Fitment And Compatibility
Fits Peugeot 407 models (Sedan, SW, Coupé) for the left rear door — the door located behind the driver. Always verify the part number against the damaged unit: common references include 9660699280, 9137K8 and 9137Q7.
How The Part Works
The latch is an electromechanical actuator that interfaces with the vehicle’s central locking system. When the lock command is received (remote or interior switch), the actuator moves the locking striker and operates the mechanical latch. It also allows manual operation from the interior handle or the key cylinder when present.

- Remove The Interior Door Trim Carefully To Access The Locking Mechanism. Keep Fasteners Organized.
- Peel Back The Moisture Barrier And Locate The Lock Actuator Assembly.
- Disconnect The Electrical Connector And Any Linkage Rods Or Cables Attached To The Latch.
- Remove Mounting Screws/Bolts Securing The Latch, Extract Old Unit And Install The Replacement.
- Reconnect Linkages And Electrical Connector, Test Lock/Unlock Function Before Reassembling The Door Trim.
- Reinstall Moisture Barrier And Door Trim, Reconnect Battery And Perform Final Function Check.
Installation Recommendations
- Use Proper Trim Tools To Avoid Damage To Panels And Clips.
- Inspect The Linkage Rods, Clips And Door Striker For Wear Or Misalignment; Replace If Needed.
- Apply Light Lubrication To Mechanical Pivot Points; Avoid Getting Lubricant On Electrical Connectors.
- Test Electrical Connector For Corrosion Or Poor Contact; Clean Contacts If Necessary Before Reinstallation.
- After Installation, Cycle Locking Several Times To Ensure Smooth Operation Before Final Assembly.
Common Failure Causes
Lock actuators and latches typically fail due to water ingress, corrosion of electrical contacts, mechanical wear of gears or plastic components, and broken linkage clips. Symptoms include intermittent or complete loss of locking/unlocking on the affected door, unusual noises during operation, or the door not latching properly.
