What is the Door Lock Actuator all about? A door lock actuator is the component in electronic door locks that is responsible for locking and unlocking the vehicle’s doors. When a button is pressed to lock or unlock a door, the door lock switch triggers the actuator. A small motor in the actuator then triggers a series of gears. The final gear is connected to a rack and pinion set of gears, which converts the rotational motion of the motor into the vertical motion necessary to lock or unlock the door. What common symptoms indicate you may need to replace the Door Lock Actuator? Doors won’t lock. Doors won’t unlock. Doors will only lock or unlock sporadically. Doors make an unusual noise while locking or unlocking. Car alarm goes off randomly. How important is this service? A door lock actuator is responsible for locking and unlocking your doors. When the door lock switch is triggered, the actuator’s motor powers a set of gears that lock or unlock your door. When the actuator stops working, there is no communication between the door lock switch and the door locks, and you’ll be unable to lock or unlock the door.
