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.

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.

How to properly replace door hinges.

The repairs made, of course, depend on the cause of the sagging and the condition of the hinges. If the driver's door is sagging due to worn-out hinges, then you can replace the axle (if the hinges themselves are in good condition), but it is still safer to replace the entire set, since the entire structure is subject to wear.

To replace door hinges you need to do the following:

• First, remove the driver's door;
• then the loops are cut off, since they are welded;
• to remove all the remnants of the loop, you need to drill them out;
• To install a new hinge, you need to make (drill) a hole on the side for a bolt, which after installation will need to be trimmed with a grinder.

After the replacement has been made, it is very important to make adjustments following the algorithm:

1. To facilitate adjustment, the mating part of the lock is dismantled;
2. The correct position of the car door along the vertical axis is determined. To do this, it is closed and the offsets are determined. We can eliminate this defect by loosening the door hinges and then raising (or lowering) the doors;
3. The fasteners are tightened well and the location relative to the opening is checked. If the end part is shifted downwards, the lower fastening is released. After this, using thin metal plates, achieve the normal position of the door, placing them under the hinge. If, on the contrary, the edge of the door is raised, the same thing is done only with respect to the top hinge.
4. Horizontal position is adjustable. If the door is too recessed into the interior, the hinges move closer to the edge. Otherwise (when the door protrudes outward), the hinges are moved inside the car. This process needs to be given special attention, since a violation of the horizontal position can cause the door to jam due to improper functioning of the lock.
5. After the doors are correctly aligned, the mechanical lock and its counterpart are adjusted.

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.
