First possible reason: The door is not fully closely before the locking key is pressed. This means the door is not actually locked. The car owner should check that all doors are well closed before locking them.
Second possible reason: Locking may have failed due to interference by other signals. In this case, the owner should drive the car away from the site with the interference source and lock it again.
Third possible reason: The door lock may have malfunctioned, which necessitates replacement of the lock. Such malfunction may be caused by frequent door slamming.
Fourth possible reason: The car key may have a sensing function that unlocks the car automatically when approaching it. This function may be deactivated by the owner if it is not desired.
If the door cannot be locked normally, it is recommended that the owner should repair it in time to avoid loss of any items in the car.
