Features
- Direct replacement for the right front (passenger) door lock mechanism.
- Compatible with original door linkages and central locking system.
- Robust mechanical latch and integrated electric actuator for remote locking/unlocking.
- Designed for easy swap with original unit using standard tools.
Fitment
Compatible Models: Citroën C8, Peugeot 807. Check the part number 9136L8 against the unit on the vehicle to confirm fitment. Suited for the right front passenger door application.
How It Works
The unit combines a mechanical latch and an electric actuator. When the central locking signal or the door handle is operated, the actuator moves the latch rods to lock or unlock the door. The mechanism also secures the door in the closed position and provides feedback to the central locking system via the vehicle wiring harness.
Replacement Procedure
- Prepare tools: trim removal tools, Torx/Phillips screwdrivers, ratchet set, pliers. Work on a stable surface.
- Safety first: disconnect the vehicle battery before beginning to avoid short circuits and prevent damage to electronic components.
- Remove the interior door trim panel and any moisture barrier carefully to access the lock assembly.
- Disconnect the electrical connector and unclip/disconnect the locking rods and linkages. Note the linkage orientation for correct reassembly.
- Unbolt the old lock from the door and remove it. Fit the replacement unit in the same position and secure bolts to manufacturer torque where available.
- Reconnect linkages and electrical connector. Reinstall moisture barrier and door trim.
- Reconnect the battery, test locking/unlocking with key fob and door switches, and check mechanical operation of the latch. Adjust linkages if necessary for smooth operation.

- Lubricate moving parts with appropriate light grease after installation to ensure smooth operation and extend service life.
- Verify correct routing and secure fastening of linkage rods to avoid binding or premature wear.
- After installation, perform multiple lock/unlock cycles and check the door closing/locking under load to confirm correct function.
Most Common Reasons For Failure
- Water ingress and corrosion of internal components leading to seized latches or electrical shorts.
- Wear of plastic gears or mechanical parts inside the actuator from repeated use over years.
- Broken or fatigued linkage rods and clips that disconnect or bind the mechanism.
- Impact or door damage (e.g., from accidents) that deforms the latch or misaligns the striker.
- Intermittent electrical faults caused by corroded connectors or damaged wiring.
