How do you change Ford Transit door lock?

To change a Ford Transit door lock, first, remove the interior door panel by unscrewing any visible screws and carefully prying it off. Disconnect the wiring harness from the door lock mechanism and remove the old lock by unscrewing any retaining bolts. Install the new lock in the same position, reconnect the wiring, and reattach the door panel. Finally, test the new lock to ensure it functions correctly before finishing up.
