The hood lock is removed if it is necessary to replace the cable or the entire lock, as well as when the hood opening mechanism interferes with various painting jobs, replacing the lid, etc. How to remove and adjust the hood lock for a VAZ 2107?
To remove the hood lock, you need to use a screwdriver and a 10mm wrench. In addition, you will need a marker or pencil, which should be used to outline the outline of the lock for ease of reinstallation or when completely replacing the mechanism. When the outline is drawn, use a standard screwdriver to pry the locking cable clamps and remove them from their seats. Now slightly straighten the cable and remove the retaining sleeve, and then remove the cable from the mechanism. Using a wrench, unscrew the two nuts that secure the lock to the hood along with the washers.
After this, straighten the rod and remove the fixing tube. In the interior, under the dashboard, pull the sheathed cable into the lock drive hole using pliers. Removing the traction mechanism using the described method is only possible if the linkage breaks on the side of the handle in the car interior. If the cable breaks in the hood area, then you will need to crawl under the hood to pull the lock spring towards the battery.
It is also worth saying a few words about the locking cables on the VAZ 2107 and other “classics”. There are single-core and multi-core rods, which differ in strength. We recommend purchasing a multi-strand cable (cost up to 150 rubles).
Tensioning the cable and installing the lock occurs in the reverse order. Use the contour that was marked during removal; you can use it to adjust the position of the lock.
On some Lada models, including the VAZ 2107, you can install an additional electric drive for the trunk lock with the button located in the car interior.
Trunk lock device for VAZ 2107
The trunk lock of the VAZ 2107 consists of the following parts:
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”.
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.
Replacing the trunk lock of a VAZ 2107
To remove the trunk lock, you must perform the following steps:
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.
In order to open the trunk with a button, we need the following:
Electric drive for the lock with accessories, all of them come with it! Be sure to check the package, they tried to push the lock onto me without fasteners (like they forgot to put it in), but then the installation process becomes more complicated :) We also need an ordinary relay (4 or 5 contact does not matter, we only need 4 of them):
VAZ relay and a couple more meters of wire, female connectors and, ideally, a “chip” for the relay, but you can do without it :) So, initially the task was to decide where to place the electric drive - I didn’t reinvent the wheel and placed it like this: And secured it through the bar with self-tapping screws: Ideally, of course, you can and should also screw in the second bar, but I was too lazy, and the lock fit tightly with its protruding end into the hole in the trunk lid (this hole even had to be widened a little with pliers) and out of the way it is impossible to move it by hand :) Next, the task was to make a mechanical connection between the electric drive and the trunk lock. After surfing the Internet, I took the simple route - without welding or disassembling the lock. We look at the photo, under the photo there is a description :) So, with a hacksaw we make cuts for metal, as shown in the photo, we bend the “tongue” that appeared as a result of these manipulations, and we have access to the lock element, by pulling which the lid will open :) Then we take the pulley that came with the electric drive, measure it in length, bend it in such a way that the electric drive has the ability to pull it into itself to open the lock, bite off the excess (saw off, break off). Looking ahead, I will say that during operation I encountered a problem that after opening the lock with a button, this pulley did not allow the lock to close, each time I had to use the handles to push it back a little - this problem was solved with the help of a return spring (the spring is like on the drive to the carburetor ) see photo, spring engagement points are circled in red:
But there is a second option, which is to put a regular spring under the rubber boot on the central locking under which it will not be visible.
The trunk lock on a VAZ 2107, like any mechanism, tends to fail over time. As a result, the lid does not fix well and knocks during the trip. Replacement is not the only reason why you sometimes have to remove the lock. The key may be lost or the cylinder mechanism may break. Let's look at how to carry out repairs yourself without visiting a service station.
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.
If the trunk lock of the 2107 Lada is very old and holds weakly, then try pressing the tongue with a metal strip, a credit card or a ruler. Be careful - these improvised master keys often get stuck in the groove of the lid.
Some experienced motorists give the following advice:
- lift the cover on the right side;
- push it to the left as hard as you can;
- pull up sharply.
When the key is simply lost, then try using any other one at hand. If it’s tight, don’t push it in completely, so as not to lose it too. Dip literally half a centimeter into the larva and try to turn it. You don't have to use any force, but be sure to press down on the top of the lid.
Sometimes a piece of the key remains sticking out of the VAZ-2107 well. Grab it with pliers and twist it in the unlocking direction - this will certainly help.
Try all the methods described - one of them will most likely work.
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.
For a whole year I was planning to make an electric trunk lock for a VAZ 2107. And then one fine day, when I finally got tired of every time I need to get into the trunk, pull the keys out of the lock, open the trunk, then stick it back again, and if I also need to turn it off, I finally got around to doing it. The door lock activator, which is used in central locks and alarms, was already lying around waiting. I didn’t even have to buy it, although the price was not more than 200 rubles.
If I had asked on the Internet how to install an electric trunk lock on a VAZ 2107, I might have done it differently, but it turned out not bad either. The installation of the electric lock is almost the same on one side, but the traction is done differently, with a cable or wire. Some install a solenoid to unlock the trunk.
There were difficulties in resolving the issue of attaching the rod to the trunk lock. I decided to make a pin and attach it to it. Drilling and threading, but it was not possible because the metal turned out to be very hard. After thinking, I decided to weld the bolt 4 by welding. Even though the hole was small, everything worked out.
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, you can proceed to the next stage: connection.
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.
