Trunk lock VAZ 2107 device

Replacing the lock

The process of dismantling the old device and installing a new one will take no more than 30 minutes. Follow these steps:

1. Trace the outline with a pencil to accurately mark the position of the mechanism on the body. 2. Using a socket wrench, unscrew the two nuts that secure the device. 3. Carefully remove the lock without scratching the body covering. 4. Use your finger to push the cylinder inside the cover and remove it along with the bushing. 5. If necessary, remove the gasket. 6. Clean the new lock from dirt and dust, lubricate all its parts. 7. Put the gasket in place. 8. Insert the new cylinder into the bushing. 9. Install them in the lock. 10. Place the assembled lock in the place marked with a pencil. 11. Tighten the mounting bolts using a 10mm socket wrench.

If the trunk is difficult to open, you need to adjust the position of the lock in relation to the latch. To do this, the mounting bolts are slightly loosened and the mechanism is slightly moved so that the latch can easily enter and be securely fixed by the lever.

To adjust the force required to open the lid, the spring torsion bars are shifted by one tooth in the hinge using the installation tool.

Typically, the VAZ 2107 trunk lock is replaced after the lid stops closing the first time or starts knocking while driving. In some cases, the trunk lock must be removed and installed in order to replace its cylinder. For example, if the key is lost or the cylinder mechanism fails. So, what is needed to replace the lock and how to do this work yourself, without turning to the services of a service station.

Button does not work

If the electric drive stops working, then, first of all, it is recommended to disassemble the button itself and try to short-circuit the wires connected to it directly.
When the trunk does not open, it means that the activator relay has failed. Usually specialists place it next to the button. Replace it with a good one.

Sometimes this doesn’t help, then you have to look for a break in the wires. Use a tester for this.

It would also be a good idea to inspect the fuses. If the lock has been lubricated for a long time, then the work of the traction overloads the electrical system of the car, and the fuse-link of the protective device may not withstand it.

When none of the above tips work, you will have to climb into the trunk through the interior by removing the rear seat, as described above.

Trunk lock device for VAZ 2107

The trunk lock of the VAZ 2107 consists of the following parts:

rotor axis;
case cover;
drive extension;
lever arm;
spring;
rotor;
frame;
retainer;
retainer plate.

A retainer with a plate is installed on the car body, with which the rotor and lock body engage. If any of the parts is damaged, it must be replaced. If it simply does not work well, but there is no visible damage, you must first try to lubricate the device and adjust the position of the lock relative to the latch on the body. If these operations do not help, the part should be replaced with a new one.

What is needed for replacement

Before changing the trunk lock of a VAZ 2107, you need to stock up on four items:

10mm wrench (preferably a socket wrench);
installation (needed to adjust the closing force of the trunk lid);
pencil;
new trunk lock for VAZ 2107.

You will also need aerosol lubricant or “Litol”.

Other options

If you don’t want to break anything, then do this:

put on a glove;
Punch your fist into the center of the license plate with all your might;
a sharp blow can knock the tongue out of the groove.

The chance of success is one in three.

The next option is a little harmful - you need to carefully pierce the rubber sealing tape that seals the trunk lid in the lock area, a little to the right. Use a thick knitting needle or a sharp knife. Insert a piece of wire with a hook at the end into the resulting hole. Use it to feel the valve and pull it to the side, pressing the lid with your free hand.

Replacing the trunk lock of a VAZ 2107

To remove the trunk lock, you must perform the following steps:

mark the position of the trunk lock with a pencil;
Using a 10mm wrench, unscrew the two bolts holding the lock on the trunk lid;

Undocking and removing the lock from the luggage compartment lid;
push the VAZ 2107 trunk lock cylinder inside the lid;
remove the cylinder together with the lock drive extension (distance sleeve);
Remove the trunk lock O-ring (if necessary).

If you are only replacing the trunk lock cylinder of a VAZ 2107, then the removed lock must be cleaned and the parts lubricated with “Litol” or aerosol lubricant. If the old lock also needs to be replaced, then it is necessary to lubricate the parts of the new lock. Once the lock is lubricated, install it as follows:

insert the sealing ring of the lock into the trunk lid;
insert the lock cylinder into the drive extension (distance sleeve);
install the cylinder with the bushing into the lock;
install the lock assembly in its regular place on the trunk lid, focusing on the pencil marks;
secure the lock with two bolts and tighten them with a 10mm wrench.

If the lock does not close well, its position relative to the latch should be adjusted. To do this, you need to loosen the fastening bolts and change its position so that the latch fits freely into the body and the lever securely fixes it, and there is a uniform gap between the trunk lid and the body around the entire perimeter. To adjust the force of opening the trunk lid, you need to use a mounting tool to move the ends of the torsion bars of the springs to one of the teeth of the trunk hinges.

This completes the replacement of the VAZ 2107 trunk lock.

The trunk of a car is a place where you can store a spare tire for a car, as well as transport various loads of appropriate sizes and weights. The trunk lock on the VAZ 2107 is designed not only to close the lid, but also to restrict access to it for unauthorized persons. Sometimes owners of Zhiguli seventh model encounter problems such as lock malfunction.

Simple ways to open a VAZ

Now let's get down to the methods. Conventionally, they can be divided into two groups: radical - when actions are decisive and not always justified, and delicate - calmer, conservative methods:

Open the door with wire

As you understand, it is better to use delicate methods, since more decisive and drastic ones will lead to the fact that you will have to pay for repairs. For example, if you break the lock to your vehicle, you will have to order it along with new keys and wait a long time until the order is fulfilled. Thus, you will not be able to use the car. Well, having broken the glass, you will have to install a new one.

Let's look at delicate methods

Method 1: Open the trunk

To open the trunk of a VAZ, you will need:

Using an open palm, strike the area below the trunk lock. The blow must be strong and sharp enough.
Take an awl (if it’s not there, then buy a nail file at the nearest stall, and you don’t have to open the trunk).
Using an awl or nail file, try to get under the door seal and press the tongue.
The door is open!

Method 2: Open the hood

You will have to crawl under the car to get the lanyard connected to the hood latch. If you can't find it, try to find it through the radiator mesh.
Mechanically press the tongue or simply pull the cable, the hood will open.
On the car battery, find the terminals with the “minus” value, click them on the mount a couple of times.
Since the body has a “minus” value, disconnecting it with the terminal will cause the doors to unlock.

How to remove the trunk lock

As soon as a problem occurs in the trunk lock, it is necessary to immediately repair it. To do this, you will need to remove the lid opening mechanism. This is done in order to repair or replace the trunk lock. The procedure for removing the trunk lock is as follows:

Initially, it is necessary to outline the outline of the mechanism, thereby indicating the position of the device on the cover. This is done so that the lock does not need to be adjusted again.
Using a key set to “10”, you need to unscrew the 2 nuts that secure the lock to the trunk.
Now you can dismantle the device from the car, and then, pushing the cylinder inside the cover, remove the core.
The core or cylinder is dismantled together with the spacer bushing.

This is interesting! Particular attention should be paid to the rubber seal, which must be replaced if worn or if there are signs of deformation.

The process is not at all difficult, and it takes no more than 15 minutes to complete. The new cylinder with the mechanism is installed in place in the reverse order of removal. You need to install a pre-lubricated lock on the trunk of a VAZ 2107, but we will learn about this in more detail later.

Replacing the cylinder and installing the trunk lock on the seven

If there is a need to replace the cylinder, then before installing a new device, it must be thoroughly treated with Litol-24 lubricant. Lubrication must be applied not only when installing new parts, but also after repairing old components.

Replacing the VAZ 2107 lock cylinder should be done in the following order:

First install the sealing rubber into the trunk lid. Moreover, it is advisable to replace it if there is excessive wear.
A cylinder must be installed inside the spacer bushing.
Together with the bushing, the cylinder must be installed in the lock (mechanism).
Position the mechanism in the trunk lid, matching it exactly with the marks that were previously marked with a marker.
As a result, you will need to tighten the fastening nuts using a wrench.

At this point, the process of replacing the larva is completed, and you can continue to operate it further. After installation, it is recommended to use liquid silicone grease, which is applied inside the cylinder to lubricate the mechanism.

Adjusting the trunk lock

Often, owners of sevens encounter difficulties when opening the trunk lid. Moreover, they are directly related to the fact that the mechanism jams due to a violation of the location on the lid. The setup process is quite simple:

Loosen the fastening nuts.
Move the device higher or lower depending on the reason why the trunk cannot be opened.
Secure the nut by hand and then tighten it with a wrench.

As a result, it is necessary to check the quality of the device. If there is a gap (between the lid and the trunk walls), jamming, or the device jams when opening, you still need to adjust it. As soon as the mechanism is working properly, you need to mark the position of the lock with a pencil, which will allow you to install it in place the first time next time.

Opening with a button

The ability to open the trunk lid remotely makes the domestic car more comfortable. In this case, there is no need to constantly unlock the lock with a key, since it will open automatically with a button. In addition, such a device will eliminate the development of situations when the lock freezes, and it can only be opened after pouring hot water on it. Making an electric lock on the seven is not difficult, and for this you will need to take the following parts:

Relay with four contacts.
Activator or electric drive.
Wires and button.
Female and male connectors for connecting the circuit.

You will also need electrical tape or heat shrink tubing. Before you start work, you will need to remove the negative terminal from the battery. The principle of implementing the idea is carried out in the following simple way:

It is necessary to supply power from the battery to the relay terminal in accordance with the diagram. Both contacts “87” and “85” must be powered directly from the battery, which will allow you to open the cover even when the ignition is turned off.
From contact “86”, run a wire to one of the button terminals. The second pin of the button must be connected to ground on the car.
From contact “30” of the relay you need to power the activator by applying power to the green wire.
Connect the blue wire from the activator to ground.
Check that the system is working properly.

The activator must accordingly be secured to the trunk lid so that when the armature moves, the lock is affected. As a result, the electric drive for the trunk lock on the VAZ 2107 will be connected and begin to work flawlessly. The button in the cabin is located directly on the panel so that at any time, without leaving the cabin, you can press it and open the lid.

Exiting the trunk lock cable to the passenger compartment

An electric drive for opening the trunk lid is more efficient, however, this method is more expensive than using a cable. The operating principle of the cable is similar to opening the hood. You just need to use a cable several times longer.

To make your idea a reality, you will need the following material:

A cable whose length is 4 m and also has a diameter of 1.2 mm.
Braid of appropriate length that can be used from a bicycle.
Heads for cable.

In order to use the cable to open the trunk lock, it must be routed from the driver's seat to the trunk lid. In this case, a corresponding lever is installed near the driver’s seat, and the second end of the cable must be secured to the movable element of the trunk lock mechanism of the VAZ 2107.

At this point, the process of upgrading the opening of the lock is completed, and you can test its operation. Practice shows that it is easier to install an electric drive to unlock the trunk than to lay a braided cable.

How to get to the salon

Gaining access to the interior of a VAZ-2107 will not be difficult, since additional security systems are usually not installed on this car. To gain access to the interior, you can use wire or fishing line. Let's look at each option in detail:

In the VAZ-2107, standard buttons with a larger diameter “cap” are installed on the doors. They are the ones who can help get rid of the problem of a locked door. Find a fishing line or thin rope that is long enough that you can make a loop in it and still have about 1.5 meters left. The loop should be in the center of the fishing line so that you can tighten it by the loose ends. There is a small gap in the upper left corner of the door through which you can push the fishing line inside the cabin. If it is too small, then take a wooden wedge and widen the opening. Next, all you need is sleight of hand - you need to hook the bolt by the upper part with a loop, tighten the fishing line, after which all you have to do is pull up to lift it.
The second option is to make a special tool from wire. Take a piece of thick wire that will hold its shape well. Its length should be equal to the height of the door. You can take it a little longer, about 3-4 centimeters, to make a hook bent at 45 degrees. Carefully inspect the door; you need to find the place where the edge of the rubber seal is located (between the window and the door body). Bend the seal to get inside the door. A couple of centimeters of free space is enough to lower the wire. It should collide with the locking mechanism, which you need to go around and plunge the rod below. After this, move the wire to the center and feel the lock lever with the hook, pull it up.

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.

Mechanism design

The lock on the trunk is arranged as follows:

READ Replacing the front brake hose of VAZ 2107

A clamp and a plate are attached to the body. The lock body and rotor engage with them.

If any part is damaged, it is easy to replace it with a new one. If there is no visible damage, you can simply use lubricant and adjust the distance between the latch and the lock. If none of this helps, you will have to install a new device.
