Door lock actuators are most commonly electric motors that control a mechanical linkage operating the door locks. In some vehicles they used a system of vacuum motors, hoses and actuators to operate the lock mechanisms. No matter which system your vehicle has there will be a small computer that operates the actuators. The computer will receive signals to lock or unlock a door from the key remote fob, the key lock in the car door, a button on the dash or door panel, or in some case from a remote unlocking signal from OnStar or similar services.

How often do power door lock actuators need to be replaced?

The door lock actuators are a mechanical part that operates every time you lock and unlock the vehicle, so they get used frequently. Due to this frequent use, failure of this item is not uncommon. On some vehicles it's common to have one or more replaced while the car is still under warranty, which can be less than five years old. On other vehicles they can go over 100,000 miles. So it just depends on how much you use the car and what car you drive.

How are power door lock actuator issues diagnosed?

When you have an electronically-controlled door lock actuator that isn't working, the mechanic will need to remove the door panel to verify that it is receiving the appropriate electronic signals to operate the lock motor. If the signals are ok, then the part will need to be replaced. If the signals are not ok, then the issue is with the system that controls the actuator. The mechanic will need to perform an electrical circuit diagnosis to determine why the signal is not reaching the actuator.
