GM 20922231 Front Side Door Lock Assembly

Pry up the door latch handle screw cover at the front edge and remove the screw underneath. Lift off the latch handle assembly and disconnect it, with installation being the reverse of removal. Remove the door handle set bolt by working through the access hole, then detach the outside cap on the lock cylinder. Pull the outside handle in a rearward direction to release it from the door, followed by removing the door handle gaskets and the remaining door handle set bolt. Working through the access hole, disengage the actuating rods from the outside door handle and the key lock cylinder, then remove the lock cylinder. Take off the handle from the door, with installation being the reverse of removal. Remove the outside door handle and the lock cylinder retaining clip from the handle, then take out the lock cylinder from the handle, again with installation being the reverse of removal. Disengage the inside handle-to-latch actuating rods from the inside handle, then remove the outside door handle. Finally, remove the three screws securing the latch to the door and take out the latch assembly, disconnecting the electrical connectors from the latch mechanism, with installation being the reverse of removal.

The door latch strikers should be lubricated with a thin coat of grease to reduce wear and ensure free movement.

The hinges and latch assemblies should be lubricated once every 3000 miles or every three months.
