Description
Electric central locking lock for the right front door of the Citroën Xsara Picasso. Make sure you have the oval connector identical to the photo. Used part, fully functional, tested. Front passenger door.
Description
This replacement electric door lock is designed for the right front (passenger) door of the Citroën Xsara Picasso. It is a used, fully functional unit that operates the central locking mechanism and interfaces with the door latch, interior/exterior handles and the vehicle wiring via an oval connector. Ideal for professional workshops and DIY mechanics searching by part number (9136J3), the unit restores reliable locking/unlocking and mechanical latch operation without the need to replace the whole door latch assembly.
Function and Common Faults
The door lock actuates the central locking system — converting electrical signals from the car’s locking module into mechanical movement that locks or unlocks the door. Typical failure modes include worn actuator motor or gears, water ingress and corrosion, seized mechanical latch components, or broken plastic linkage. Failures usually develop gradually (intermittent locking, noisy operation) or suddenly (door stuck locked/unlocked) after years of use or exposure to moisture and dirt.
How It Is Replaced
Replacement is straightforward for an experienced technician or competent DIYer with basic tools:
- Disconnect the battery before starting to avoid short circuits and electrical damage.
- Remove the door trim panel and any vapor barrier carefully to access the inner door shell.
- Peel back soundproofing and locate the lock assembly attached to the door shell and latch mechanism.
- Disconnect the oval electrical connector and detach the lock rods/linkages from interior and exterior handles.
- Unscrew the lock unit mounting bolts and remove the old lock.
- Install the replacement unit, refit linkage in the correct orientation, reconnect the electrical connector and secure mounting bolts.
- Before reassembling the door trim, test the lock operation with the battery connected (remote and interior switches) to confirm correct function and alignment.
- Reassemble the door trim and test the central locking system again.

Installation Recommendations
Always disconnect the battery before removal/installation. Use dielectric grease on the electrical connector to prevent corrosion and ensure a reliable contact. Lubricate mechanical latch points with a light white lithium or silicone grease to improve movement and longevity. When reconnecting linkages, ensure rods and clips are seated correctly to avoid misalignment that can prevent the door from locking or opening. Test the unit thoroughly (remote, manual, and interior switches) before final reassembly.
Why This Part Fails Most Often
Failures are commonly caused by moisture ingress leading to corrosion of electrical contacts or gearbox components, wear of the small actuator motor and plastic gears, and physical damage to linkage or latch components. Dirt and lack of lubrication accelerate mechanical wear. Regular inspection and lubrication can extend service life.
Notes For Buyers
Make sure the connector shape matches the oval connector shown in the photos before ordering. The part is intended for the right front (passenger) door of Citroën Xsara Picasso vehicles and is commonly searched by the code 9136J3. As this is a used unit, verify connector compatibility and physical fitment during installation.
