Description
Electric lock for the right rear door for Peugeot 407 vehicles. Passenger-side rear door.
Product Description
High-quality electric door lock for the right rear (passenger-side rear) door of the Peugeot 407. This replacement lock restores reliable central locking function, ensures secure door latching and smooth operation of the electric actuator. Ideal for professional workshops and DIY mechanics who search by OE numbers (9681337280, 9138N7, 9138V0). Compatible with standard Peugeot 407 door latch mechanisms and wiring harnesses.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 407 (2004–2011)
- Product Codes: 9681337280, 9138N7, 9138V0
- Additional Numbers: 9138N7 | 9138V0 | 9681337280
Fitment And Function
Designed specifically for the right rear door of the Peugeot 407. The unit integrates the mechanical latch and electric actuator used by the central locking system to lock/unlock the door. It operates via the vehicle wiring harness and responds to remote locking, door switches, and the central lock command.
Replacement Procedure
Basic steps for replacement (recommended for experienced technicians or competent DIYers):
- Park the vehicle on level ground, set the parking brake and remove the key from the ignition.
- Disconnect the negative battery terminal to prevent short circuits.
- Remove the interior door trim carefully (unscrew fasteners, release clips) to access the lock assembly.
- Peel back the moisture barrier to expose the locking mechanism.
- Disconnect the electrical connector and detach the locking rods/linkages from the actuator and latch.
- Unbolt the lock assembly from the door and remove the old unit.
- Install the new lock in reverse order: secure bolts, reconnect rods and electrical connector, reseal moisture barrier.
- Reconnect the battery and test door lock operation (manual latch, central locking, remote locking) before refitting the door trim.
Installation Recommendations
- Always disconnect the battery before starting work to avoid electrical damage or short circuits.
- Inspect and lubricate linkage pins and door latch contacts during installation to ensure smooth operation.
- Check the door alignment and striker position if the latch does not engage smoothly; improper alignment can mimic lock failure.
- Use OEM-equivalent fasteners and ensure the moisture barrier is resealed to prevent water ingress.
Why The Part Most Often Fails
Common causes of failure include water ingress and corrosion, wear of the electric actuator motor or internal gears, broken plastic components in the latch mechanism, and weakened linkage or rod connections. Repeated freeze/thaw cycles, rust, and mechanical wear from frequent use are typical contributors. Electrical issues such as corroded connectors or damaged wiring can also cause intermittent operation.
Practical Tips For Mechanics
- When diagnosing, verify both mechanical movement and electrical supply to isolate actuator faults from wiring or control issues.
- Keep OE numbers (9681337280, 9138N7, 9138V0) handy for fast parts lookup and confirmation of fitment.
- Replacing the entire lock assembly is often quicker and more reliable than attempting to repair fragile internal plastic parts.
