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 CL500 V8-5.0L - Radiator - Houston, Texas
If you read nothing beyond this first sentence, just know that Robert is magnificent! On my repair day, Robert showed up promptly at the requested appointment time, sending several heads-up texts prior to his visit. Upon arrival, he very kindly and pleasantly introduced himself, then immediately proceeded to review the requested service and closely inspected the vehicle before bringing out his heavy duty tools. Radiator replacement can be tricky, but Robert tackled it with ease and with a highly professional methodology which can only come from longtime mechanical knowledge and experience. Not only was Robert careful to keep the job site clean and orderly, but he also took delicate care in disassembling components in and around the engine. Once the radiator was successfully replaced and the coolant levels and functionality restored to factory specs, Robert went above and beyond by scanning the vehicle computer for any fault codes, etc. He diagnosed a misfire and tested some ignition components, after which he very kindly suggested what needed to be repaired in the near future. Overall, I will gladly admit that I am very satisfied with the repair work received by Robert. I cannot thank him and YourMechanic enough, as the service received was excellent, affordable, precise, professional and highly convenient. I would highly recommend Robert as a mechanic, as his knowledge, insights, technique and professionalism are without equal.

Mercedes-Benz CL500 V8-5.0L - Pre-purchase Car Inspection - Lumberton, New Jersey
G inspected a Benz CL500 for me. He found multiple issues with the vehicle and saved me a 2 hour drive to Philadelphia to inspect the car myself. His inspection was very thorough; I was highly impressed. He took the time to make sure that I don't get stuck with a lemon; with his findings, he saved me from a potential costly nightmare.
