Replacing the door lock cylinder of a VAZ 2109 - how to change the rear door opening rod

Door lock device

To understand how to change the door lock on a VAZ, it is important to understand the structure of the mechanism itself. The larva is a metal core that is activated when the key is turned in the well. Protection is provided by locking the internal teeth. If incorrect operation of the locking system is noticed, the entire lock or its cylindrical part is replaced. When the key enters the device, the internal pins begin to move. When problems arise when opening/closing the mechanism, it means that the teeth do not fit into the grooves.

If the pins diverge in different directions when opening, then when closing, a disconnective displacement occurs. This encoding is activated when the key is turned. The reasons for the breakdown may be as follows:

creak;
difficulties when inserting and removing the opening object;
jamming;
internal or external damage to the cylinder;
The key does not go all the way into the hole.

When the lock is used for a long time, parts wear out. In order not to completely change the closing device, you can remove the cylinders and install a new one.

What can happen to the ignition switch

Most often, the ignition switch itself, the contact group or the locking mechanism can break down. Each breakdown has its own differences:

If, when inserting the key into the cylinder, you notice some difficulties when entering, or the core does not turn well enough, then you should conclude that the lock has become faulty.
If you cannot unlock the steering shaft in the first position, there is a breakdown in the locking mechanism.
If there are no problems in the lock, but the ignition does not turn on, or, on the contrary, it turns on, but the starter does not work, then the fault must be looked for in the contact group itself.
If the cylinder fails, then a complete replacement of the lock is necessary; if the contact unit is broken, then it can be replaced without the cylinder. Although today it is much better and much cheaper to completely replace it than to repair the old ignition switch.

As a result of all of the above, I would like to say that the ignition switch is one of the most reliable parts in a car, but it also tends to break. The most common breakdowns that can be encountered are jamming of the cylinder or its general wear, corrosion of the contacts, or mechanical damage to the contact unit. All these parts require careful care and timely diagnostics in order to avoid serious malfunctions. And if you didn’t manage to “outsmart fate,” then in order to cope with its repair yourself, you must know the structure of the ignition switch and the principle of its operation.

Tools

To repair or replace a car lock, you need to prepare:

flat-head and Phillips-head screwdrivers;
pliers;
socket wrench 8;
silicone grease;
larva

If desired, you can immediately replace the standard part with a European pen, which is purchased in advance.

Repair work is carried out in a well-lit room and at a comfortable temperature.

Repair or dismantling of interior door locks

When replacing the rear door lock of a VAZ 2109, it is important to follow the algorithm of actions:

To remove the handle, use a screwdriver to unscrew two bolts: top and bottom.
The cover, plug and casing are removed. The facing material is secured with special latches. It is important to dismantle them carefully so that the plastic elements do not break.
The panel is removed and the external fasteners are removed using a size 8 wrench.
Access to traction is gained. It can be unscrewed freely using a screwdriver.
The handle is removed along with the rods, the tip is dismantled.
The core of the cylinder device opens.
To change the cylinder, it is important to remove the return spring.
After installing the new core, we return the spring to its place. A pin is installed on the tip of the rotary rod.
The lubrication of the elements and the functionality of the mechanism are checked.
The assembly is performed using the reverse algorithm.

Sometimes it is necessary to replace the wires that are connected to the lock. If a small break is detected, the electrical wiring is partially changed.

6) To complete the operation, insert the door opening key into the cylinder, and then remove the cylinder from the handle.

Replacement of external and internal door lock:

Replacing an external door lock: 1) In order to remove the external lock from a car door, read a separate article on this matter, published earlier on our website, the article is called: “Replacing an external lock”

Replacing the inner door lock: 1) First, use a screwdriver to remove both screws that secure the outer lock to the car door.

Note! It is best to unscrew these two screws with an impact screwdriver, but if you don’t have one, then use a regular screwdriver! (If you do not know about such a screwdriver or do not know how to use it, then look at the article entitled: “What is an impact screwdriver and how should it be used?”)

2) After unscrewing the screws, remove the outside lock from the car door.

3) Next, unscrew in exactly the same way as the central screw, two more screws that secure the clamp, and then remove the clamp from the car body.

Note! Before removing the latch, we recommend that you circle the place where the latch was installed with a felt-tip pen, so that when you reinstall the latch, the adjustment of the door lock is not disturbed!

Important! 1) Reinstallation of the latch, cylinder, as well as locks and all handles occurs in the reverse order of removal!

Features of door adjustment

Incorrect operation of the lock may be caused by problems with the door card. After long-term use, it sags, and sometimes it is simply installed incorrectly. Basic actions:

The lock latch, which is located on the stand, is adjustable. To do this you will need an impact screwdriver. The screws are first loosened, adjustments are made, then the fasteners are tightened.
Adjusting the response part if there is no softness when closing or a squeak is heard. The door moves outward using external adjustment bolts.
The bracket is dismantled using a hammer. After several blows the door moves. After this, the operation of the mechanism is checked. If the problem does not go away, the procedure is repeated.

Replacing and adjusting the trunk lock

The luggage compartment is equipped with an identical lock as the driver's door. For dismantling you will need a standard set of equipment. Step-by-step instruction:

The handle unscrews. The trim, trim, and panel are removed.
The two dome lamp terminal connectors, the windshield wiper motor and the actuator are disconnected.
The lock is removed using pliers. The rods are turned off and the spring is removed.
A new mechanism is inserted. The spring returns to its place.
The rod is screwed on. Electronics are connected.

The price of a complete set of locks for the driver's door and trunk starts from 500 rubles.

Recommendations for changing the cylinder in a VAZ 2109 lock

If you disassemble the core, you can avoid replacing the cylinder or the entire mechanism. When the door opens with a creak, then most likely the internal pins are not deformed. Then lubrication work is carried out and the serviceability of the device is checked. Tips from the experts:

Partial repairs will bring life back to the castle for a short period of time. If serious problems arise, it is better to immediately replace the larva.
It is recommended to use silicone during lubrication.
When dismantling, you will need a set of screwdrivers: flat, Phillips, impact.

Experts advise purchasing clips in advance that hold the casing and spring, since during dismantling these parts most often become unusable.
