[DeLeo]

Sagitar car door cannot be locked. If the remote key fails to lock the door, first check whether any door is not properly closed. Poor contact in central control wiring: It is necessary to disassemble and inspect the faulty door to check whether the lock actuator is functioning. If it is not functioning, it is likely due to poor contact in the central control system wiring. If it is functioning, the issue may be due to high resistance in the locking mechanism, which is usually caused by rust; it could also be due to the displacement of the door lock motor latch position, which can be resolved by simple adjustment. Door lock motor damage: Another possible reason is that the door lock motor is damaged and lacks sufficient pulling force, requiring motor replacement. In this case, it is advisable to visit an auto accessory shop and have a technician who installs central control systems perform the repair.
