Description
Electric central locking lock for the right front door for Citroën C3 Picasso. Passenger Side.
Description
This electric door lock (central locking actuator) is designed for the right front (passenger side) door of the Citroën C3 Picasso. Supplied under part code 9136FH and listed by Stellantis (Citroën/Peugeot), the unit replaces a worn or failed door lock mechanism and restores reliable central locking function. Ideal for professional workshops and experienced DIYers who service Citroën vehicles.
Key Functions
- Operates central locking for the right front door (passenger side).
- Integrates with the vehicle’s door latch and central locking system to lock/unlock via key fob or central locking switch.
- Includes the electric actuator and mechanical locking mechanism as a single assembly.
Replacement Procedure
Replacement requires basic door trim removal and electrical disconnection. Typical steps:
- Disconnect the negative battery terminal before starting work.
- Remove the door trim panel and any covers, taking care not to damage clips or the moisture barrier.
- Disconnect the electrical connector to the lock actuator and remove retaining bolts/screws.
- Carefully extract the lock assembly from the door and transfer any required linkages or rods to the new unit if applicable.
- Install the replacement lock, secure fasteners, reconnect the electrical connector and reassemble the door trim.
- Reconnect the battery and test locking/unlocking functions (remote and switch) and check mechanical operation of the latch.
Installation Recommendations
- Always disconnect the battery before disconnecting or connecting the lock unit to avoid short circuits and to protect vehicle electronics.
- Carefully inspect and, if necessary, replace or lubricate linkage rods and clips during installation to ensure smooth operation.
- Protect the door moisture barrier and reseal it correctly after reassembly to prevent water ingress that can damage the new actuator.
- Test the lock operation several times after installation and verify central locking synchronization with the rest of the vehicle.
- If wiring or connectors show corrosion or damage, repair them to ensure reliable electrical connection.
Why This Part Fails Most Often
Common causes of failure include mechanical wear of internal gears or linkages, water intrusion and corrosion (especially when the moisture barrier is damaged), and electrical faults in the actuator motor or connector. Repeated strain from misaligned door components or damaged linkage clips can accelerate wear. Regular inspection and proper sealing of the door interior reduce the likelihood of premature failure.

Notes For Professionals And Experienced DIYers
This part is often searched by the product code 9136FH. Ensure correct fitment by confirming mounting points and connector type visually before final installation. After replacement, verify full central locking functionality and door safety catch operation. If the vehicle exhibits electrical anomalies after fitting, re-check wiring and fuses related to the central locking circuit.
