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.

Joe was professional, knowledgeable, and courteous. He fixed my truck in less than an hour and it is now running smoothly and quietly. My truck has over 100K miles, so I am ecstatic that I've found an affordable option in Your Mechanic and a great mechanic, Joe! Thanks for an awesome experience!

Buick Rainier V8-5.3L - Car is not starting - Austin, Texas
Brian seems like a nice guy. I had a business meeting so didn't get to spend very much time with him. I rated him 3-stars because I question his assessment of my vehicle. Three days prior, I had a coolant flush and oil change by brake check. I had come in for a brake check of my front brakes and they said they were fine but needed to change my oil and coolant. On Brian's assessment, he said he recommended a coolant flush, oil change, front brake replacement, in addition to other things I knew to be wrong with the vehicle. I'm not saying Brian is trying to run up the bill but just find it odd since these were very recently [within a day or two] done.

Michael was excellent not only did he show me the new parts he also showed me the old parts, I was very thankful for that as it was to send to my brother as he requested. He explained everything to me and he was quite patient with me again thankful for that as well. Like I said and another comment he’s a great guy, and performed the job and just a few hours. Thanks Michael for your professionalism and a job well done.
