Description
Left rear sliding door lock for CITROEN C8 and PEUGEOT 807 cars
Part description
This left rear door lock (sliding door) is intended for Citroën C8 and Peugeot 807. It is a used original part from the Stellantis group (Citroën/Peugeot), suitable as a replacement in case of central locking failure, problems with closing/unlocking or mechanical wear of the locking mechanism.
The advantage of replacing the entire lock is the quick restoration of the door’s function without the lengthy solution of partial defects inside the mechanism.

Installation recommendations
Generally/typically for sliding door locks: the exact procedure may vary depending on the specific design of the door and the equipment of the car, so work according to the construction of the given door.
1) Before assembly (checks)
- Compare the new and original lock: same fitting, mechanism shape and same connector/wiring.
- Check whether the lock is mechanically damaged (cracks, broken handles) and whether the mechanical part is not blocking.
- If there was also a problem with the handle/cable/pulls, check that they work freely – the fault may not only be in the lock.
2) Necessary tools and materials (in general)
- Basic set of screwdrivers and bits (Torx/hex depending on design)
- Plastic crowbar for removing upholstery
- Clip/Upholstery Pliers
- Work light, gloves
3) Step-by-step assembly procedure
- Turn off the ignition and typically disconnect the battery for safe wiring work.
- Secure the sliding door in the open position so that it does not move by itself during work.
- Disassemble the interior door trim (carefully loosen the covers, screws and plastic clips).
- Disconnect the electrical connectors that prevent access to the lock (depending on the car’s equipment).
- Release the wiring so that the lock can be manipulated without pulling on the wires.
- Disconnect the mechanical lock control (rods/cables) – note their routing and position in the holders.
- Loosen the lock fixing screws and remove the original lock from the door.
- Insert the new lock, seat it in the correct position and fasten (without crossing the threads).
- Reattach the tie rods/cables and check that nothing is rubbing and everything is properly snapped into the holders.
- Connect the electrical connector of the lock and return the wiring to the original sockets.
- Perform a functional check (both manual and electrical if possible) before fitting the upholstery.
- Refit the door trim and all covers/clips.
-
4) Post-assembly checks and test verification
- Verify locking and unlocking and the correct response to the controls (key/central unit depending on equipment).
- Try closing/opening the door several times in succession – the lock must click and release reliably.
- Check that the upholstery is not pressing on the wiring or mechanism anywhere.
5) The most common assembly mistakes + how to avoid them
- Reverse side – before installation, check that it is indeed a lock for the left rear door.
- Poorly routed tie rod/cable – leads to heavy running or non-functioning handle; always return to original holders.
- Non-clicked connector – manifests itself in locking failures; the connector must fit as far as it will go.
- Damage to upholstery and fasteners – use a plastic pry bar and be patient.
Reasons why the part is damaged
- Wear of the mechanics of the lock due to frequent use (latch, springs, cams).
- Pollution and ingress of moisture into the door – stiffening of the mechanism, corrosion, worse operation.
- Impacts and violent closing of sliding doors – overloading of the latch and attachment.
- Electrical fault in the part of the lock (contact/connector/cabling in the door) – the lock may not lock/unlock correctly.
- Bad adjustment of the door or the counter of the lock – the lock is stressed off-axis and wears out faster.
