VAZ 2107 trunk lock, device, automatic opening

Trunk lock device

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.

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.

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.

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.

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.

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.

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:

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.

Greetings to all lovers of disgusting Lada cars! I finally got around to seeing why the trunk can be opened not only with a key, but also with any other object, and also lubricated from the inside to prevent freezing in winter. To do this, it was necessary to remove the lock from the trunk and pull out the cylinder from it. Next we proceed to disassembly. Remove the spring and push the cylinder out of the lock holder.

Next, remove the nickel-plated trim from the cylinder. To do this, carefully bend the antennae on both sides and tighten it. Underneath there are 2 springs and a keyhole flap, as well as a bunch of dirt.

The reason why the lock could be opened by anything was that a lot of dirt was packed into the grooves and the secrets were lodged in them. We begin to wash/soak the larva with a bucket/kerosene/gasoline (underline as appropriate). And we achieve normal operation of the secrets. Then we assemble everything in the reverse order, rubbing it with a very thin layer of graphite lubricant. That's basically it. The lock's functionality has been restored. Freezing in winter is prevented. The result was achieved))))) About half an hour was spent. I was surprised that the nickel from the factory clip had not come off anywhere! and did not darken, but shone like a mirror. They knew how to do quality work.

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.

What is needed for replacement

Before changing 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”.

Installation of the activator

Initially, it is necessary to install an activator, which is an electric drive that works to retract or repel, depending on the connection. The first step is to remove the lock and install the activator rod. To remove the lock, you will need to unscrew two nuts.

After this, you need to drill a hole in the side of the lock to insert the rod and connect it to the lock tongue. The rod will need to be bent (secured), it should look something like the one shown in the photo below.

After fixing the rod to the lock, the latter can be installed in place. It is advisable to remember the tilt level of the lock and install it as well, so that you do not have to adjust it during installation. Now you can attach the activator to the trunk. To do this, you will need 2 self-tapping screws and a special plate, which comes with the product. After this, you can manually try to see if the lock will work when opening. When the activator is installed on your VAZ 2107 car, you can proceed to the next stage - connection.

Connecting the product

Before carrying out connection work, be sure to disconnect the negative terminal from the battery. To begin with, we present the diagram according to which the product will function.

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 much more rational. From terminal “86” the wire is fed to the trunk opening button, which can be located in any convenient place on the dashboard. To install the button that will 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 at least 5 meters. The wire can be laid together with the standard wiring. This wire must be connected to the green 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 functions. It is enough to spend 2-3 hours so that the trunk will eventually open using the VAZ 2107 button. After completing the work, do not forget to connect the negative terminal to the battery.

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.

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:

1. From the interior, disassemble the back of the rear seat, for which you just need to dismantle the back.
2. Remove the fiberboard stand to create a gap through which you can get to the keys in the compartment.
3. 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:

1. 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.
2. 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.
3. 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.

Roof rack VAZ 2107

If the “seven” is often used to transport various cargoes, then, as a rule, the standard trunk is not enough. In this case, it is convenient to use a special roof rack. Oversized cargo can be secured on this structure. Before choosing a product, you need to find out the dimensions of the elements that can be placed on the trunk. Long materials such as boards, sticks, pipes, if their length is up to 4.5 meters, may not be marked with red flags. If the cargo exceeds the dimensions of the vehicle, i.e. protrudes beyond the front and rear bumpers, it must be marked with special red flags that inform other road users about the transportation of oversized cargo.

What types of luggage racks are there?

On the roof of the VAZ 2107 you can install a roof rack of both the old type and the modern type. The standard “Zhigulevsky” trunk has dimensions of 1300*1050*215 mm, and its load capacity is up to 50 kg. This structure is fastened to the roof gutters using bolts. In general, roof racks can be divided into 3 groups:

• open;
• closed;
• in the form of racks.

The first option is universal. The product consists of transversely and longitudinally directed metal beams with a square or round profile.

The classic type trunk consists of a metal frame that ensures structural strength and reliability of fastening

The closed trunk is a trunk (box). The main advantage of this design is the protection of the transported cargo from bad weather.

The trunk in the form of a box allows you to protect the transported cargo from bad weather

The product, made in the form of racks, is used for transporting bicycles and other equipment. This design is used less frequently, but the load can be fixed on it easily and reliably.

A roof rack made of racks and crossbars allows you to easily and securely secure the load.

Which manufacturer to choose

There are many manufacturers of roof racks for the VAZ 2107 on the Russian market. The most popular companies include: Mamont (Russia), Golitsyno (Russia), BelAZ (Belarus), Inter (Russia). The price range of products ranges from 640 rubles. up to 3200 rub.

How to install

Structurally, the roof of the “seven” has storm drains to which the trunk racks are attached. The installation of the structure for transporting luggage on the roof of the VAZ 2107 should be carried out at the same distance from the front and rear windows. Thus, the load on the upper part of the body and the pillars is distributed evenly. The rack fastenings are placed so that they do not create an obstacle to the doors when they open and close. On the Lada seventh model of recent years of production, there are special marks in the interior that indicate where the A-pillars are located. This makes it easier to install the product on the roof and position it.

When installing a roof rack, you need to ensure its positioning and install it in such a way as not to interfere with the doors

Before tightening the racks, you need to make sure that they are parallel to each other without distortion. If an installation error occurs, the roof surface may be damaged. After installing the racks, tighten the fasteners tightly so that the rubber elements are pressed well against the roof gutters. Having secured the luggage structure to the body, the product is considered ready for use. The main thing is to ensure that the load is securely secured, which will prevent its loss during sudden braking or maneuvers.

Today, a car trunk is increasingly used for its intended purpose, and in order to make its operation more convenient, you need to take care of the appropriate preparation. In the luggage compartment of the VAZ 2107, many people make a raised floor where the necessary things and tools are located. This kind of work is easy to do with your own hands, because it requires a minimum of tools and materials. Thus, it is possible to improve the condition of the luggage compartment and increase its functionality, which will ensure ease of use of the vehicle.

Optimizing space in the seven

It is not at all necessary to have an apiary for twelve hives or a serious homestead, so that sometimes you need to transport a fairly large load or a lot of small items. Situations are different, and especially when going on a trip in a VAZ 2107, not everyone wants to burden themselves with a trailer. This is why there are additional luggage racks.

But first, let’s deal with the standard, ordinary trunk of the seven. It is far from the ideal of rational distribution of space, in fact, as in all classic Zhiguli cars. The side members, wheel arches, niches, gas tank and rear suspension cups form a kind of labyrinth for dumping all sorts of rubbish. Only the size of the trunk of a VAZ 2107 is quite difficult to measure with a tape measure. It turns out to be an intricate figure, however, there are heroes who did it. The photo shows the dimensions and geometry of the trunk.

Drawings and dimensions of the false floor in the trunk of a VAZ 2107

Based on its geometry, the niche between the side members begs for a kind of organizer for tools, spare parts and small items, which you can easily assemble with your own hands from chipboard or pressed plywood. The cover of this organizer will be a false floor. The result is two independent compartments - one for hardware, the second for luggage.

The design is quite simple to assemble. For assembly, you will need to cut five blanks (or more, depending on the desired number of niches under the raised floor):

• 580x115 mm - three pieces, two of them will lie along the side members, and one will be a partition in the center;
• 780x115 mm - will fit between the rear bumper mounting pipes;
• 840x115 mm - the farthest side, between the thrust cups of the springs.

The structure is screwed together using furniture screws; the false floor itself, the size of the cover of the first tier, will be the same as the dimensions and contours of the perimeter of the resulting niche.

It is better to screw the hinges to it not in place, but by fixing the lid with several screws and removing the entire structure from the trunk, in a convenient place, on a workbench, for example. After this, you can sheathe the resulting organizer with any material - from leatherette to carpet. As a result, the trunk is always tidy, the floor is level and clean.
