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.

How to replace the rear door lock with a fork bolt lock design and safety interlock feature on Buick Regal?

The door locks feature a fork bolt design which has a safety interlock to secure the door when the fork bolt strikes the metal piece while enabling interior locking by pulling the knob. The process of replacing the rear door lock begins with trimming the panel and removing the water deflector. The first step includes detaching both the outside handle rod from the lock then removing the inside handle rods from the handle followed by removing the clip which connects the inside handle rods to the door. Open the door and unscrew the three lock screws (1, 2, 3) holding the lock to the door before removing the piece with attached inside handle rods. Close the power source before removing the inside handle rods from the lock. Install the door lock by placing its rods through the door inner panel access hole then connecting the electrical connectors. Apply loctite(R) blue gm p/n 12345382 or equivalent before fastener installation then secure door lock screws by following the specified tightening pattern (1, 2, 3) which starts with the top screw followed by the bottom and ending with the middle screw and fasten each screw to 10 N.m (89 lb in). Insert a new outside handle rod-to-lock clip onto the door lock lever followed by attaching the outside door handle rod inside the clip to eliminate any free play and fastening the clip cover over the threaded outside door handle rod. After fitting the clip on the inside handle rods you should proceed to connect these rods to the handle. To complete the installation position the water deflector and the trim panel in its correct position.
