Tips for choosing a quality lock
Many VAZ-2109 owners are confident that locks from any car will be suitable for their cars.
This opinion is not true. For installation on the “nine”, experts advise buying locks from Lada Kalina. Blockers from this model of a domestic manufacturer are easy to install and, with intensive use, can last 2–3 years. In addition, blockers from the VAZ-21099 model are perfect for the “nine”. These locks have such advantages as low price and long service life (about 4–5 years).
Experienced auto mechanics under no circumstances advise experimenting and purchasing locks from foreign cars for the VAZ-2109. By purchasing such blockers, you will not achieve the desired result, but will only waste your time and money.
Installation:
The trunk lid lock of the VAZ 21099 car is not dismountable, so do not try to repair it or do anything with it. If the lock is in a defective condition and is faulty, then it must be replaced with a new one!
- First, put the entire system back together. That is, if you previously removed the button with the cylinder and a small spring, then install them in their places in the reverse order of removal.
- Next, take the new lock in your hands and install it in its place, still tightening it with the same fastening nuts.
- After installation, try closing and opening the trunk lid. If, when closing the lid, the trunk lock suddenly does not fit into the hole in the latch, usually in this case a distinct knock is heard in the area of the lock, and the lid closes very poorly, in this case:
Replacing the lock cylinder
Experienced craftsmen advise carefully changing the cylinder on the trunk lock. The step-by-step process looks like this:
Using pliers, the end switch of the removed lock is removed. To remove the pin, a hole is drilled. The pin is knocked out through it using a screwdriver. The flap moves back and is pulled out. There is a spring under the damper; it can also be pulled out.
Next, the body of the larva is pulled out. By hitting the back of the body with a hammer, the larva is knocked out. A new cylinder is inserted into the freed body, the pin is hammered in and the ring is put in place. Next, the spring and valve are inserted in the reverse order, and the limit switch is hammered back in. Vedashka is sprayed into the key hole.

Removal:
- At the beginning of the operation, remove the trim from the trunk lid, to do this:
First, use a screwdriver to pry up the “10” pistons and then remove them.
And after removal, remove the trim from the trunk lid of the car.
- When the casing is removed, use a wrench or socket wrench to remove the two nuts that secure the lock to the cover.
When unscrewing the nuts, be careful, because immediately behind one of this nuts there are two “negative” terminals, which can be very easily damaged!
- Next, when the nuts are unscrewed, disconnect these two “negative” terminals from the metal stud.
- And then remove the lock from the trunk lid.
Now let's move on to removing and adjusting the latch.
If you do not want to remove it and know that it is well adjusted, then continue reading below, in the “Installation” section!
- To remove the clamp, first unscrew the two bolts that secure the clamp using a wrench.
If the trunk lid does not close well, or when closing the lid there is an impact in the area of the lock, then in this case, adjust the position of the latch by moving it in the desired direction!
- Then use a screwdriver or hand to pry up the fastener and then remove it from the car body.
If the trunk lid again does not close well and has vertical play, then in this case, adjust the position of the lock exclusively in height!
- Finally, remove all adjusting washers.
If necessary, increase or decrease the number of shims. This will make the trunk lid easier to close!
- To install the lock and door trim in place, follow the steps below:
- First, attach the new lock to the place where the old one was installed.
- Then put two “negative” terminals on one of the studs and then tighten both nuts securing the lock.
- And finally, install the casing in its place, securing it with ten pistons.
- To install the latch, do the same but in reverse order, that is:
- Increase or decrease the number of shims.
- After this, install the lock retainer on top of these washers and subsequently adjust and tighten it with two bolts.
Replacing the hood lock on a VAZ-2109 - we solve the problem ourselves
The variety of cars on the roads of our country can capture everyone’s imagination. However, among our car enthusiasts there are those who would never trade their beloved “nine” for anything. Indeed, the VAZ-2109 rightfully deserves to bear the title of cult, because many of us gained experience behind its wheel. However, we should not forget that at first universal love was very difficult for the car. Not least because of trivial problems with the trunk and hood locks. What can we say, many VAZ-2109 owners still repair these car parts, sparing neither effort nor time.

Replacing the tailgate locking device cylinder
Buying a new car trunk lock and cylinder is quite simple at any auto supply store that sells locking devices for car doors. There is no need to immediately remove the key from the hole in the cylinder, since after this it is almost impossible to put the mechanism back together. You can easily remove the trim and gain access to the trunk locking device by removing a few rivets. After this manipulation, you need to unscrew the two nuts without touching the terminals located on their bolts. The next step is to actually replace the old mechanism and the cylinder itself with new parts. The cylinder and lock should be screwed with factory bolts and the area covered with sheathing.
You can forget about the poorly functioning lock of the “nine” for a long time by trying to change it to the automatic electric lock of the “Kalina”. You need to pay attention to the fact that you should use a lock from a Lada with a sedan body type, and not a hatchback - they differ in their design from each other. The next element of the new design, which will need to be installed in place of the old lock, is the counterpart, which can also be taken from the Lada Kalina lock. It can be easily installed on the trunk of a VAZ 2109 car and does not require significant changes.
Installing a Kalina lock means that it will be opened using an electric drive or mechanically using a lever from inside the car. Therefore, it is worth purchasing a special kit for the central locking. Electrical wiring will require the installation of a button, relay and fuse (8 or 16 A). In addition to these structural elements, you will need two more plastic or rubber plugs, as well as a bracket - a small corner with side dimensions of 30 mm and a thickness of 1-2 mm.
The tools that will help replace the device are:
- angle grinder;
- keys for 8 and 10;
- drill.
The cost of a new device will definitely pay off in a year, so there is no need to worry about your investment. In addition, all the materials required for the new mechanism are quite cheap. Replacing a lock is a very important thing that you can do either yourself or trust the repair specialists.
Installing the lock yourself
First, you need to remove the casing. Then you need to drill two holes to secure the activator. The ground wire is clamped with the activator screw and sealed with sealant. The frame, which is included in the activator kit, bends at approximately an angle of 90 degrees. Although it is better to bend it in such a way that it is easier for the cable to pull out the tongue.
The next step is cutting a steel rod, approximately 4 cm long, which is installed in the activator ring. An adapter is put on its second end, to which the cable is attached. The fastener for the cable sheath can be made from the rest of the frame, which will be clamped with the windshield wiper motor bolt.
Then we lay the wiring inside the trunk door and lead it through the rubber shell into the cabin. In the cabin, you need to bend the edge of the headliner and lay the wire down along the rear pillar, then run it under the carpet and sound insulation. The plastic sheath is then peeled off at the end of the cable and soldered to the frame using a copper washer. Everything is lubricated with sealant.
Next, when installing the trunk lock, the cable is attached to the tongue. It presses well, because the cable is single-core and steel. Next, the shell mount is screwed on. You need to adjust its tension. Connecting the lock according to the standard electrical diagram. You can use the standard activation button. Now all that remains is to check how the trunk opens.
The rear of the eighth and ninth series VAZ cars are designed in such a way that when there is a counter flow of air, they contaminate the rear viewing window of the vehicle. These models drive almost all the time with a dirty rear end. And accordingly, with contamination of the rear part of the vehicle, sand, dirt, moisture and salt solutions get into the trunk lock structure, leading to corrosion on the critical mechanisms of the lock, which often leads to its failure.
But the opening of the mechanism can be activated using a button that is located at the driver’s hand in the car interior. Thus, you don’t have to worry about dirt in the closing mechanism, and it will create more trouble for intruders who want to check the contents of the trunk. It is possible to improve the “closing-opening” device of the trunk on most Zhiguli models.
