Abnormal behavior of door lock Another symptom of potential problems with electric door lock actuators is a door lock that is not behaving properly. If the actuator has any internal or wiring problems, it may cause them to lock and unlock quickly unexpectedly, or cause them to work intermittently.

Unusual noise from inside the door Abnormal sound from inside the door is one of the symptoms of potential problems with electric door lock actuators. The gears or motors used in most electric door locks may spin quietly or make noises when they are running.

Electric door lock does not work If the door lock actuator fails, they will disable the electric door lock function. This will require the driver to use a key to lock or unlock the door, and for vehicles that do not use traditional keys (for example, newer luxury cars), the electric door lock can be completely disabled.
