Description
Electric central locking actuator for the left rear door of the Peugeot 407. Rear door (driver’s side).
Replacement electric door lock for the left rear (driver’s side rear) door of the Peugeot 407. This direct-fit actuator controls central locking for the rear door and is commonly searched by its product numbers, making it quick to find for both professional mechanics and DIY enthusiasts. The unit restores reliable locking/unlocking operation, eliminates intermittent failures, and is suitable for vehicles equipped with factory central locking systems.
Technical Information

- Other Numbers: E 00, 9137K8, 9137Q7
Function
The actuator is an electrically driven lock mechanism integrated into the door latch assembly. When the central locking system sends a signal, the actuator converts the electrical input into mechanical movement to lock or unlock the door. It also provides feedback to the central locking system via internal microswitches on some variants.
How To Replace
Intended for experienced DIYers and professional technicians. Typical replacement steps:
- Disconnect the vehicle battery before starting any work to prevent short circuits and accidental triggering of electrical systems.
- Remove the interior door trim using appropriate trim tools to avoid damage to clips and upholstery.
- Peel back the vapor/moisture barrier carefully to access the latch assembly.
- Disconnect the electrical connector and unclip or detach the mechanical linkage rods from the lock mechanism.
- Remove the fixing screws/bolts securing the lock actuator and extract the unit from the latch.
- Fit the replacement actuator in the reverse order: secure bolts, reconnect linkage rods and electrical connector, then test central locking operation before refitting the vapor barrier and door trim.
- Check door alignment and smooth operation; lubricate moving linkages and pivot points with appropriate products if necessary.
Installation Recommendations
- Use plastic trim tools to prevent damage to trim panels and clips.
- Label or photograph rod and clip positions before removal to ensure correct reassembly.
- Test the lock cycle several times (lock/unlock with remote and manual) before final reassembly of the door panel.
- Inspect the door for water ingress or damaged rubber seals that may have contributed to failure and replace seals if needed.
Why This Part Commonly Fails
Common causes of actuator failure include plastic gear wear or breakage inside the actuator, motor burnout from prolonged use or overload, water ingress and corrosion of electrical contacts, and seized or bent linkage rods that overload the actuator. Typical symptoms are a door that does not lock or unlock with the central locking, intermittent operation, grinding or clicking noises from the door, or the need to operate the lock manually.
Notes For Professionals And DIYers
Part numbers are frequently used in searches and diagnostics—use the listed codes to confirm match with the vehicle’s existing part. Suitable for mechanics and competent DIY technicians familiar with door trim removal and vehicle electrical systems.
