What is the Door Lock Relay all about?

Power door locks used to be a luxury feature on vehicles, but they've become so mainstream that nearly every vehicle is now equipped with them. The lock’s function is to make securing your vehicle, as well as passengers, simple and easy. Instead of reaching across the vehicle to lock or unlock the doors, it can be done by simply pressing a button. Pressing the button completes a circuit, enabling the lock actuator to receive power which activates the locking mechanism to the desired position. The circuit is routed through a door lock relay, which acts as a switch to direct the power to actuators on the door locks. When unlock is pressed, the door lock relay switches from a neutral position to activating a pulse of power to the unlock circuits on the actuators. When the lock button is pressed, a pulse of power is switched to the lock circuit of the actuator to lock the doors. When the relay for the door locks is not working properly or sticking, either the lock function, the unlock function, or both are inoperative.

Keep in mind:

  • When service is performed on any electrical system, the battery should be disconnected to prevent accidental damage or injury.
  • If the door lock relay needs to be replaced, it can be indicative of an underlying concern with the power door locks.
  • Some vehicles equipped with remote keyless entry will find the key fob operates the driver’s door lock even while the door lock relay is defective.

How it's done:

  • Test the operation of electric door locks.
  • Test the fuse for that circuit.
  • Test the relay.
  • Replace the faulty relay.
  • Test for proper operation of electric door locks.

Our recommendation:

If you are experiencing problems with your power door locks, have one of our expert technicians diagnose and repair the system. Relays and electrical systems can be complex, and a broken wire or door lock actuator problem can easily mimic the symptoms of a door lock relay and vice versa.

What common symptoms indicate you may need to replace the Door Lock Relay?

  • Power door locks don’t lock when you press the button, while the unlock feature works.
  • Neither the lock nor unlock functions work.

How important is this service?

Power door locks are a convenience feature on your vehicle. If the power locks aren’t working, you can use the key to unlock your door and the locks can be manually operated as well. Have the power door lock system repaired at your convenience.

Mercedes-Benz GLK350 V6-3.5L - Car is not starting - Rancho Santa Margarita, California
Chris was able to come earlier than the appointment time I had originally arranged. Although he was very thorough unfortunately he wasn’t able to diagnose the problem, He gave me some good suggestions going forward of what he thought it could possibly be. He is very knowledgeable And would definitely use him again in the future for any other issues that may arise.
