Set Of Locks For CITROËN C8
Driver Door Lock, Fuel Filler Flap Lock And Ignition Barrel
!!!!! Passenger Door Lock Missing !!!!
Plus 1x Key
Overview
This lock set is a practical replacement kit for Citroën C8 owners and professional workshops. The kit includes the Driver Door Lock, Fuel Filler Flap Lock and Ignition Barrel, delivered with one key. The Passenger Door Lock Is Missing in this set, so an additional cylinder will be required if a complete four-door replacement is needed. Product Codes 4162Y4 and 4162Y2 are commonly used when searching for direct-fit parts for C8 and related Peugeot 807 vehicles.
Fitment
- Citroën C8 (Models Sharing The PSA Large MPV Platform)
- Often Compatible With Peugeot 807 (Same Platform)
- Typical Model Years: 2002–2014 (Verify Specific Year/Trim Before Installation)
Function And Common Faults
The set covers three key functions: locking/unlocking the driver door, securing the fuel filler flap and operating the ignition barrel. Typical failure modes include mechanical wear of tumblers/wafers, corrosion and seized cylinders caused by moisture or road salt, broken key blades or worn key profiles, and internal linkage or actuator wear in the door mechanism. Ignition barrels can additionally suffer from worn tumblers causing the key to stick or turn poorly; if the vehicle uses an immobiliser system, a key without the correct transponder will not start the engine.
Installation Recommendations
- Disconnect Battery Before Starting Work To Avoid Short Circuits And To Protect Electrical Systems.
- Driver Door Lock: Remove Door Trim Panel, Disconnect Linkages And Electrical Connectors, Extract Lock Cylinder Retaining Screws Or Clips, Fit New Cylinder And Reconnect Linkages. Adjust Rods And Lock Mechanism For Smooth Operation.
- Ignition Barrel: Remove Steering Column Covers, Withdraw Barrel Retaining Screw Or Clip, Slide Out Old Barrel And Replace With New Unit. Reassemble Covers And Verify Steering Lock Function.
- Fuel Filler Flap Lock: Access Via Wheel Arch Liner Or Trunk Depending On Vehicle Layout, Remove Retaining Fasteners, Replace Lock Cylinder And Seal Against Moisture Ingress.
- Lubrication: Use Dry Graphite Or Silicone-Based Lock Lubricant; Avoid Petroleum Oils That Attract Dirt.
- Keying: The Supplied One Key Will Operate The Included Cylinders If They Are Factory-Matched. If Locks Are From Different Sets, Cylinder Reprofiling Or Rekeying May Be Required.
- Final Check: Verify Locking/Unlocking, Central Lock Function (If Applicable) And Ignition Operation Through Several Cycles Before Reassembling Panels.

Why This Part Fails Most Often
Locks and ignition barrels are subjected to constant mechanical stress and environmental exposure. The most frequent causes of failure are worn internal tumblers from long-term use, corrosion from water and salt exposure, broken or bent keys, and physical damage from attempted theft or accidents. Poor lubrication and ingress of debris accelerate wear and can cause sticking or jamming of the cylinder.

Note On Keys And Immobiliser
