To remove and install various components of a vehicle's door, such as the latch, lock cylinder, outside handle, inside release handle, and latch strikers, certain steps must be followed. For standard doors, the latch rods must be detached from the lock cylinder, inside lock, and outside handle before removing the three Torx-head mounting screws and the latch from the door. Access doors use two latches, one at the top and one at the bottom, and require the removal of the trim around the latch to access it for removal or adjustment. The lock cylinder can be removed by prying off the retaining clip and withdrawing it from the door handle, while the outside handle requires the removal of the hole plug and bolts before detaching the rods for the lock cylinder and handle itself. The inside release handle must have its cable released and mounting fasteners removed, and latch strikers can be adjusted by loosening the bolts and moving the striker slightly before retightening and checking for proper latch operation.
