Description
Electric lock for the right rear door for PEUGEOT 407
Door behind the front passenger.
This electric right rear door lock (door latch with actuator) is intended for Peugeot 407 vehicles and fits the passenger-side rear door. It is a direct-fit replacement for common OEM references and is frequently searched by technicians under its product numbers. The unit controls the locking and unlatching of the door within the central locking system and restores reliable mechanical latching and electrical actuation.
Ideal for professional auto workshops and experienced DIY mechanics, this lock helps resolve symptoms such as failure to lock/unlock from the key fob, intermittent central locking operation at the right rear door, or a door that will not stay closed properly. Typical installation time for a competent mechanic is around 30–60 minutes per door, depending on trim removal complexity.
Technical Information

Replacement Procedure
- Remove interior door trim and water shield to access the latch area.
- Disconnect the electrical connector to the actuator and detach any retained cables or linkage rods from the latch mechanism.
- Unscrew the mounting bolts that secure the lock/actuator assembly and remove the unit from the door.
- Fit the new lock into the door, reconnect rods and cables to the correct positions, and secure with the original bolts.
- Reconnect the electrical connector and test locking/unlocking operation before reinstalling the water shield and door trim.
Installation Recommendations
- Use proper trim tools to avoid damaging interior panels and clips. Keep fasteners and clips organized for reassembly.
- Inspect and, if necessary, clean the electrical connector contacts; apply a small amount of dielectric grease to protect against moisture and corrosion.
- Test the actuator and central locking function with the door open before refitting trim to confirm correct mechanical alignment and electrical operation.
- Check the condition of the latch rods and plastic retainers; replace any worn or broken clips to prevent misalignment.
- Typical fasteners are accessible after removing trim; you may need Torx or hex sockets and a ratchet set.
Most Common Failure Reasons
Door lock actuators for the rear doors commonly fail due to moisture ingress and corrosion, wear of internal plastic gears, or electrical motor burnout. Repeated use over many years plus exposure to water and salt can cause the mechanism to seize or operate intermittently. Mechanical damage from door slamming or misaligned linkages can also lead to premature failure. Before replacing the lock, verify fuses and wiring integrity to rule out external electrical faults.
Replacement of the lock actuator typically restores reliable central locking and secures correct door latching. Use the listed product codes when searching for an exact-match unit to ensure correct fitment.
