Function and Symptoms
The door lock assembly integrates the mechanical latch and the central locking actuator. When locking/unlocking commands are sent (remote/central locking), the actuator moves the latch to lock or release the door. Common symptoms of a failing unit include: door not locking or unlocking with central locking, intermittent operation, unusual noises from inside the door (grinding or clicking), or inability to latch the door securely.
How To Replace (General Guide)
- Disconnect the negative battery terminal before starting work to avoid short circuits and prevent damage to electrical components.
- Remove the door trim panel and protective moisture barrier to access the lock assembly.
- Disconnect the electrical connector and unhook any control cables or rods attached to the lock mechanism.
- Unscrew the lock assembly fasteners and remove the old unit from the door shell.
- Fit the new lock in the same orientation, secure fasteners, reconnect cables and the electrical connector. Verify mechanical linkages are correctly seated.
- Reconnect the battery and test locking/unlocking operation before refitting the moisture barrier and door trim.
Installation Recommendations
Always follow manufacturer procedures and use appropriate tools. Ensure the door lock striker alignment is correct after installation—misalignment can cause premature wear or poor latching. Lubricate mechanical moving parts with suitable grease and check the condition of the linkage rods and clips; replace any damaged clips during installation. If the electrical connector shows corrosion, clean contacts or replace the connector to ensure reliable operation.
Why This Part Most Often Fails
Typical failure causes include wear of internal plastic gears or levers, ingress of moisture and dirt that causes corrosion or jamming, broken actuator motor, and mechanical fatigue from repeated use. Water ingress from a damaged moisture barrier or clogged drainage can accelerate wear. Preventive care—keeping the door seals and drainage clear—reduces the risk of premature failure.
Notes For Buyers
Searches by OEM number (for example 9686719880 or 9135FA) are common—use these codes to confirm compatibility. This unit is intended for the left front (driver’s) door of the Citroën C4 first series (5‑door). Suitable for professional workshops and experienced DIY mechanics who perform door trim removal and component replacement.
