Steps
Remove the door panel
Release the handle bezel, unplug the lock wiring, and remove the trim and screws behind the pull. Roll the window fully up, release the panel sides, and lift the panel away from the door.
Remove the interior handle and lock cylinder
Remove the interior handle fasteners and rotate the handle off its latch rod. Peel back the water shield, release the lock rod retainer, and slide the lock cylinder out of the exterior handle.
Remove the exterior handle
Remove the two retaining nuts from inside the door. Release the lower tabs and withdraw the exterior handle from the door skin.
Transfer the rods and install the new handle
Move the linkage rod into the replacement handle's plastic retainer. Align the new handle with the door openings, secure its nuts, and reinstall the lock cylinder and latch rod.
Reinstall the panel and verify operation
Reattach the water shield and interior handle, then reconnect the lock wiring. Align and secure the door panel, reinstall its screws and trim, and verify the key, lock, and both handles operate correctly.
