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 C300 V6-3.0L - Door Lock Actuator Replacement (Driver Side Front) - Phoenix, Arizona
Mark showed up on time. He was able to remove and replace the actuator with minimal issues. I think this was the first time he's worked on this type of repair on my mode car. He did not have all the tools he needed. I needed to supply a drill and go buy a rivet gun in order to keep the job on schedule. While I appreciated the luxury of not having to take my car somewhere, I didn't appreciate having to buy additional tools to get the job completed that day. I will use Mark again. however, next time I will do my due diligence to find out what tools are needed and check to make sure they are available before beginning.
