What Causes Central Locking System Failure in Cars?

[KingMarie]

Car central locking system failure can be attributed to the following reasons: Controller malfunction: When the central locking system fails, preventing the car doors from locking, it is usually due to faults in the door lock actuator or the door lock controller. Vehicle body or remote key issues: Remote car lock failure could be caused by problems with the vehicle body or the remote key itself. Malfunctions in the remote key's timing control module or aging of the car's remote transmitter antenna may render the remote key ineffective. Incorrect central lock power connection: If more than 10 incorrect code signals are input, the system will assume the central lock power is incorrectly connected and will stop receiving any signals, including correct code signals.
