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.

Second option

If the key is lost or broken, when a part remains in the well, the option described above, of course, is not suitable. How to get to the depths of the trunk of the 2107 model in such a situation?

We'll have to act more radically. You will need a strong screwdriver (regular flathead) with a wide tip. Press (or hammer) the end directly into the cylinder. After this, forcefully turn the latter in the desired direction. Remember, after such a barbaric opening, the core will probably have to be changed.

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”.

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.

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;

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.

What to do

Like any other passenger car, the VAZ model 2107 is equipped with a storage compartment located in the rear of the body. The lid, locked with a separate lock, protects its contents from bad weather, prying eyes and the criminal element. Accordingly, it is difficult to open it without a key.

The locking mechanism of the VAZ-2107 is structurally simple. Of course, any professional burglar can easily get into the trunk if he needs anything there. The owner of a VAZ-2107, who has lost the key, will fumble for a long time, not understanding where to start.

There is no need to panic. Better remember if you have a spare set at home. If there is, then it’s better to go get it. It’s easier to open anything with your own key than with improvised means.

It’s another matter when the trunk slams shut and the bundle remains inside. So you won't be able to leave. In large cities, the situation will be corrected by contacting a company specializing in hacking. Professionals will open the rear compartment of a VAZ-2107 in a couple of minutes, but they will have to pay.

If the cabin is open, then calm down - you can save money by climbing into the luggage compartment from there.

First of all, pull out the rear sofa 2107. Dismantling is not difficult - the seat is attached to two clamps, and the backrest is held in place at the top by plates inserted into the shelf, and from the bottom by wire loops.

Proceed in the following order:

open the door and, holding the pillow frame, sharply pull it up;
do the same with the opposite side;
remove the seat;
then use a screwdriver to bend the fasteners from the bottom of the backrest;
lift it, release the hinges and pull out the top plates;
remove the element from the interior.

Now you need to remove the plywood insert - it covers the gap above the trunk. After this you will easily get to the keys. If they are far away, then use, for example, a wire hook. Next, all that remains is to unlock the lid from the outside. This method is the most gentle, but it is not suitable in all cases.

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.

Connecting the product

Before carrying out connection work, you should definitely discard the negative terminal from the battery.
To begin with, we present the scheme according to which the product will work. The electric lock will be supplied with 12V power directly from the battery, although you can also use a wire from the cigarette lighter. First, connect the wire to the “” terminal of the battery.

The battery supplies power to the relay, which can be located both in the cabin and in the engine compartment, which will be even more rational. From terminal “86” the wire is fed to the trunk opening button, which can be located in any comfortable place on the dashboard. To install the button used to open the trunk lid, you will need to drill a hole of the appropriate diameter in the dashboard.

The wire from the relay terminal “30” is laid through the cabin to the activator. Its length must be more than 5 meters. The wire can be laid together with standard wiring. This wire must be connected to the greenish wire of the activator using female-male connectors. The blue wire must be short-circuited to vehicle ground. Now you can check how the electric trunk lock of the VAZ 2107 works. It is enough to devote 2-3 hours of time so that the trunk will eventually open from the button of the VAZ 2107. After finishing the work, do not forget to connect the negative terminal to the battery.
