Start by pulling out the lock from its position while maintaining the connection of inside handle rods followed by disconnecting electrical connectors. Start by placing the inside handle rods onto the lock before aligning the lock through the opening of the inner bar then restore electrical linkage points. Use the following correct fastener tightening order for lock screws when installing: start with top then bottom and middle followed by tightening the screws to 10 n.m (89 lb in). The installation requires a new outside handle rod-to-lock clip that should be mounted onto the lock lever followed by positioning the outside Door Handle rod into the clip to remove any play before installing the clip cover over the threaded rod. After reinserting the inside handle rods into the handle you should attach the water deflector and trim panel and secure the clip back onto the inside handle rods. Conduct a final examination of the Door Lock system for adequate functioning.

One needs to begin front Door Lock replacement on a monte carlo by fully raising the window followed by front door trim panel removal and water deflector and inner energy absorber removal. The process involves disconnecting the handle rods on the interior side of the handle before removing the retaining screw of the Window Channel and ultimately extracting the channel itself. The procedure requires you to unfasten the inside handle rods from the door and remove the outside handle rod-to-lock clip. The replacement of the lock requires using screws (1, 2, 3) to dismantle it from its position and removing it with attached inside handle rods before disconnecting electrical connectors. The inside handle rods should be attached to the lock before fitting the lock through the inner panel access hole while reuniting electrical connectors. Tighten both the lock screws according to the sequence of top , bottom then middle positions to achieve 10 n.m (89 lb in) torque. Install a new outside handle rod-to-lock clip on the lock lever before fastening the outside door handle rod inside the clip to remove any handle rod movement and then place the clip cover over the threaded rod. The new clip needs attachment to inside handle rods before joining them to the handle followed by Window Channel reinstallation along with its retainer screw which should be tightened at 2 n.m (18 lb in). The last step requires reinstallation of the inner energy absorber collectively with the water deflector and the trim panel followed by inspecting the lock system for proper function.
