High-quality electric lock assembly for the left rear door (rear door on the driver’s side) of the Citroën Xsara Picasso. This replacement electric latch (part number 913778) restores reliable central-locking operation, eliminating common issues such as intermittent locking, stuck latches or inability to secure the door. Designed for professional workshops and competent DIY mechanics who service Stellantis compact MPVs, the unit is a direct-fit replacement that simplifies door repairs and improves vehicle security.
Features
- Direct replacement electric latch for left rear door (driver side rear).
- OE Cross Reference: 913778.
- Complete latch mechanism with integrated actuator and microswitches where applicable.
- Designed to work with central locking systems used in Citroën Xsara Picasso models.
Benefits for Mechanics and DIYers
- Saves time on diagnostics by replacing a common failure item known to cause rear-door locking faults.
- Restores mechanical and electrical locking functions without major door disassembly beyond the interior trim.
- Cost-effective solution compared with replacing multiple door components.
Installation
- Prepare: Work on a parked vehicle with ignition off. For safety, disconnect the negative battery terminal before starting to avoid short circuits and electrical damage.
- Remove Interior Trim: Carefully remove the rear door interior panel and vapor barrier to access the lock assembly. Keep fasteners and clips organized.
- Disconnect Wiring: Unplug the door harness connector(s) from the lock actuator and any associated microswitches.
- Remove Old Lock: Unscrew the mounting bolts/nuts securing the lock to the door structure and detach the mechanical linkages (rods) from the door handle and latch.
- Fit New Lock: Position the new latch, attach the linkages and tighten mounting hardware to the vehicle manufacturer’s torque recommendations where available.
- Reconnect Wiring: Plug in the electrical connector(s) and test the locking/unlocking function before reassembling the door trim.
- Final Check: Confirm smooth operation with central locking remote, interior switches and manual handle. Refit trim and ensure water barrier is sealed.
Technical Information

- Other Numbers: NFP
Installation Recommendations
- Disconnect the negative battery terminal before starting work to prevent shorts and protect vehicle electronics.
- Use trim removal tools to avoid damaging clips and interior panels.
- Mark the position of linkage rods and any shims before removal to preserve correct alignment.
- Check and lubricate door latch pivot points and rods with suitable grease to prevent future binding.
- After installation, verify central locking operation from all control points (remote, driver master switch, manual handle).
Most Common Failure Causes
- Corrosion and Moisture Ingress: Water and salt can corrode mechanical parts and electrical contacts, causing intermittent or permanent failure.
- Wear of Mechanical Components: Plastic hooks, bushings and metal linkages wear or break over time, preventing proper actuation of the latch.
- Actuator Motor Failure: The small electric motor or gearbox inside the latch can fail after years of use or heavy cycling.
- Damaged Wiring or Connectors: Chafed wires, broken connector pins or poor ground connections cause loss of signal to the actuator.
- Misalignment: Door sag or bent linkages can prevent the latch from engaging correctly, creating the impression of an electrical fault.
Signs Of A Fault: Door that won’t lock/unlock with central locking, intermittent operation, abnormal noise from the lock area, or the door not staying closed. Replacing the latch assembly 913778 typically resolves these symptoms when the root cause is within the lock itself.
Suitable For: Citroën Xsara Picasso models requiring part number 913778. Always verify the part number against the vehicle’s existing latch before ordering.
