Incorrect operation of closing/opening doors makes up the bulk of problems with car alarms. Moreover, if on cars with the simplest configurations this is expected, since you have to assemble the central locking from scratch and configure all the drives (often of questionable quality), then on modern cars with a CAN bus the installer is not immune from problems arising in the future. Knowing the typical problems that arise with the central locking, the car owner can fix everything himself.
Incorrect installation of the system
When installing an alarm system, problems with errors may arise as a result of violations of installation rules. Many specialized centers install the system in a matter of hours, limiting themselves to disassembling the dashboard, one of the thresholds and the glove compartment.
After installation, it is discovered that a web of wires has formed under the steering wheel. Wound with regular electrical tape. The main symptoms of improper installation are:
- Interference during arming.
- The presence of an inscription about blocking on the key fob when asking about the status. It should disappear immediately after arming the car, simultaneously with turning off the engine.
Interference at the frequency of the key fob, as a result of improper installation, prevents the door from opening, so you need to press the Valet button, open the car and turn off the system manually.
In this case, it is necessary to check the installation route of the communication module cable. It may not be laid separately, as required by the installation technique, but rather wrapped in a tangle of other alarm wires. A complete disassembly of the dashboard and review of the installation of the entire system will help to detect other problems.
Useful tips
In order for the door to open in the event of a problem with the key fob, an emergency deactivation procedure must be performed. It involves introducing a special code value, but sometimes does without it. It all depends on the alarm model.
Interested in how to open a Starline car alarm without a key fob, the user needs to perform the following steps:
- Open the door mechanically.
- Turn on the ignition circuit and leave it on for 20 seconds.
- Press the jack mode button three times.”
- Turn off the ignition. If these steps are completed correctly, security mode will be disabled.
You can also use this technique:
- Open the car door, start the engine and ignition.
- Enter the first digit of the password using the Jack button.
- Turn off the ignition and turn it on again.
- Do the second step with the remaining numbers.
After eliminating the reasons for the key fob not working, all that remains is to find the best way to eliminate them.
The Starline alarm system is a reliable system that protects the car from theft, but it may cause problems with opening doors using the key fob. They can be caused by a simple decrease in battery charge or incorrect recognition of signals by the system. But in some cases the situation is more serious and there are several ways to solve the problem.
Broken wire problem
In the transition between the body and the door, in the place where the rubber corrugation is located, the wire responsible for opening and closing the door may be broken. In the open state, due to the bending of the wiring, the contact can function normally, and when closed, the wire opens. You can check this problem as follows:
- Leave the door open and latch it by inserting a screwdriver or any other rod into the lock latch at the end. The effect should be the same as when closing the door on a bracket mounted on the rack.
- Press the limit switch in the door opening so that the electronic systems recognize the closing.
- Security the car. All locks must be locked, and the alarm system will notify you of this with a single sound signal.
- Press the key fob to open/disarm.
If the opening has taken place, then you need to pull the handle on the door to open the latch and slam it, repeating the whole process again. If the locks do not open after this, then the problem lies in the breakdown of the wire responsible for unlocking.
Problems with the central locking
The central locking is the most vulnerable component of the Starline alarm system when controlled from a key fob. The problem is most often detected when the car is idle for more than 1 minute in security mode. The solution is simple, but inconvenient - you need to use a standard key fob to open the doors, or quickly press the open/close buttons. At the same time, when the car automatically starts, disarming occurs in normal mode.
The problem is caused by the fact that the default key fob is not designed to work when the car is running. Arming and disarming occurs correctly, but the central locks do not work. Channel No. 4 is responsible for opening the central lock, allowing you to flexibly adjust the operation of the function. To solve the problem, you need to configure 2 pulses, one of which is responsible for waking up the bus, and the other for opening the doors. This helps to set the central locking to unlock with just one press of a button. However, this action does not apply to opening the central trunk lock.
Problem with opening doors after autostart
After using the autostart function, the Starline alarm system can block the automatic opening of doors even if the system is disarmed. In this situation, you have to use the key and open the car manually. The problem may be caused by incorrect connection to the central locking control circuits during installation. To solve, it is necessary to reconnect 2 alarm wires responsible for controlling the lock, provided that there are no problems with the circuits responsible for the operation of the seat belt. If the seat belt cover in the driver's seat is closed, the doors will not open.
It is also necessary to take into account the indicators on the key fob - unlocked/closed lock. This indication indicates arming or disarming, but not unlocking or locking the door.
None of the alarm systems, including Starline, have the ability to control the process of opening and closing the central lock and simultaneously display the operation on the lock screen.
Starline equipment compatibility
To understand which key fobs are suitable for the installed model, compare the presence of built-in functions:
- control module from a phone via Bluetooth;
- GSM interface;
- LCD display;
- hood lock control;
- engine blocking relay;
- immobilizer bypass relay.
There are not very many interchangeable Starline key fobs, but there are several more options that are only partially compatible with each other. For example, after replacement, auto start, separate opening of the trunk and hood, etc. sometimes do not work. It is better to avoid using key fobs that do not fit completely to avoid system malfunctions.
Problems after replacing the battery
After replacing the battery, the doors may not lock, but the key fob will show a signal that the car has been successfully locked. In this case, you need to pay attention to the option of decoupling the key fob. In order to bind it back you need to:
- Turn off the ignition and press the Valet service button 7 times.
- Turn on the ignition. After this, the system will emit 7 signals, which indicates that the Starline key fob recording mode has been activated.
- Simultaneously press buttons 2 and 3 and hold until a signal notifies you of successful recording.
- Repeat the previous step for all recordable key fobs. Wherein. You must maintain an interval of 5 seconds. The success of the operation is confirmed by a signal.
- Turn off the ignition. This will be followed by the parking lights flashing five times, indicating that the binding is complete.
The problem of unlocking the doors after replacing the battery may be due to other reasons. Firstly, the central locking connector to which the alarm unit is connected may be damaged. Secondly, the fuse on the alarm wire may burn out or the connection to the car's wiring may break.
Other reasons
There are other reasons for car alarm malfunctions, which lead to the fact that it does not close the doors or goes off with a delay.
- Software failure due to activation of security mode when the door is open. In this case, when the door is subsequently locked, the doors will open and will be locked after deactivation. To fix the problem, simply reprogram the remote control, making sure to connect the wires correctly.
- Wiring problems or wiring errors leading to parallel operations. As a result, when you press the buttons on the control panel, the central locking opens or closes.
- If the door lock problem occurs after activating the automatic start, simply review the alarm installation diagram or reinstall the software.
- If there are no external signs of damage, but the display is faulty, you may need to isolate the system from radio interference.
Disturbances in the operation of transmitting elements occur when the vehicle is within walking distance of:
- Airport.
- Busy metropolis with many means of transport.
- Secret military facility.
- Big business.
- Automobile stations.
The signal loses quality even near reinforced concrete structures.
If the signal does not reach the remote control, there is a possibility of a software failure that has led to a loss of communication between the controller and the receiver. If possible, the system can be reprogrammed to suit you. To do this, you need to turn off the control panel in emergency mode by disconnecting the wires, and then synchronize the device with the remote control.
To reprogram the remote, you need to follow the step-by-step instructions.
Sometimes the lack of communication between the communicator and the central unit leads to the disappearance of a running application from the internal memory of the device. In this case, it will not be possible to synchronize the remote control with the ECU. Before this, you need to restore the firmware.
Problems with locking the car with the key fob
The Starline alarm system may have problems locking the car. At the same time, the warning system operates normally, but the doors remain open. The reason may be a simple disconnection of the plug under the driver's seat.
Therefore, the alarm system cannot recognize the signal from the limit switch about the door opening, which entails the automatic installation of the car in the security mode within 30 seconds. The fuses on the contacts in the alarm unit may also be damaged, preventing the signal from being sent. Diagnosis and solution to this problem can be achieved in the following ways:
- Without removing the key from the ignition switch, you must open the driver's door and then remove the key. Then slam the door and put it in security mode.
- Disconnect and reconnect the negative terminal from the battery.
- Pull the handbrake, remove the key, open the driver's door, press the central locking button to close all other doors, close the driver's door and press the lock button on the key fob.
If after these manipulations the problem is not solved, then you need to contact the Starline service center for advice and a possible replacement of the system during warranty service.

It looks like the central locking relay is stuck inside. Check with a tester in continuity mode, the central locking contacts on the signaling unit, with the power supply to the unit turned off. Blue should ring with blue/black, and green should ring with green/black. If one does not ring, then this relay is stuck, then it will ring from black/red. And it hangs at +12V, that’s why it’s +12V on one of the wires.
Here you need to replace the relay. But you most likely will not find such a relay. There it is double, i.e. Inside one case, there are, as it were, two relays. If only some other signal system has the same value.

Abnormal opening/closing of doors
In some cases, the alarm is triggered when the door is closed. In this case, the key fob may display information that the door is open. When you close it again and press the corresponding button on the key fob, the car immediately opens and the alarm goes off.
The problem is caused not so much by the system itself, but by the adjustment of the driver's door actuator. It cannot reach the standard traction, and the limit switch does not allow the central locking to open the doors. In this case, there are 2 options:
- Remove the driver's side door trim and adjust the actuator on the rod.
- Replace the two-wire activator with a similar system, but consisting of five wires. After this, you need to give him control of the central locking from the standard key fob. It is worth noting that this method is the most effective.
- After the car has been idle for a long time and the security system has been disarmed, a problem may arise when the doors automatically close immediately. The problem is solved after pressing the open button a second time.
In addition, the wiring insulation may be damaged and the fuse on the green and blue wires in the central locking connector may have burned out. The presence of a short to ground contributes to the spontaneous opening and closing of doors. The problem may also lie in the equipment being in service mode. In this case, the shock sensor will not work. In this case, the key fob will notify you of a malfunction with a signal displaying a wrench. This icon is selected by button 3 and disabled by button 2.
What to do if the alarm stops responding to the key fob?
If the alarm stops responding to the key fob, the only option to disable the anti-theft system is emergency deactivation.
A special password may be required to complete a task. Depending on your system settings, the code may not be used.
On Starline A1 and A4 models, emergency shutdown without a password is carried out as follows:
- The car door opens.
- The ignition is activated. The system must be left turned on for 20 seconds.
- Press the button to enter the alarm service mode three times.
- The ignition is turned off. Security mode must be deactivated.
On the same alarm models, emergency shutdown using a code is performed as follows:
- The car door opens, the ignition is turned on and the engine starts.
- Using the service button, enter the first digit of the password. The number of clicks must correspond to the symbol.
- Then the ignition is turned off and immediately on.
- Using the service button, you enter the second digit of the password. After turning off the ignition, the security mode should turn off.
