How to replace the front door lock on Buick Regal?

The front door lock replacement process begins by removing the trim panel together with the water deflector. You must first disconnect the inside handle rods from the handle before removing their attaching clip that fixes them to the door. Side cutters can remove the outside handle rod-to-lock clip from the lock before you discard it and unscrew the remaining clip portion. The installation starts with removing screws (1, 2, 3) which hold the lock to the door followed by disconnecting electricity wires before taking out inside handle rods from within the lock. When installing place the inside hand rods on the door lock then insert the door lock through the inner panel access hole. Apply Locktite(R) Blue GM P/N 12345382 or Canadian P/N 10953489 or equivalent solution onto the electrical connectors before assembling the door lock screws by tightening them to 10 N.m (89 lb in) in the correct sequence starting with top, bottom, middle, 1, 2, 3. Fasten a fresh outside handle rod-to-lock clip at the door lock lever before inserting the external rod to ensure no slack occurs while securing the clip cover on the threaded rod. First mount the clip onto the inside handle rods before you attach the internal rods to the handle unit. The installation process ends with water deflector and trim panel replacement.
