How to Replace a Door Lock

Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.

1. Attempt to unlock and lock the interior doors by using the main door lock switch.
2. Locate the door with the faulty lock.
3. If that door has an individual door lock switch, attempt to unlock and lock the door with that switch. This will help determine if the problem is a door lock or a fault in the main power switch.
4. Remove the interior door trim panel on the door with the faulty lock. To do this, remove the screws behind the handle and in the armrest. Then use the trim tool to remove the clips holding the trim to the door. Start at one corner and work your way around.
5. Using a power probe, apply power to the power side of the door lock wiring harness.
6. Disconnect the electrical connector and door lock levers from the door lock assembly.
7. Remove the door lock mounting bolts. Remove the door lock.
8. Install the new door lock. Reconnect the door lock levers and wiring harness.
9. Test the door lock. Reinstall the interior trim panel.
