Frequently searched under part number 9137A0, this unit restores reliable central locking and secure door latching when the original mechanism has failed.
Technical Information
- Manufacturer: Stellantis (Peugeot/Citroën)
- Model: Peugeot 307
- Product Codes: 9137A0
- Additional Numbers: NFP
Compatibility
Suitable for Peugeot 307 left rear door (driver’s side rear). Always confirm the part number 9137A0 matches the unit being replaced to ensure correct fit and function.
Function
The unit combines an electric actuator and mechanical latch to operate the central locking on the left rear door. When the central locking command is received, the actuator moves the internal linkage to lock or unlock the door and secures the door striker. Proper function is essential for vehicle security and passenger safety.
Replacement Procedure
Basic replacement steps for a competent mechanic or experienced DIYer:
- Disconnect the vehicle battery before starting work to avoid short circuits and protect electronic components.
- Remove the interior door trim and any moisture barriers carefully to access the lock unit. Keep trim clips and screws for reinstallation.
- Disconnect the electrical connector and any door lock rods/linkages (note their orientation or mark positions).
- Remove the fixing screws or bolts holding the lock unit and extract the old unit from the door shell.
- Install the new lock unit (9137A0), reconnect linkages and electrical connector, then test operation before reassembling the trim.
- Reinstall door trim and reconnect the battery. Verify central locking, manual lock/unlock, and child-lock functions (if applicable).
Installation Recommendations
- Always disconnect the battery before removal/installation to protect vehicle electronics.
- Handle plastic linkages and clips with care; replace any brittle clips to avoid future faults.
- Use light dielectric grease on moving linkages and contact points to reduce wear and corrosion.
- Inspect door seals and drainage channels for water ingress—moisture is a common cause of failure.
- After fitting, cycle the central locking several times and check for smooth operation and correct alignment with the striker.
Why This Part Fails Most Often
Common failure modes for rear door locking units include wear or breakage of internal plastic gears, motor burnout due to repeated strain or water ingress, corrosion of electrical connectors, and damaged linkages or clips. Water penetration into the door cavity accelerates corrosion and mechanical wear, making good door drainage and seal condition important for longevity.
Notes for Workshops
Part number 9137A0 is commonly used in replacement searches. Fitment is straightforward for trained technicians; ensure all electrical connectors and linkages are correctly positioned and secured before final assembly.
