This electric right front (passenger) door lock is a direct-fit replacement designed for Peugeot 407 models. It restores reliable central locking and door latching function, making it an ideal choice for professional workshops and experienced DIY technicians. The mechanism integrates the electric actuator and latch assembly to ensure smooth operation with the existing door linkage and central locking system. Commonly referenced by OEM and aftermarket codes, this unit is suitable when the original lock shows symptoms such as intermittent locking, inability to latch, or failure to respond to remote commands.

Key Features

• Other Numbers: 9136FE

Compatibility

Typical fitment: Peugeot 407 passenger (right front) door. Peugeot 407 production primarily covers model years from approximately 2004 to 2011; always check the part numbers listed on the old unit against the Product Codes above to confirm match before installation.

Function And Common Faults

The door lock assembly secures the door in the closed position and works with the central locking system and door handle linkage. Common failure modes include:

• Worn actuator or plastic gears leading to loss of locking/unlocking force.
• Corrosion or water ingress causing electrical contact faults or seized mechanics.
• Broken or fatigued mechanical linkages and mounting points after long service or impact damage.
• Intermittent operation due to connector corrosion or damaged wiring.

Replacement Interval

There is no fixed service interval for door locks; failures typically occur after many years of use or following water exposure, road salt corrosion, or accidental damage. When symptoms appear — such as noisy operation, inconsistent locking, or the door not latching securely — replacement is recommended to restore proper function and safety.

Installation Recommendations

• Preparation: Gather trim removal tools, Torx/Screwdriver set, socket set, and a multimeter for electrical checks.
• Safety: Disconnect the battery before starting work to avoid short circuits and accidental airbag deployment.
• Procedure Overview:
  • Lower the window (if necessary) and remove the inner door panel and any vapor barrier carefully to access the lock assembly.
  • Unplug the electrical connector and detach the mechanical linkage rods from the actuator and latch.
  • Remove mounting fasteners and extract the old lock assembly.
  • Install the new lock, secure fasteners to the manufacturer’s torque where specified, reconnect rods and electrical connector, and reassemble the door trim.
  • Test operation of central locking, manual lock/unlock, and door latching prior to final reassembly.
• Adjustment: Ensure latch alignment and smooth rod connection to prevent binding. Lubricate latch points with an appropriate grease for long-term reliability.
• Recommendation: Inspect door seals and drainage paths for signs of water ingress and address rust or drainage blockages to prevent repeat failures.

Why This Part Fails Most Often

Door locks most commonly fail due to mechanical wear of internal gears, water ingress causing corrosion and electrical faults, or damage from impacts and forced entry attempts. Salt and moisture accelerate deterioration of both mechanical and electrical components, while repeated cycling over many years leads to material fatigue, especially in plastic gear sets and linkages.

Useful Tips For Mechanics And DIYers

• When replacing the lock, compare part numbers on the old unit with the Product Codes listed above to ensure correct fitment.
• Check and clean electrical connectors; a poor connection is often the cause of intermittent faults.
• If uncertain about door alignment or central locking adaptation after replacement, perform a full check of striker alignment and actuator operation before closing the door panel.
