Without this device it is difficult, although possible, to start the engine. But one more problem remains: the steering wheel remains locked until the key is turned in the lock, and this, many will agree with me, is already a problem not only for the thief, but also for the owner of the car.

Failure of the mechanical part of the lock;

The key is not inserted into the lock (or inserted);

Problems with the anti-theft device on the steering column;

When turning the key in the ignition switch, the vehicle's power supply does not connect.

Steering lock testing

Testing the steering wheel
If you do not check the operation of the steering wheel lock, you may encounter certain problems in the future. Therefore, do not waste your time on this event. It consists of removing the key from the ignition and turning the steering wheel at a slight angle.

If there is no lock, you will need to slightly adjust the position of the lock. Make sure it fits into the groove located on the steering shaft.
If the locking is effective, you will only need to tighten the four installed breakaway bolts until they stop. Twist until the heads break.

When the lock installation is completed and the test has passed, do not forget to connect the device to power and start the engine. If it starts, all systems dependent on the ignition switch are working, you can fully begin reassembly. Follow the reverse instructions for removing the casing and steering column switches. It would not be amiss to check the condition of certain nodes along the way. It is quite possible that some of them also need replacement or a little preventive maintenance.

Ignition switch VAZ 2107

The ignition switch (IZ) of the VAZ 2107 is an electromechanical type device. It is located under the dashboard and is attached to a bracket welded to the left side of the steering column shaft.

Purpose of the ignition switch

The main function of the protection system is to synchronize electrical systems when starting and operating the vehicle. When you turn the key in the lock, current begins to flow to the starter solenoid relay, to the ignition system, to instrumentation and lighting devices, heater, etc. When the ignition switch is turned off, most of the electrical equipment is completely de-energized, protecting the battery from discharge. At the same time, the anti-theft mechanism is activated, blocking the steering wheel at the slightest turn.

The key in the ZZ VAZ 2107 can occupy four positions, three of which are fixed:

0 — “Disabled.” Electrical wiring is de-energized. The key cannot be removed from the lock; the anti-theft mechanism is disabled.
I - “Ignition”. The engine spark system, generator excitation, instrumentation, exterior lighting, windshield wiper blades, heater and turn signals are included. The key cannot be removed from the lock; the anti-theft mechanism is disabled.
II - “Starter”. Current is supplied to the starter. The position of the key is not fixed, so it must be forcibly held in this position. It cannot be removed from the lock.
III - "Parking". Everything is turned off except the sound signal, side lights, windshield wiper blades and interior heating stove. When the key is removed from the lock, the anti-theft mechanism is activated. When turning the steering wheel in any direction, it will be locked. To confirm the locking, a sound signal will be heard - a click. To disable the anti-theft system, you need to insert the key into the lock, set it to position “0” and smoothly turn the steering wheel in any direction until it unlocks.

Diagnosis of ignition switch faults

The ignition switch of the VAZ 2107 is quite reliable in operation and usually fails only due to the exhaustion of its service life. ZZ malfunctions can be mechanical and electrical.

The key in the lock is stuck or won't turn

Sometimes the key in the 3Z turns with difficulty or does not turn at all. This is usually associated with a lack of lubrication in the lock cylinder - the movable disk with the plates begins to jam. Also, the cause of this situation may be damage to the working part of the key. The problem can be temporarily solved by pouring water-repellent WD-40 into the lock and replacing the faulty key with a new one. However, after some time the lock will still have to be changed.

A breakdown of the mechanical part of the ignition switch forces many Zhiguli owners to change it entirely, since the cost of the complete lock is not much different from the price of its secret part.

Devices do not turn on

If electrical appliances do not start working when you turn the key, this may be due to burnt contacts due to loose contact with each other. The situation can be corrected by cleaning all contacts with sandpaper, and the connection point of the pink wire going to contact 30 from the positive terminal of the battery should be tightened with pliers.

The starter does not turn

If the starter does not spin when the ignition is turned on, the reason for this is most often a burnt out or loose fit of the contact pair responsible for the operation of the starting device. This can be checked using a multimeter, and corrected by replacing the mechanism responsible for distributing current in the lock. The contact group can be changed without dismantling the CB. Before doing this, it is recommended to check the functionality of the starter relay with a multimeter.

Lights and windshield wiper do not work

When the lights and wipers do not turn on when you turn the key, you need to check the condition of the INT output contacts. If the lock is working properly, the problem should be looked for in other components - switches, switches, fuse box, etc.

Repair of ignition switch VAZ 2107

Removing the ignition switch of a VAZ 2107 is quite simple. To do this you only need:

Procedure for removing the ignition switch

To remove the ignition switch, you need to perform a number of steps in the following order:

Disconnect the negative terminal from the battery.
Unscrew the screws securing the lower steering column casing and remove it.

Disassembling the ignition switch

In case of failure of the contact group, which is not repaired but replaced entirely, it can be easily removed from the lock body. The procedure is as follows:

Use a screwdriver or an awl to pry up the locking ring and remove the contact mechanism.

Assembling and installing the ignition switch is carried out in the reverse order.

Choosing a new lock

The ignition switch device is the same for all classic VAZ models. However, cars manufactured before 1986 were equipped with locks with seven contacts, and after 1986 - with six. For the VAZ 2107, any lock for classic Zhiguli cars with six contact pins is suitable.

Removing the device from the car

In order to know how to remove the ignition switch on a VAZ-2107 car, you need to have an understanding of not only its functionality, but also its structure.
This element in Zhiguli consists of two parts - a switching mechanism and a contact board. The importance of both components is also significant because if one fails, the entire device will not work. You may need to remove the lock for various reasons:

the device does not work, although the key is not broken;
jammed key when the steering wheel is locked;
the broken key remained a secret;
the owner lost his car keys, etc.

Step-by-step dismantling of the lock:

Remove the decorative cover of the steering shaft.
De-energize the vehicle by disconnecting the negative terminal of the battery.
Disconnect the wire bundle from the lock.
Insert the key and turn it to the zero position - “Off”. During this, you need to turn the steering wheel slightly left and right to move the locked steering shaft to the required position and disable the anti-theft mechanism.
Loosen the lock fastening by removing the screws securing the steering shaft bracket.
Use an awl, a small screwdriver or strong wire to press out the fastener.
Pull the lock out of its seat.

After this, you can replace the non-working device with a purchased new one, repair the group of contacts, the cylinder.
But first, it would be better to check the supposedly broken element for functionality, maybe it’s not the problem. To check the ignition switch you will need an ohmmeter, also called a multimeter.

In turn, connect the terminals of the device to the lock terminals that correspond to the specific position of the key in it. Resistance tending to zero indicates that the contact group is in good working order. If the resistance is greater than zero, the contacts are burnt or oxidized.

In order to replace a group of lock contacts, it is enough to: remove the locking ring from its base, remove the group itself from the device body and replace it with a new one.

If you don’t want to do this yourself, you can always turn to specialists for help.

Installing the "Start" button

Some car enthusiasts install a separate button in the car in a convenient place to start the engine. It is connected to the starter circuit by breaking the red wire going to terminal 50 on the ignition switch. The car is started as follows:

The key is inserted into the ignition switch.
The key is turned to position "I".
Pressing the button turns on the starter.
After the engine starts, the button is released.

In this case, you can turn off the engine only by turning the key in the opposite direction.

In order to use a button to stop the motor, that is, to turn it into a “Start-Stop” button, you need to use two additional relays:

headlight relay RS 711;
starter relay 113.3747–10 or 90.3747–10.

When you press the button, current from the battery goes to the headlight relay, closing its contacts, and then to the starter. When the engine starts, the button is released, opening the contacts of the starter relay and breaking its circuit. However, the positive wire remains connected through the headlight relay for some time. When you press the button again, the headlight relay contacts open, breaking the ignition circuit, and the engine stops. To delay the activation of the starter, an additional transistor is included in the circuit.

Thus, even a novice car enthusiast can replace the ignition switch of a VAZ 2107. To do this, you need a minimum set of tools and following the recommendations of specialists. Particular attention should be paid to the correct connection of the wires to the lock contacts.

Removal and installation

Removing this element from the car is quite simple and all you need is a Phillips screwdriver and a thin flat-head screwdriver or an awl. Before starting work, be sure to disconnect the negative terminal from the battery.

To get to the fastening of this element, you will first need to unscrew the bolts securing the lower facing panel of the steering column, and then remove it.

Afterwards, you need to unscrew the two bolts securing the lock, which hold it in its seat. In the same seat there is a small technological hole. By inserting a thin screwdriver into this hole, you need to press the latch that holds the lock, and then push it out of its seat.

Only then disconnect all the wires. On some models, the wiring going to the lock is collected in a chip that is put on the contacts of the lock. This feature will greatly facilitate the installation of a new element, since such a VAZ-2101 ignition switch does not require a wiring diagram.

Remove the two screws securing the ignition switch (bottom view).	Insert the key into the ignition switch, turn it to position “0” (turning off the anti-theft device), press the lock with a screwdriver through the hole in the bracket and...
...remove the switch from the bracket and the key from the switch.	Label (or remember the connection order) the wires and terminals of the ignition switch. Disconnect the wires from the switch.

But there are also versions of the car in which the wiring is directly connected to the contacts, and when installing a new element with this type of wiring connection on a VAZ-2101, an ignition switch circuit will be required.

If the lock assembly is replaced, then you can connect the wiring to the new one, install it in place, secure it and cover it with a decorative panel.

If only the contact group is changed, then the removed lock is disassembled. The contact group is fixed using a locking ring, which must be pryed off with an awl or screwdriver and removed. After this you can remove the group. A new one is installed in its place and secured with the same retaining ring. After this, everything is put in place and the VAZ-2101 ignition switch is connected.

Removing the ignition switch on a VAZ 2107 step-by-step description to help the car owner

The key element of the car is the ignition switch, which is entrusted with the task of controlling the electrical system. The main purpose of the ignition switch on a VAZ 2107 is to start the engine. In addition, if this element on the car is faulty, then the wipers, heater, heated rear window, as well as low and high beams will not work. If it fails, you will need to replace the ignition switch of the VAZ 2107, which is quite possible to do yourself, following the instructions.

Ignition switch device for VAZ 2107

An ignition switch is a cylindrical part that consists of making and breaking contacts inside. On the end side, the ignition switch has a recess for inserting a key. The second end of the cylindrical body has a block with contacts for connecting a plug with electrical wiring. All keys have a universal design, so they are suitable exclusively for “their” locks.

The side of the body has a protrusion, the main purpose of which is to lock the steering wheel in one position. This lock is automatically activated immediately after the key is removed from the ignition switch. Inside, the part consists of two parts - this is the cylinder, which includes the ignition key, as well as a contact group. Scrolling the cylinder causes the contacts to close and open.

On injection and carburetor models of the VAZ 2107, ignition switches of the same design are used.

The cylinder is the internal part into which the key is inserted and which interacts with it. This element in the lock design has a movable locking pin, which moves when the key is rotated in a clockwise direction. When the key is turned in the opposite direction in the lock (the ignition is turned off), the finger moves out.

When the car owner leaves the vehicle, removing the key from the lock, the finger enters a special recess in the steering column, blocking the steering wheel from rotating in one position. This is an anti-theft system that prevents the car from being stolen without a key. If the larva fails, it can be replaced separately, without a contact group, but using a new key. To replace, you will need to dismantle the lock and remove the cylinder.

Contact connector

The contact group of the VAZ 2107 ignition switch (lower part) consists of two elements. The first element is a movable disk on which conductive plates are located. The second part is a block with contacts in the form of protrusions that connect to the conductive plates.

The movable plate is driven by the lock cylinder when the key is turned. The fixed plate on the outside has protrusions - terminals, through which the supply wires are connected. To connect the wires to the 3Z, a plastic block or chip is used. This connection to the lock is called quick-release.

Connection diagram

The connection diagram for the VAZ 2107 ignition switch is implemented using a plastic chip, which is connected to the contacts of a fixed plate on the back of the mechanism. The chip contains wires of different colors, which are responsible for the operation of electrical appliances on the car. Let's look at what the wiring diagram for connecting the wires to the ignition switch of a VAZ 2107 is. This chip has digital symbols. Wires of different colors are connected to each plug, the purpose of which we will learn further.

The red wire numbered “50” is responsible for supplying power to the starter relay.
Contact “15”, to which a double blue wire with a black stripe is connected, is responsible for supplying power to the heater, ignition and front panel instruments.
Contact “30” with the pink wire on the chip is the positive contact coming from the battery.
The “30/1” terminal with the brown wire is the positive power supply through which electrical appliances operate.
Contact “1NT” - has a black double wire on the chip, and is responsible for the operation of the brake lights.

Below is a pinout diagram for the ignition switch of a VAZ 2107 carburetor type. VAZ-2107 injection models have a similar circuit, only a pink double wire with a black stripe is connected to the 1NT contact. This wire is also additionally responsible for supplying power to the fuel pump.

When is a lock replacement necessary?

Repair of the ignition switch on a VAZ 2107 must be carried out immediately after its malfunction occurs. To repair a part, it will need to be removed from the car. There is an action algorithm for this. Before you remove the lock from the seven and repair it, replace the whole or individual mechanisms, you need to understand the types of breakdowns that occur.

The key does not turn in the lock or is stuck - this may be due to a defect in the key or lack of lubrication inside the switch. If the key does not turn, then you need to check its condition. It is recommended to use a spare key, which will allow you to verify the cause of the malfunction. If the jamming does not work with the second key, then the reason is in the cylinder mechanism. It is necessary to lubricate the inside of the cylinder using silicone grease. If this does not help, then the lock should be dismantled and replaced completely or just the cylinder.
When you turn the key, electrical appliances do not turn on - if the lights on the dash do not light up when you turn the key, then the first thing you need to do is make sure that the battery is working properly. If the battery is working and power is supplied to the chip, then the reason must be looked for in the design of the lock. Typically, device failure is associated with burnt contacts. It’s easy to correct the situation, but to do this you will need to remove the seal and disassemble it. Carbon deposits on the contacts (contact group) can be removed with fine-grained sandpaper. You also need to make sure that the wire tips are tightly connected to the contacts on the plate.
The starter does not spin - if, when you try to start the engine, there is no sound from the starter, then you first need to check the contact in the 3Z, which is responsible for supplying power to the starting mechanism. If the contact is burnt, it should be cleaned, and if damaged, the contact group should be replaced.
Lights do not work - such a malfunction may also be associated with a malfunction in the lock. To make sure that the reason is in the fault, it is necessary to disassemble it and check it.

The ignition switch must be replaced if the cylinder and contact group are faulty. Usually, if a larva fails, it is replaced separately without a contact group. The contact group is replaced in the same way in case of wear or abrasion of the contacts.

Removing the ignition switch

If there is a need to repair or replace the VAZ 2107 ignition switch, then it must first be removed. How to remove the ignition switch on a VAZ 2107 is a common question, since there are difficulties in dismantling this element. To do this, you will need to follow the following instructions:

Disconnect the terminal from the negative terminal of the battery.
Place the key in the ignition and turn it to the “Off” position. The key remains in the device, otherwise it will not be possible to dismantle it.
Unscrew 5 mounting screws, which are located inside the plastic casing covering the switch. After this, the plastic cover should be removed.
Unscrew the screws securing the device to the bracket.
Using a thin slotted screwdriver, press the latch.
Pull the part towards you, pushing it from behind by the plastic chip.
Pull out the lock, first disconnecting the contact chip with the wires.

Next, the components of the switch are repaired or replaced. Installation of the device is carried out in the reverse order of removal. There should be no difficulties with dismantling, and replacement usually takes no more than 30 minutes.

When installing a new mechanism, it is necessary to lubricate the cylinder and the rotating elements of the contact chip. Operating a vehicle with a faulty lock is just as dangerous as driving with a broken generator.

How to check the ignition switch elements for functionality?

To check functionality you need to perform the following steps:

Check the operation of the locking element. To do this, you need to carry out a working cycle of the lock and make sure that the bolt extends when the key is installed at point “III”. When passing the “0” mark, the latch tongue should go inward. The rotation of the larva should occur without jamming.
Try to remove the key in all positions. A working cylinder allows the key to be removed only at point “III”.
Make a small stand that allows you to connect a constant 12 volt power supply to the lock. In fact, you need to connect the lock directly to a battery or other power source.
Place the key in position “0” and check the presence of power at terminals 30 and 30/1. Testing is performed with a multimeter or test light.
Turn the key to point “I”. Check the presence of voltage in sections of circuits 30/1NT, as well as 30/1-15.
In the next position “II” the 30/50 chain is additionally ringed. The key must be held in this position as it returns under the force of the spring.
At point “III” the power supply to circuits 30/1NT and 30/1 is controlled.

When is it necessary to replace the ignition switch in a car?

You have to change the lock on a VAZ 2107 in the following cases:

Sticking of the key bit when installing into the cylinder or when turning. A number of owners delay the replacement by making a new key and washing the lock with WD-40.
Anti-theft rod jamming in any position.
If it is impossible to turn on the starter or other electrical circuits. The cause of the malfunction is a broken or burnt contact part of the wire.

Checking and replacing the contact group

To change the contacts in the lock you need to:

Remove the spring ring that secures the group in the lock body. The ring is pryed off with a thin screwdriver.
Remove the contacts from the lock.
Install a new group. When connecting, it is necessary to ensure that the groove made on the contact group coincides with the rotating rod on the secret part of the lock. The body of the contact part should fit into the slot of the body with its protrusion.

When replacing contacts, take into account the number of pins on the part. The spare parts supplied have six wiring connection points. Until 1986, a group with seven contacts was installed on VAZ 2107 cars. Instead of one pin 15, 15/1 and an additional 15/2 are used. To connect a new lock to such a car, you need to connect wires 15/1 and 15/2 into one branch.

Installation and connection of a new lock

Installation of a new or repaired lock is carried out in the following sequence:

Insert the key into position “0”.
Press in the locking latch and insert the part into the guide housing.
Install the wires using connectors or a standard plug (the connection is made in accordance with the color of the insulation).
Reinstall the mounting screws.
Install the protective cover.
Place the terminal on the battery and test the operation of the device.

When connecting the ignition switch to a VAZ 2107, you must strictly follow the electrical diagram. An incorrect connection will result in a short circuit and damage to the electrical equipment.

How to install and connect a new/repaired lock

Installation goes like this:

The key is inserted into position “0”.
Next, you need to press the latch and insert the part into the guide housing.
The wires are installed using a connector or plug (pay attention to the color of the insulation).
The mounting screws are now put back into place.
The protective casing is installed.
And finally, a terminal is put on the battery.

All that remains is to test the functioning of the lock.

Note: in a VAZ-2107 car the electrical diagram must be strictly followed. If an error occurs, a short circuit will occur and, as a result, electrical equipment will be damaged.

How to remove the ignition switch on a VAZ-2107 if it is locked?

There may be cases when the ignition switch jams and the cylinder cannot be turned either by hand or with a tool. It is possible for the key to break when part of the bit remains inside the well. In both cases, the owner needs to remove the device from the car.

First dismantling option:

Remove the steering wheel from the shaft. The steering wheel is secured with a 24 mm wrench nut, which should not be unscrewed completely. Removing the steering wheel from the splines is done by supporting the legs and striking the forearms. After removing the part from the splined part of the shaft, the nut is completely unscrewed.
Remove the protective plastic steering column cover secured with Phillips screws.
Unscrew the screws securing the lock.
Press the pressure plate with a thin tool, which will slightly unlock the part. The pressure is applied through the slot on the left side of the lock. Pressing the latch will allow you to slide the lock body towards you.
Use a hammer to hit the plate on the right to rotate the lock around its axis. This will guarantee against the retainer coming back.
Using a hammer and chisel, break the plate. Apply blows carefully so as not to damage the steering column switch block.
After removing the plate, the locking rod installed in the two eyes will become visible. One of the eyes is easily visible through the hole.
Break the eyelet with a chisel or flathead screwdriver.
Press the plate again through the slot on the left and pull it up. It should move 10-12 mm.
Using a hammer, strike the lock body (in the area where the plug is installed) and pull it off the shaft.

After the latch is recessed through the slot on the left side of the lock, you need to pull the lock out to the maximum distance.
On the right side of the lock there is a platform with text and a number. A wedge (screwdriver) is inserted under it.
After this, the area with the inscriptions is cut off with an impact screwdriver or chisel.
Use a screwdriver to push the lock pin through the hole and remove the lock from the shaft.

The third method is to destroy the castle with a sharp jerk:

One person sits in the driver's seat, the second in the passenger seat.
It is necessary to sharply jerk the steering wheel at the same time, which will cause the destruction of the clamp.
After this, the lock is removed using the usual method. It is worth noting that only late-release locks can be broken with a jerk; products from the USSR era are more difficult to break this way. In addition, there is a risk of damage to the steering components.

There are other methods for removing jammed ignition switches on a VAZ 2107 - cutting the body, turning or drilling the cylinder, and others. The final choice of dismantling method remains with the car owner.

The technique for removing a jammed device is demonstrated in a video from the “Region 4253” channel.

How to replace the ignition switch without a key?

Replacing a lock without the original key follows these steps:

Remove the plastic casing.
Use a thin screwdriver to pry off the ring with the marked key positions.
Remove the ring under which the larva will be located.
Drive a screwdriver into the gap between the cylinder and the body to loosen the fastening pin.
After the pin falls out, remove the cylinder.
A movable element is installed under the cylinder, which is pressed out when the lock is turned with a key. It must be pressed to unlock the shaft.
Remove the device from the steering column and replace it with a new one.

Methods for checking the lock from the “Autoelectrics HF” channel.

How to replace a lock if there is no key

You can do this like this:

First, remove the casing.
Next, use an awl or a thin screwdriver to pry up the ring with the possible key positions marked on it and remove it.
The larva is located underneath it. It is into the gap between it and the body that you will need to drive a screwdriver in order to loosen the fastening pin.
Afterwards, the cylinder must be removed, and the component located under it must be squeezed out in order to unlock the shaft.
Now the device can be removed from the steering wheel and replaced.

Thus, it is absolutely possible to carry out all the repair procedures yourself – there is absolutely no need to go to a workshop.

The owner of a VAZ-2107 car can change the ignition switch on his own. To do this, it is enough to have a set of simple tools and a little theoretical knowledge.

What is a VAZ-2107 lock?

The ignition switch (hereinafter referred to as the ignition switch) is the main element of the electrical system of the entire car, turning it on and off. It is located under the dashboard, on the steering column on the left. In the off position, the ZZ blocks the steering column, preventing the car from being stolen. Also, an additional means of protection is a key, which is individual for each lock.
