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.

BMW 740i V8-4.4L - Noise from engine or exhaust - Shawnee Mission, Kansas
i thought it was an Adjusting pulley. Andrew looked and said that the fan blades were no aligned with the the Fan Housing. We then listened and I told him it could be the impeller in the water pump but the sound wasn't "metallic". He said that the impellers in my water pump were a plastic composite. He was right on both accounts. What a PRO! I recommend this guy to anyone. He was on-time, courteous and RIGHT in the diagnosis. I'll ask for him again.......next time something else breaks.

BMW 740i V8-4.4L - Starter - Beaverton, Oregon
Andrew came out last week and troubleshot my car in the garage and said it was the starter motor. I had suspected it was the starter motor but wasn't quite sure so it was good to get a verification. I have to admit, I was kinda skeptical about this home mechanic thing so I was taking a wait and see attitude until after he came back for the repairs. Both times, Andrew showed up early..which is fine by me. Today, when he came back, he went straight to work installing the new starter motor and changed the oil. Car fired right up so I was happy and I've started it a few more times and it is working well and I don't see any oil leaking. If there was a half star option, I'd deduct 1/2 star. Andrew needs to carry some oil rag buckets or something since he put a bunch of oily rags next to the sidewalk and I went out to clean them up (my dad saw them on his way out and text me and I said, it can't be the mechanic) and had to dig up some dirt since the rags were leaking oil. I'm not sure why he thought placing them on the ground was a good idea but oily rags on the ground is never good especially when it's raining. Overall, I'm happy with the repairs and the experience and will definitely consider using the service again especially since I'm working from home and don't get into my normal shop anymore.
