Function And Common Applications
Door locks and the ignition barrel are essential for vehicle security and operation. The driver’s door lock operates the mechanical latch and, in vehicles with central locking, interfaces with the locking actuator. The fuel filler cap lock secures the fuel filler flap. The ignition barrel provides the mechanical interface for the key and may contain or work in conjunction with a transponder key for immobilizer systems. These parts are commonly replaced during repair after wear, damage, or vandalism.
Installation Recommendations
- Preparation: Gather basic trim tools, Torx and metric sockets, and a multimeter. Work in a dry, well-lit area.
- Safety: Disconnect the battery before starting work to avoid short circuits and to protect vehicle electronics. Follow manufacturer procedures for safe disassembly.
- Door Lock Replacement: Remove interior door trim to access the lock mechanism and actuator. Detach linkage rods and electrical connectors, remove mounting fasteners, replace the lock and reassemble in reverse order. Check latch operation and central locking functions after installation.
- Fuel Filler Cap Lock Replacement: Release the filler door trim or access panel (varies by vehicle), unbolt the lock assembly, replace and test for smooth operation and correct alignment.
- Ignition Barrel Replacement: Remove steering column covers to access the barrel. Extract the old barrel following the vehicle’s procedure and install the new one. If the supplied key contains a transponder, additional immobilizer synchronization or key coding may be required for the engine to start.
- Programming Note: If key-to-immobilizer matching or central locking synchronization is necessary, have the procedure performed by a technician with appropriate PSA diagnostic equipment to ensure correct coding and security settings.
Reasons For Failure
- Mechanical Wear: Tumblers and locking internals wear over time, causing sticking or failure to turn.
- Corrosion And Dirt: Moisture ingress and dirt accelerate wear and can seize lock mechanisms, especially on external locks like the fuel filler.
- Electrical Faults: Central locking actuators or wiring faults can make locks unresponsive even if the mechanical latch is sound.
- Key Damage: Worn or damaged keys can deform tumblers and damage the ignition barrel.
- Impact Or Vandalism: Forced entry attempts or collisions can bend linkages or break lock housings.
This lock set is tailored to motorists and professionals who frequently search by part number. Use the listed product codes (4162Y4, 4162Y2) when comparing fits or ordering replacement components to speed up sourcing and ensure compatibility with Citroën C8 / Peugeot 807 body lock locations and ignition assemblies.
