Lada service

In general, after almost 6 years, I finally decided to install an electric lock on the trunk, or rather an activator that will open the lock instead of a button.

Kalina has a standard installation of the activator in the trunk, there is even a place and wires with a terminal

but this system is designed to unlock the lock, and not to open it, instead of turning the key in the lock, although there are no places for rods in the lock, apparently another lock is required, but I don’t care, because I just need to disable the mechanical button and open the lock itself

I figured out the position so that I could screw it on properly and have enough traction, I drilled a couple of holes, screwed it on, the block is connected to the wires normally, I tried it and it seemed to work, I slammed the lid and it didn’t open (I had to open it from the inside)

postponed the improvements until the next evening

the next evening I continued to straighten the rod a little, thereby lengthening it and increasing the stroke of the activator and voila, it opens with a bang, I tested it many times, it works without failures)

There’s just one catch: it’s ok to open the key fob, but if you unlock the doors from the button on the driver’s door, the trunk will also open, because According to the developers, the activator should only unlock the trunk lock instead of the key. and the owner opens the trunk himself...

The simplest thing is not to unlock the doors from the button on the door, but since I decided to be clever, I’ll leave this as the last option)

At first I thought of doing magic with the button on the door, but there are only 2 channels: “open” and “close” to the control unit, and the control unit gives signals to the door locks and to the trunk activator.

I went to the control unit, thought I could do some magic with it, took it apart, and there was a circuit board there that couldn’t be done)

Ideally, I would reflash it so that it doesn’t give a signal to the trunk when the button on the door is pressed, but I don’t know how to flash such things(

Then I found a wire going from the control unit to the activator, so I’m thinking about getting tricky with it...

Lyrical digression: xs like on other cars, but on mine it’s very bad that the wires somewhere start in one color and end in another, minus for the VAZ ones(

I have some idea, maybe someone can help me:

Roughly speaking, here is the standard system:

But here’s a thought: maybe there are some types of reverse relays in nature, where when a signal goes through one circuit, the other circuit breaks?

Removing the lock, drive and latch of the trunk lid

To remove the lock, remove the four pistons by prying them off with a screwdriver.

. and remove the lock drive trim.

. disconnect the rod from the lock drive.

Squeezing the clamps, disconnect the lock wire block from the rear wiring harness block. We use a marker to mark the position of the lock relative to the trunk lid.

Using a socket or a 10mm wrench, unscrew the three nuts securing the lock.

Remove the trunk lock with rod and wires. We install the trunk lock in the reverse order according to the previously marked marks. To remove the lock drive, disconnect the lock rod from the drive (see above).

We use a marker to mark the position of the lock drive relative to the trunk lid.

Using a 8-mm socket, unscrew the two nuts securing the lock drive to the trunk lid.

Remove the lock drive.

Using a screwdriver, remove the retaining ring.

Remove the pressure lever.

. and remove the lock.

Remove the pusher with the washer and spring.

We take out the cylinder lock mechanism. We assemble and install the lock drive in the reverse order according to the previously applied marks. To remove the lock retainer.

How to remove the lock and replace the cylinder

To gain access to the trunk lock of the Kalina sedan, it is necessary to dismantle the internal plastic trim. It is held on by two bolts, which makes it easy to remove. They are located in the places where the handle is installed, in the so-called latching pistons. You can pry them off using an ordinary screwdriver.

The design of the trunk lock of the Kalina hatchback consists of two parts. This is the larva and the mechanism itself responsible for blocking the door. Elements must be disconnected individually. Below you will find information about such deletion.

If you need to replace the larva, everything can be done in a couple of movements. All you need is a deep socket and a flathead screwdriver. Then you should unscrew the bolts and release the desired part of the housing. When the work is done, you need to use a plastic screwdriver to remove the clamp, which is attached to the body of the larva. Next, it is carefully removed, holding the spring. Then the replacement is made, but in the reverse order.

Replacing a trunk lock or disassembling the entire mechanism requires a lot of effort. You need to unscrew the door lock using a screwdriver. There are only two bolts, so the job is quick. You can remove the mechanism using a Phillips screwdriver. When everything is done, just pull the lock and it will come out easily.

To summarize, it is necessary to note what tools are needed for the job. These include:

I also want to do this for myself, maybe one of these days I’ll do it

great post. A question from a teapot, so to speak. I don't know much about electrics. But still not enough to pull out the right one from the pile of wires. The question is exactly this. I have a viburnum with an alarm. Moreover, when the electrician installed it, he said that the trunk would be opened with the alarm key fob and with the standard key fob, and said to buy an additional regular four-pin relay. I installed the activator - but it’s not convenient to open it from the key fob - I want to embed a button into the interior. Maybe someone can tell me where and where to get what.

Here you can do everything elementary. The button is placed in the gap of the positive wire. It takes a long time to draw a picture, I’ll try to explain it with my fingers. Take a two-contact button that works to close. Connect one contact to 12V, the other to the plus of the activator. It is advisable to place a diode in the gap in the power wire that goes from the signaling to the activator. Everything will work.

Well, thank you. Almost understandable. I can most likely figure this out.

Hello! Please tell me if it's not difficult. I installed the activator, now the trunk can be opened with the factory key fob. When the car is started, the key fob won't open it. But it opens if you press the unlock button on all doors. Everything would be fine, but I close the doors with a button in the cabin when I drive or stand in remote places. Then I open it in the city, and naturally, the trunk opens with them, I have to get out and slam it. How to prevent the trunk from opening with this button. And also, I want to make a separate button to open the trunk from inside, where should I connect it?

Hello. Read the article carefully, it describes exactly your problem with the door opener button. You'll have to solder the circuit.

Thank you, I have already done the standard wiring. I set the activator to unlock, not to open. Now you only need to press the button on the trunk. In the blog there is

Here’s a question: I did it approximately according to the same scheme), but even after cutting down the second tooth I can’t open the door, I have to press the button on the doors, and maybe I need to change the stops or what?

I don’t quite understand, the button in the doors opens the tailgate, but not the remote control?

thank you, I figured it out) just not a big electrical glitch))

it turned out great) I also spent a long time doing everything, all I have to do is put the button on, but it doesn’t open with my key and for some reason the doors open along with the trunk, I don’t know why

Thank you! I don't quite understand about the doors. When you press the 3rd trunk release button, do the doors open?

Yes, such garbage, because of this I won’t use the remote control, I’ll have to make a button in the door, that’s enough

Hmmm...interesting garbage...I haven’t come across anything like this yet. It’s a pity that you don’t live in Donetsk, it would be possible to figure out what and how
