What Causes a Car Door to Not Close When Locked?
1 Answers
Here are the specific reasons why a car door may not lock properly: 1. Remote lock failure: It is highly likely that the remote lock is malfunctioning or factors such as aging of the car's remote transmitter antenna are causing the remote key to not work. In this case, the spare mechanical key can be used to lock the door. 2. Signal interference: Strong magnetic field signal interference around the car can prevent the smart key from functioning properly, as it uses low-intensity radio waves. 3. Central locking system failure: If a specific door cannot be locked by the central locking system, it may be due to a malfunction in the door lock actuator or door lock controller. Common faults in car central locking systems generally include aging motors, blown fuses in the switch circuit, or failure of the central locking system main unit.
