Car Door Lock Actuator Replacement Service

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.

Mercedes-Benz CLS550 - Cooling/Radiator Fan Motor - Los Angeles, California
In a word, as a mechanic and representative of the Yourmechanic service, Robert is OUTSTANDING. He arrived on time for our appointment and got to work immediately on installing a replacement coolant fan for my Mercedes CLS 550. When I described another problem I’ve been having that I thought might be related, he agreed to add another repair to my quote on the spot. Luckily, I already had the part, and Robert kindly agreed to install it after the first job was complete. Bottom line, my overheating problem has been fixed and I now have heat in the cabin for those cold mornings. Very happy with the labor I was charged for as well. Perfect experience. Yourmechanic should be proud to employ such a knowledgeable and professional mechanic.
