Not all car owners know how to open the trunk using the Starline a93 key fob, even despite the obvious convenience of this option. Usually installers activate it during alarm installation, but some, alas, don’t bother. Or they forget to report it.
To check if you can open the trunk using the Starline a93 alarm key fob, do the following:
- On the main key fob, press button 2;
- A short beep will sound;
- Quickly click button 1;
- The key fob will beep three times, the car will blink its headlights three times;
- You managed to open the luggage compartment.
The function works even if the car is armed. In this case, the Starline alarm initiates a temporary shutdown of the shock sensor (so that when the luggage compartment is closed due to an impact, the siren does not blare). At the same time, the open door will blink on the key fob display.
Have you checked?
If Starline a93 refused to open the trunk from the key fob, then this function was not connected to you. The service center may charge a fee for its activation, since the process requires the inclusion of an additional relay in the circuit. If you know anything about wiring, you can try it yourself.
A relay is an auxiliary device that generates a short electrical impulse that triggers an automatic mechanism. In our case, unlocking the luggage compartment.
Is it possible to connect the option on all Starline alarm models?
You can definitely open the trunk using the key fob on the Starline A93 alarm system. The implementation is also feasible on any other model, the main thing is that it has additional channels.
Please note that the car trunk must be equipped with an electric lock (not a mechanical one). If necessary, it is installed additionally.
Trunk lock control
In order to open the trunk using the key fob in the Starline A93 signaling system, the additional channel must be previously activated.
In accordance with the instructions for the car alarm, opening is performed using the following combination:
- First you need to press the second key of the communicator. A second after the click, the first button is pressed.
- The vehicle's lights will blink three times and the communicator will beep three times.
- If the security mode is started, the trunk door lock will open. When the protective function is turned off, the shock sensor will stop working. A symbol in the form of an open luggage compartment will appear on the communicator screen. The sensitivity controller disable icon will also appear on the display.
- When the tailgate is locked while the security mode is on, the sensitivity controller will be activated. Also, five seconds after closing, the trunk control zone will work. The communicator will emit a melodic signal.
The CamRip channel showed how to open the trunk door.
It is possible to use other methods of connecting the option:
- using a flexible configuration method, its implementation ensures that the function is activated based on a signal from the communicator or during a specific sequence of events;
- via the additional Starline P3 module;
- when using the "Latch" mode.
How to enable the “Open trunk from key fob” option
Let's finally look at how to connect the option to unlock the trunk from the alarm key fob. A little effort, and as a result, to open the trunk contactlessly, you only need to press the above combination of buttons on the Starline A93 key fob.
Prepare working tools, a blowtorch, solder, electrical tape, and also buy a power relay with a diode and a platform with wires for them. The diode only allows the set charge current in one direction, so it is important (although the system will work without it, but this is more correct from a safety point of view).
- Carefully remove the trim from the driver's door sill and under the steering column;
- Disconnect the terminals from the battery;
- You need to get to the Starline central alarm unit;
- Unwind the electrical tape from the wiring harness and find the thin black and yellow (brown) tape coming from the 18-pin connector on the system unit. This is the negative output of 1 additional channel Starline a93. This is where the command to open the luggage compartment from the key fob is programmed. If you have a different alarm model, find information in the technical manual about which wires are responsible for additional channels. It is important that the signal on this channel is interval (pulse);
- Positive output – red wire from the engine autostart connector (6-pin);
- Make the connection according to the diagram;
- The triangle highlighted in the diagram is a diode; it is connected between the yellow-black and red wires (between + and -), as well as to the relay. The white mark on the diode means the positive side; accordingly, it should be turned towards the red wiring from the autostart, and the negative - towards the yellow-black wiring from the central alarm module.
- Done, you can connect the battery and test. We described above how to open the trunk using the Starline A93 alarm key fob.
If everything works, all that remains is to insulate the harnesses, hide the central block, and return the cladding to its place.
How to open the trunk lock using the Starline A93 alarm key fob
Modern Starline security systems not only provide vehicle protection, but also allow you to manage additional functionality. For example, opening the luggage compartment door upon command from the communicator. In order to open the trunk using the key fob in the Starline A93 alarm, the electronic key for the luggage compartment must be connected via the analogue channel of the alarm.

What should I do if the doors are locked when opening the trunk using the key fob?
You need to make sure that the firmware versions match. If the microprocessor unit software has been updated, the reason may be that the firmware does not match the machine model.
To fix the problem, you need to roll back the firmware one version back and try using the function again.
If the problem lies in the electronic component, then it is better to contact specialists.
To fix the problem, follow these steps:
- The alarm control panel is removed from the memory of the microprocessor unit and re-linked to the module. Sometimes the problem can be solved by reprogramming.
- All electrical circuits of the anti-theft complex are diagnosed. You need to check the wires connected to the microprocessor module. The cause of the problem sometimes lies in their short circuit or breakage. Damage to the insulation layer can also cause a problem. The test is carried out by a qualified electrician using an appropriate tester.
- The operation of the microprocessor unit is diagnosed. The reason for its failure may be moisture getting inside the device. It is necessary to disassemble the module housing and diagnose it for damaged elements and contact tracks. Failed components must be re-soldered, but this must be done carefully, using a soldering iron with a thin tip. If there are traces of moisture, the board should be dried, but it should not be placed on a battery or near a gas stove. Drying the board with a construction or household hair dryer is not allowed.

What should I do if the alarm goes off when the trunk is opened using the key fob?
If the Starline A93 alarm is automatically activated when the trunk door is opened, then the reason may be that the trunk door itself is too heavy.
In addition, the reason may be that the controller is set too high. When a command is issued from the communicator, the locking device is disconnected from the lock, but the trunk door cannot open.
It rises a little, but this is not enough to trigger the limit switch, resulting in the reactivation of the protective function.
Depending on the connection method, the hood and trunk limit switches may be connected to one power line by default.
As a result, they will be independent of each other, but their activation will be performed synchronously. To solve the problem, it is necessary to separate the pulse signals; for this, diode elements must be installed in the electrical circuit break.
If they burn out, then the electrical circuits should be separated in the microprocessor unit.

Frequent problems and solutions
Well, now you know how to open the trunk using the Starline A93 remote control. What problems can happen in the process?
If everything is connected correctly, but you can’t open the trunk using the key fob:
- Check the battery in the remote control and replace if necessary. Also make sure the car battery is charged and working properly;
- Check the trunk servo. Listen for a click when you press a command on the key fob. If there is no sound, no current is supplied to the electric lock. The device needs to be opened, disassembled, cleaned contacts, connectors, and checked the functionality of internal parts (gears).
- The wires supplying the system are damaged, the connection is made incorrectly. Using a multimeter, test the wires for contact. Make sure the diode is positioned correctly;
- Perhaps the central module is to blame. As a rule, in this case the user should have noticed other “bells” (glitches in the alarm system). Remove it, disassemble it and inspect it. If the board is wet, dry its insides. Clean the contact pads and remove dust with a soft brush. Assembly is performed in reverse order;
- The limit switch on the trunk is not positioned correctly (has moved). Its position needs to be adjusted - raised higher or lowered lower.
If you have checked and ruled out everything, but the option still does not work, we recommend contacting a service center. It may be necessary to change the Starline firmware (for normal interaction with the servo drive and relay).
That's all for us. We told you how to open the trunk on the Starline a93 alarm system from the key fob, as well as how to connect this function. Enjoy it for your health!

Sequence of actions for self-installation of an electric lock
- We place the machine within the perimeter of the repair area; you can use a flat platform with unobstructed access around the perimeter. A road overpass or inspection channel in this case is not so effective, since the driver is limited in movement.
- Open the luggage compartment lid, unscrew the two mounting screws, and remove the inner part of the plastic trim.
- We connect the block with two wires (“plus” and “minus”). “Mass” is black. We pack the cables in a corrugated cable, lay it along the inner cavity of the trunk lid, and lead it out into the technical hole.
- We run the wiring in the corrugation under the side decorative inserts and lower it into the lower channel. First remove the plastic covers and sound insulation.
- We go to the fuse block, namely to fuse No. 10A.
- Next, we install a four-pin relay, connect the terminals of the wires from the trunk, fuse and mechanical button. We power the minus from the radio.
- We install a mechanical button instead of a plug under the optics regulator (hydraulic corrector).
- We assemble the casing and check that the system is working properly.
Button combination for trunk control
According to the user manual, the trunk is controlled using the key fob buttons as follows:
- Long press the second key on the communicator. You must wait 1-3 seconds and then briefly press the first button.
- The car lights should blink 3 times. The key fob will emit three short beeps.
- When the security function is turned off, the luggage compartment lock will open. If it is turned on, the shock sensor is also deactivated. An open trunk icon and an icon for disabling the sensitivity controller will appear on the control panel screen.
- When closing the luggage compartment of a car with the security mode turned on, the sensitivity controller is turned on. The trunk closing time is 5-6 seconds. As soon as it closes completely, the key fob will emit a beep.
