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.

Keep in mind:

Some modern vehicles have a complete door lock assembly which can’t be separated into individual components. These vehicles will need the entire assembly replaced, rather than just the actuator.

Our recommendation:

The door lock system shouldn’t be checked unless you notice that something is wrong. As soon as you notice your vehicle behave oddly when you lock or unlock the doors, schedule an inspection.

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.

Very polite, articulate, knowledgeable, personable and enthusiastic about his job! Chris does not only showcase a mastery of his incredible skills but his approachable personality is very evident. His ability to go ABCD (Above and Beyond the Call of Duty) without ever losing his cool... is unusual compared to most experts that I know! He treats clients and their vehicles as if they were his own blood relatives or his personal vehicle. For all car repair needs, I will definitely recommend Chris!
