Replacement of all door locks on VAZ 2108, VAZ 2109, VAZ 21099

Many problems of VAZ cars are related to the functioning and operation of doors. The inability to open the door causes discomfort for both the driver and passengers. It is a particular nuisance for the motorist if the lock, particularly the cylinder, breaks down on the front door, and even on the driver’s side.

It is known that the lock cylinder (cylinder) is a security mechanism that protects the car from unauthorized access and penetration, so replacing the cylinder requires an urgent decision, and many drivers are interested in how to do it themselves.

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.

Causes of failure

The door lock cylinder on a VAZ 2109 is replaced in the event of a malfunction. We list the most common reasons:

• Lost key;
• The latch that secures the lock itself to the rod connecting it to the central lock has fallen off;
• Breakage specifically of the larvae. Due to the design features, it cannot be repaired, only replaced;

• Broken wire.

In any of these cases, the lock will have to be disassembled. Don't delay this. Timely repairs will save you from hassle and preserve your property.

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.

What you need to prepare for work

The replacement itself is not particularly difficult, but it will require a lot of tools.

• screwdrivers - flat, Phillips and impact;
• 8mm head;
• pliers;
• medium weight hammer;
• wrench or ratchet.

Of course, you will also need a working cylinder, as well as lubricant. For the latter, a silicone-based composition is ideal.

Having prepared all of the above, you can get to work.

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.

Changing the contact group

From a cost point of view, replacing one contact group is the least expensive:

• All our actions are repeated in principle, as in the case described above with removing the lock, you will have to remove the casing, and so on
• To avoid the common nuisance associated with mixing up contacts, it is recommended to number them (or otherwise mark them) before disconnecting them.
• This measure will save your nerves and time
• Some models of locks have a locking ring in their contact group, and here we need an awl to remove it
• It’s important not to forget to put it back in place later.
• Then everything is assembled back and screwed to the steering column

That's all, all that remains is to finish watching the video and calmly change any part of the lock.

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.

What problems arise with doors

When might it be necessary to adjust the doors of a VAZ 2107? This happens in cases where the locking mechanism refuses to function. The inoperability of the locking mechanism is manifested by jamming of the doors, while they cannot be either closed or opened.

It is important to know! Reviews from owners of "Sevens" show that the most common disease of VAZs is door misalignment (sagging). When skewed, they close very poorly and are difficult to open, so it is urgent to take appropriate action to eliminate the malfunction

There are also cases when faulty locks allow doors to open while the car is moving. Over time, any parts wear out, and with frequent and careless use, the locks can fail at any moment. To correct the situation, it is necessary to periodically diagnose the door locks on the “seven”. Diagnostics consists of checking, lubricating and adjusting the locks of all devices on a VAZ 2107 car

Let’s find out in more detail how to adjust, as well as what details you should pay attention to.

Features of adjusting the gap and hinges

Adjustment does not require special knowledge, but it will require enough time to accurately set the locks, hinges and gaps

Initially, you should pay attention to the lock mechanisms, as well as diagnose the condition of the gaps between body panels, front fenders, as well as racks and frames. We also recommend that before starting work with the adjustment, thoroughly clean and lubricate the lock mechanism and the mating part; sometimes this solves the problem of poor closing and further work becomes unnecessary

The gaps on the VAZ-2107 car sometimes reach 7 mm, which, by the way, is not a rare occurrence. If you cannot set a stable gap (no more than 3 mm), then there is nothing to do, you should proceed to the stage of adjusting the hinges.

In order to adjust the hinges on the VAZ-2107, you need to use a Phillips impact screwdriver. The hinges are adjustable either in pairs or only one, which depends on where the door is skewed

When adjusting them, you need to pay attention to the condition of the seals; if they no longer perform their functions, they need to be replaced. When adjusting the hinges, it is recommended to lubricate them and also eliminate any play.

Features of lock adjustment

It is necessary to begin adjusting the door locks of the VAZ-2107 with troubleshooting. To do this, you should initially inspect the mechanism, and then lubricate the crossbars. There are two options for adjusting the locks on the “seven”. Let's consider both options:

• Option #1. Before adjusting the doors, you need to make sure that the parts of the product do not have critical wear. The front and rear locks have a similar design, so the adjustments are identical for them. It is necessary to begin work by unscrewing the three bolts that secure the mating part of the lock located on the rack. Once the bolts are loosened, you can proceed. To do this, the mating part should be visually positioned so as to obtain the optimal position. Afterwards, it should be slightly tightened and checked; if the door does not close, then it is necessary to slightly lower or raise the position of the counter part. If the closed door protrudes, we move the counter part inside the car; if it falls inside, we push it out. It is necessary to adjust little by little, until the most optimal moment.
• Option #2. How to adjust the door lock on a VAZ 2107? To do this, you need to slightly loosen the three bolts that secure the mating part. After loosening them, you need to close the door and lightly press on it. After this, the product must be opened and the bolts tightened. We repeat the closing again, and if necessary, the mating part is shifted again.
• If, after prolonged manipulation, it ends with the impossibility of adjusting the door lock, then you may have to replace the hinges. In most cases, problems arise with the hinges, which wear out and sag over time.

Adjusting door locks.
Before carrying out work, you can use a pencil to outline the contour of the mating part. The original location of the product should be used as a starting point when carrying out adjustment work using any of the options described above.

Adjustment is not particularly difficult, but requires special precision, so be patient and get to work. If you still cannot adjust the locks on your car acceptable, go to the nearest auto body repair shop and they will help you.

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:

1. The handle unscrews. The trim, trim, and panel are removed.
2. The two dome lamp terminal connectors, the windshield wiper motor and the actuator are disconnected.
3. The lock is removed using pliers. The rods are turned off and the spring is removed.
4. A new mechanism is inserted. The spring returns to its place.
5. 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.

How can you tell if a car door is sagging?

1. Significant force must be applied to close or open the door.

2. When the car moves over uneven surfaces, a characteristic knocking or rattling noise comes from the door.

3. If the door is skewed relative to the body or doorway, water may leak into the interior through a poorly fitting seal.

4. Characteristic scratches appeared on the sills.

Common causes of sagging doors.

1. Significant wear on the hinges and axles.

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.
