Causes of Power Door Lock Failure:

Faulty Actuators: The electric motors inside the door lock actuators can wear out over time, leading to failure.
Wiring Issues: Broken o r damaged wiring can interrupt the signals sent from the switch o r key fob to the actuator.
Weak Key Fob Batteries: A weak battery in the key fob can prevent the remote locks from working properly.
Blown Fuses: A blown fuse can cut off power to the door locks, preventing them from functioning.
