Opening the trunk from the alarm key fob (remote trunk opening), from a button in the cabin

Hello, dear friends! Today we are interested in the connection diagram for the trunk opening button.

In practice, installing a button in the cabin that will automatically open the tailgate is not difficult. It's easier than many people think.

The very scheme of opening the trunk with a button is to modify the lock. An electric drive is added to it. He's an activator.

Control button combination

If the power relay is not included in the kit, it can be purchased separately

It is important that the kit contains a special diode. The peculiarity of this part is that the diode passes a current of a certain charge only in one direction

Accordingly, its correct installation is required. The white strip on the part, indicating the positive side, should be turned towards the red wire, and the negative contact - towards the black and yellow negative cable. For correct connection, you must comply with the diagram below.

How to open the trunk using the StarLine A93 alarm key fob

After activating additional channel one, you can remotely open the luggage compartment. On the Starline A93 2Can 2Lin model and the Lada Granta car, this option is carried out as follows:

on the key fob, press the second button for a long time until the corresponding melodic signal (at least 3 seconds);
Then the first key is briefly clicked.

After this, the car blinks its dimensions three times and also gives an impulse to open the trunk. If the security mode is activated, all doors will remain locked, and only the shock sensor will be turned off (for closing the trunk). In this case, the open compartment door will be displayed on the key fob screen.

How to close the trunk using the Starline A93 remote control

The compartment is closed manually due to the fact that modern cars do not have closers. If the car is in security mode, then after five seconds the status will be updated and the compartment lock will be locked. In this case, the bullet will emit a sound signal, and the open door symbol will disappear from the key fob screen. You can open the trunk again either during this time, or after the next command (the second button is long, then the first is short).

Tips for owners of sedans and coupes

You should proceed according to a slightly different scheme if the trunk lid does not open in sedan or coupe cars.

Lower the backrest all the way or even remove the backrest.
Determine the need to remove the inner lining (in some cases you can do without this step).
Try to get into the trunk and use the crank we already know.
If you cannot reach the locking mechanism, you can lengthen the knob using a stick or any other object of suitable design.

Installing the trunk release button - step-by-step instructions

It is better to start the process of connecting the trunk opening button by studying the instructions for the alarm. In the connection diagram, you should look at what color wire from the “signaling” goes to opening the trunk lid. In most cases this is a yellow-red wire.

If so, then the button connection diagram will look like this:

Next, you can begin choosing the location for installing the button and installing all the elements.

Let's look at the procedure for performing work using the example of a VAZ-2107 car:

We install a relay in the engine compartment. This location will be optimal, since you will not need to pull the positive wire very far to the button, and it will be more difficult to find a place under the dashboard. You can attach the relay, for example, to the mount of the windshield washer reservoir

When installing all elements, it is very important to ensure reliable tightness and insulation of contacts; Next, through the standard hole of all the wires, we lay two new wires - to the button and directly to the activator itself;

We carry out wiring to the luggage compartment through the cabin. The easiest way to do this is under the carpet, where the standard wires run; Along the trunk, we also connect the wires going to the activator to the main bundle of wires, and secure the bundle with electrical tape or clamps;

Install the activator on the trunk lid lock

Here it should be taken into account that the electric drive can work both for retraction and pushing. To change the action performed, simply change the polarity of the connection. To connect the activator, you need to remove the lock by unscrewing two nuts and drill a hole in the side of the lock to engage the rod and connect it to the lock tongue. It would not be superfluous to cover the activator and the lock with a casing - this will protect the mechanism from dust, dirt and mechanical damage; Then we look for the most suitable place to install the button. In the VAZ seven, a good option would be to place it on the plastic cover to the left of the driver’s seat - this way the button will always be at hand; Installing the button is very simple: drill a hole in the plate, insert the button, and put on the terminals. The negative wire can be connected right there, to the cover mounting bolt - job done! Testing can be done.

Useful tips

Before starting to work with electricians, you should determine for yourself whether the trunk lid will be opened from the button on the alarm key fob. If yes, then you need to establish what it outputs to the corresponding wire - “plus” or “minus”, since the electric drive can work both for retraction and pushing (depending on the polarity of the connection).

The choice of activator should also be approached responsibly. You should not buy cheap Chinese analogues; it is better to opt for the factory VAZ electric drive.
