Description
Overview
This lock set is intended for Peugeot 307 models and contains the driver door lock cylinder, the fuel filler flap lock and the ignition barrel, supplied with three keys. The set is commonly sought by mechanics and DIY enthusiasts under PSA product numbers; using the product code speeds up identification and ordering.
What The Set Does
- Provides mechanical locking for the driver door and fuel filler flap and replaces the vehicle ignition barrel for starting and steering lock function.
- Supplied keys operate all included locks for immediate use after cutting or programming as required.
- Restores secure access and ignition operation when original locks are worn, damaged or compromised.
Compatibility
Designed for Peugeot 307 applications within the PSA family (Peugeot/Citroën). Always verify fitment using the product codes listed below or by matching the existing lock housings and key profile on the vehicle.
Installation Notes
- Driver Door Cylinder: Remove the interior door trim to access the retaining clip and linkage. Release the clip, withdraw the old cylinder and insert the replacement, reconnect linkages and test operation.
- Fuel Filler Lock: Access usually via the trunk or inner wheel arch panel. Remove retaining screws or clips, extract the old lock and refit the new unit, ensuring correct alignment of the flapper mechanism.
- Ignition Barrel: Disconnect the battery before starting. Remove steering column trims, release the retaining fastener or catch, slide out the old barrel and install the new barrel. Reassemble trims and reconnect the battery.
- If keys contain a transponder chip, the chip must be programmed to the vehicle immobilizer using the appropriate diagnostic tool; mechanical keys still need cutting to match the barrel.
Common Faults And Maintenance
Typical reasons for replacement include worn tumblers, corrosion from moisture ingress, broken or bent key blades and ignition barrels that stick or fail to turn. Regular lubrication with a graphite or dry-lock lubricant (not oil-based lubricants) and keeping keys free of debris will help prolong service life.
