This replacement electric central locking actuator is designed for Peugeot 407 and is aimed at professional mechanics and DIY enthusiasts who service passenger doors and central locking systems. The unit restores reliable door locking and unlocking on the left rear (driver’s side) door, eliminating symptoms such as intermittent locking, clicking noises from inside the door, or a door that fails to lock with the remote or central locking command. The part is commonly searched by its OEM numbers, so including the part codes below increases the chance customers find the correct replacement quickly.
Technical Information
- Manufacturer: Stellantis (Peugeot / Citroën)
- Model: Peugeot 407 (Left Rear Door – Driver’s Side)
- Product Codes: 9681337380 M00
- Additional Numbers: 9137K8, 9137Q7
Function And Common Symptoms
The actuator controls the central locking mechanism inside the door, converting electrical signals from the locking system into mechanical movement that locks or unlocks the latch. When the actuator begins to fail, common symptoms include:
- Door does not lock or unlock with the remote or central locking switch.
- Audible motor or grinding noises from inside the door panel when operating locks.
- Intermittent operation—works sometimes, fails at other times.
- Door remains stuck in locked or unlocked position.
Installation Recommendation
Recommended for installation by a trained technician or a competent DIYer with basic tools. Typical replacement steps:
- Disconnect negative battery terminal or isolate the vehicle electrics to avoid short circuits and accidental airbag deployment.
- Remove the inner door trim and any moisture barriers to access the lock assembly.
- Locate and remove retaining screws or clips securing the lock actuator and latch assembly.
- Unplug the electrical connector and detach the mechanical linkages, noting their positions for correct reassembly.
- Install the new actuator, reconnect linkages and electrical connector, then test central locking operation before reattaching the door trim.
- Check for correct latch engagement and lubricate mechanical linkage points with a suitable lubricant if required.
Test the lock function several times after installation and check that door opens and closes smoothly. Replace any damaged fasteners or door seals found during the repair.
Why This Part Fails Most Often
- Water Ingession And Corrosion: Moisture entering the door can corrode electrical contacts and motor windings or cause connectors to fail.
- Mechanical Wear: Plastic gears and small mechanical components in the actuator wear out over time, causing slipping or jamming.
- Electrical Issues: Broken wires, poor connector contacts, or blown fuses in the central locking circuit can make the actuator appear faulty.
- Foreign Objects And Dirt: Debris in the latch mechanism can increase load on the actuator motor, accelerating wear.
- Age And Usage: Repeated cycles over many years eventually degrade motor performance and internal components.
