Function And Common Faults
Door lock assemblies and ignition barrels provide secure entry and start functions. Common failure modes include worn tumblers or wafers, corrosion, key breakage, or mechanical wear in the lock actuator. Ignition barrels can stiffen or fail over time, preventing smooth key rotation. Replacement is typically required after many years of use, exposure to moisture, or after mechanical damage.
Installation Notes
General fitting guidance: remove the interior door trim and disconnect any electrical connectors to access the lock mechanism, unfasten retaining screws and remove the old lock assembly. For the ignition barrel, remove the steering column covers and follow manufacturer instructions to release the barrel from the switch housing. Always disconnect the vehicle battery before working on the ignition system. If the vehicle uses an immobiliser, plan for key programming or synchronization by a locksmith or dealer.
Compatibility & Fitment
Verify compatibility by matching your existing part numbers to 4162Z8 or 4162Z6. This kit is intended for Peugeot 406 fitment; confirm physical match and connector types before installation.
