Troubleshooting issues with your car door lock mechanism

With advancements in technology, car locks have become more convenient. Instead of using a key to unlock your car, you can now press a button or simply walk up to the car with a fob or phone in your pocket. However, with this added technology comes increased complexity, making it harder to pinpoint the issue when something goes wrong.

If you’re experiencing difficulty getting in and out of your car due to a power lock malfunction, here are six common reasons why your door locks may not be working.

Common Reasons Why Your Car Door Won’t Lock or Unlock

  1. Key fob battery dead.

    A simple battery replacement in the key fob could solve the issue. Consult your owner’s manual for the type of battery needed.

  2. Blown fuse.

    Check the power door lock fuse before taking your car to a dealer. The fuse box is usually located near the driver’s side footwell behind a plastic panel. Replace the blown fuse with one of the same amperage.

  3. Key fob malfunction.

    If the battery is not the problem, take the fob to your dealer for diagnosis. It may need to be replaced.

  4. Solenoid malfunction.

    The solenoid inside the car doors may need to be replaced if the door is not locking/unlocking properly.

  5. Rod or connector broken.

    It is possible that a rod or connector has broken, requiring the removal of the inner door panel for diagnosis and repair.

  6. Electrical problems.

    If none of the above solutions work, there may be an electrical issue such as a malfunctioning logic board or a broken wire. This will require further inspection by a professional mechanic.

Most cars still have a physical key that can be used as a backup to lock and unlock the car. Keep this in mind until the issue is resolved by a professional mechanic.
