Replacing the door lock cylinder on a VAZ 2109. when the time has come

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 is

First, let's look at the structure of the castle. Let's find out what it looks like, what it consists of, what its operating principle is, and so on:

• As mentioned, the ignition switch is a very important element of the VAZ 2109 car, because almost all available equipment is connected to it.

Note. Although there are components that do not depend on the lock in any way. Here they are: license plate lights, brake lights, parking lights, hazard lights, interior lights and lights on the dashboard.

• There are different types of ignition switches: new or old type. The first version without a relay has three positions and a short key, the second with a relay has four positions and a long key.

Scheme

Below is a typical diagram of the ignition switch on the “nine”.

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:

1. To remove the handle, use a screwdriver to unscrew two bolts: top and bottom.
2. 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.
3. The panel is removed and the external fasteners are removed using a size 8 wrench.
4. Access to traction is gained. It can be unscrewed freely using a screwdriver.
5. The handle is removed along with the rods, the tip is dismantled.
6. The core of the cylinder device opens.
7. To change the cylinder, it is important to remove the return spring.
8. After installing the new core, we return the spring to its place. A pin is installed on the tip of the rotary rod.
9. The lubrication of the elements and the functionality of the mechanism are checked.
10. 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.

How to replace a lock

The design of the locks on the front and rear doors of the car is fundamentally the same, the difference lies in the installation of the lock switch cylinders on the external handles on the front doors. Instructions on how to replace the front door lock are presented below:

• The lower seal is pressed out, and three spring clips are removed from above to secure the protective film and one from below.
• The protective film is removed from the door.
• Inside the lock, the lock switch and external handle rods are disconnected.

Disconnection points for switch rods

Tip: During assembly, sealant was applied to the threads of the screws, so when twisting, you need to use an impact screwdriver.

• The outside door lock is removed.
• Unscrew the two screws securing the internal handle of the device.
• The handle is pushed inside the door.
• The internal lock and handle are pulled out of the doors, as shown in the photo.

• The rubber holder is removed from the end of the rod.
• The handle is removed from the rod. In this case, it needs to be cranked.
• The locking bracket is detached from the lever pin.
• The rod of the internal handle is disconnected from the internal lock lever.
• The plastic holder is rotated and the end of the rod is removed from the lever to lock the device.
• Unscrew the two nuts securing the outer handle of the lock.
• The handle is removable.
• The plastic rod end is removed from the door lock cylinder and removed.
• The locking spring is removed. To do this, its ends are removed from the slots on the lock handle and cylinder.

Removing the retaining spring

• A key is inserted into the lock cylinder and the part is removed from the handle.
• Repairs and replacement of faulty elements are carried out, or a new lock is installed.
• Assembly of the unit occurs in the reverse order.
• The lock can be adjusted if necessary. To do this, loosen the screws and move the latch:

1. outward, when the door is tightly closed;
2. inward, if the door is not closed tightly;
3. down if the door is raised when closing.

After adjusting the device, tighten the screws.

Tip: If you need to remove the retainer, you must first trace its outline on the body pillar. This will help maintain the door lock adjustment during installation.

How to install a silent lock on the door of a VAZ 2109 car

Very often you can hear an unpleasant metallic clang when closing the doors of a VAZ 2109, especially in older models. This is due to the fact that the lock is attached to the outside of the door and when closing it comes into contact with the metal parts of the body and creates a characteristic sound. Manufacturers are now producing silent locks. They are sold in pairs, left and right, their price is reasonable. If the door lock on a VAZ 2109 car is jammed, it is better to immediately replace it with a silent one. To do this you need:

Unscrew the bolts holding the old lock on the car door.

Unscrewing the fixing bolts of the old lock

• The pin is screwed into place of the unscrewed bolt, otherwise the inside of the lock may fall inside the door.
• The old lock is removed and a silent one is installed.
• The bolts are tightened with maximum force. Tighten using an impact screwdriver.
• You can also install locking pins or silent bolts.

Installation of silent bolts

Shown how to correctly replace a VAZ door lock

The installation operation ends with adjusting the locks. In this case, the position of the latch changes due to large holes in the rack. For this:

• The contours of the latch are outlined on the stand.
• When opening the doors tightly, you need to loosen the screws holding the latch, it moves outward and the screws are tightened.
• If the door does not close tightly, the latch must be moved inward.
• If the door lowers when closing, the latch must be raised and lowered when the door is raised.

Tip: In order not to disturb the adjustment of the clamp, you need to install a spacer made of waterproof sandpaper under it. Using the same spacers under the clamp, you can adjust the distance between the clamp and the stand. This is necessary so that the locking pin does not touch the cover of the external lock.

Installing a silent lock guarantees the car owner the absence of ringing and clanging.

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:

1. 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.
2. Adjusting the response part if there is no softness when closing or a squeak is heard. The door moves outward using external adjustment bolts.
3. 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.

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:

1. 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.
2. It is recommended to use silicone during lubrication.
3. 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.
