This electric door lock is a direct-fit replacement for the left front (driver’s) door on Citroën C8 and Peugeot 807 models. It replaces the door latch/actuator assembly responsible for locking, unlocking and securing the door. Supplied as a used unit with a guarantee of functionality, it is ideal for professional workshops and DIY mechanics who need a reliable replacement part quickly — often searched for under the code 9135L4.
How The Part Works
The unit combines the mechanical latch and an electric actuator that receives signals from the central locking system and key fob. When activated, the actuator moves internal linkages to lock or unlock the door. The latch also provides the catch for the door striker and enables manual operation from the inside and outside handles.

Replacement is straightforward for experienced technicians and competent DIYers:
- Disconnect The Battery To Prevent Short Circuits And Unwanted Central Locking Activation.
- Remove The Interior Door Trim Panel Carefully To Access The Lock Mechanism (Retain Clips And Screws).

Installation Recommendations
Use care when removing trim to avoid breaking plastic clips. Mark the position of any adjustable linkages before removal to ensure correct reassembly. After fitting, operate the lock several times with the door open to confirm smooth movement and correct electrical operation. If you encounter stiffness or binding, check the striker adjustment and lubrication points. Always reconnect the battery last and verify central locking operation for all doors.
Most Common Causes Of Failure
Electric door locks on these models typically fail due to worn actuator motors, broken plastic gears, water ingress or corrosion inside the mechanism, and weakened electrical connectors. Symptoms include intermittent locking/unlocking, audible motor noise without movement, or the door failing to latch/secure properly. Regular lubrication of the latch points and protection against moisture can extend service life.
