Common search terms include part numbers 9660698280, 9135AY and 9135FN — customers and workshops often find the part by these codes.
Technical Information
Manufacturer: Stellantis / Peugeot
Model: Peugeot 407 — Left Front (Driver) Door
Product Codes: 9660698280, 9135AY, 9135FN, F 00
Additional Numbers: 9660698280 F 00 9135AY 9135FN
Function And Application
The unit integrates the mechanical latch and the electric actuator that drives locking/unlocking via the vehicle’s central locking system. It secures the door striker, enables remote central locking commands, and provides the feedback needed for door-open/closed status on the car’s electronics. Designed for Peugeot 407 passenger-side left front (driver) door; compatible across common body styles of the 407 range (check part numbers for exact fitment).
Typical Causes Of Failure
Door locks fail most often due to mechanical wear and environmental damage: worn plastic gears inside the actuator, seized or corroded latch mechanisms, water ingress causing electrical connector corrosion, or damage to linkage rods from repeated strain. Electrical problems in the central locking circuit or a blown fuse can mimic a faulty lock, so confirm electrical supply before replacing the unit.
Installation Recommendations
– Disconnect the negative battery terminal before starting work to avoid short circuits or unwanted airbag/central-locking commands.
– Remove inner door trim carefully to access the lock assembly (expect clips and a moisture barrier).
– Disconnect electrical connector and unclip any linkage rods (note their routing and orientation).
– Unbolt the lock actuator from the door shell and replace with the new unit. Reattach linkage and electrical connector, then test locking/unlocking function before refitting trim.
– Use correct tools (Torx/screwdrivers) and avoid bending linkages. Apply light grease to moving parts and check the striker alignment if the door does not latch smoothly.
– Typical workshop replacement time: approximately 30–60 minutes depending on door trim complexity and experience.
Why Replace This Part
Replacing a worn or damaged door lock restores reliable locking, prevents door ajar warnings, and secures the vehicle. Because this part is frequently identified by its product number, referencing 9660698280 or codes 9135AY / 9135FN speeds up sourcing the correct unit for Peugeot 407 repairs.
