Replace a door lock on Peugeot?

To replace a door lock on a Peugeot, first, ensure the vehicle is securely parked and the battery is disconnected for safety. Remove the door panel by unscrewing any visible screws and gently prying it away from the door. Once exposed, detach the old lock by unscrewing it and disconnecting any electrical connectors, then install the new lock by reversing the process. Finally, reattach the door panel and reconnect the battery to test the new lock.
