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.

Trunk lock device for VAZ 2107

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

1. rotor axis;

   

2. case cover;
3. drive extension;
4. lever arm;
5. spring;
6. rotor;
7. frame;
8. retainer;
9. 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”.

Mechanism design

The lock on the trunk is arranged as follows:

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.

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.

How to open the trunk of a VAZ classic without a key

How the trunk lock on the VAZ 2107 works and what it is is already known. It remains to figure out the question of how to open the trunk of a VAZ 2107 without a key, since you often have to deal with the need to dismantle the device.

READ What kind of gas is in the stove at home?

If the rear compartment lid slams shut, you will need to use a spare set of keys to access the compartment. If you cannot find the keys, then there is an option to contact specialists who will help you open the device within 5 minutes. However, for these five minutes you will need to pay a lot of money, and besides this, you still need to find a good specialist.

If the key is left in the luggage compartment, you can get to it from the passenger compartment. To do this you need to do the following:

• From the interior, disassemble the back of the rear seat, for which you just need to dismantle the back.
• Remove the fiberboard stand to create a gap through which you can get to the keys in the compartment.
• To do this, you need to use a hook made of steel wire of the appropriate length to reach the key, hook it and remove it.

This is the easiest and most painless way to open the lid without deforming the car.

If the key is lost, then there is no point in getting into the luggage compartment. To do this, it is recommended to take a powerful flat screwdriver (one with a blade instead of a key in the cylinder), insert it into the cylinder (maybe hammer it in there a little) and forcefully turn it towards opening the lock. But this option should be used as a last resort, since the larva will then be unsuitable for use.

There are also such ways to open the trunk lid:

• Tap your fist on the location of the license plate. This barbaric method helps in 30% of cases. It all depends on the force of the impact, so if you are tired of trying to open the trunk lid, then use this method.
• Use an awl or knife to pierce the rubber seal. Try to reach the lock tongue through the rubber seal, and by sliding it to the side, open the trunk lid.
• Try using any other key (from another car, house, garage) that is suitable in size. There are times when this works.

Which option is better depends on the situation. In any case, coping with such a problem will not be difficult. To make sure you don’t have to try to open the trunk on the seven, you should regularly monitor the quality of the mechanism, apply lubricant and change the cylinder.

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:

1. 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.
2. Using a key set to “10”, you need to unscrew the 2 nuts that secure the lock to the trunk.
3. Now you can dismantle the device from the car, and then, pushing the cylinder inside the cover, remove the core.
4. 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:

1. First install the sealing rubber into the trunk lid. Moreover, it is advisable to replace it if there is excessive wear.
2. A cylinder must be installed inside the spacer bushing.
3. Together with the bushing, the cylinder must be installed in the lock (mechanism).
4. Position the mechanism in the trunk lid, matching it exactly with the marks that were previously marked with a marker.
5. 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:

1. Relay with four contacts.
2. Activator or electric drive.
3. Wires and button.
4. 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:

1. 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.
2. 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.
3. From contact “30” of the relay you need to power the activator by applying power to the green wire.
4. Connect the blue wire from the activator to ground.
5. 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.
