Car auto lock failures are typically caused by a dead key fob battery, a blown fuse, or a failing door lock actuator.
Possible reasons why your car door isn't locking include problems with the key fob, such as a dead battery and a stuck button. If the key fob is working, the door lock might not be working due to door lock actuator issues, a blown fuse, or faulty wiring.
