Description
Lock set for Citroën C5 2005–2007. Includes driver door lock, fuel filler cap lock and ignition barrel, plus two keys.
This complete lock set is intended for Citroën C5 (2005–2007) owners and professional garages requiring a reliable replacement for worn or damaged locking components. The kit replaces the driver door lock, fuel filler cap lock and ignition barrel and comes with two keys. Commonly searched under product codes 4162HE and 4162FE, this set helps restore secure locking and reliable starting function.
Key Benefits
- Complete set covering door lock, fuel filler lock and ignition barrel for one convenient repair.
- Includes two keys to replace lost or heavily worn originals.
- Direct-fit replacement for Citroën C5 models from 2005 to 2007 (often referenced with codes 4162HE / 4162FE).
- Reduces workshop time compared with sourcing individual components separately.
Function
The locks provide mechanical security and, in the case of the ignition barrel, interface with the vehicle’s ignition and, if present, the immobiliser/transponder system. The driver door lock operates the central locking mechanism and secures the vehicle, while the fuel filler cap lock prevents unauthorized access to the fuel tank.
Installation
Replacement is straightforward for a trained technician or experienced DIYer with basic tools. Typical steps:
- Remove the interior door trim to access the door lock mechanism; disconnect electrical connectors for central locking actuators if present.
- Unbolt and extract the old lock mechanism; install the new lock and check mechanical operation of rods and linkages.
- For the ignition barrel, remove steering column covers, release the retaining clip and withdraw the barrel. Fit the new barrel and reassemble carefully.
- Replace the fuel filler cap lock by removing the inner trim or access panel, unfastening the lock and fitting the new unit.
- Test all functions: door locking/unlocking (remote and manual), ignition turn and key removal, and fuel flap locking.
Installation Recommendations
- Work on a stable, locked vehicle and keep track of small fasteners and clips removed from trims.
- Disconnect the battery if you will be unplugging electrical connectors or working near airbag/steering components to avoid accidental short circuits or system faults.
- If the supplied keys contain a transponder chip, immobiliser reprogramming or key pairing may be required for the engine to start—arrange key programming if necessary.
- Use appropriate lubricants for lock cylinders (graphite or specialist lock lubricant) and avoid excessive oil-based sprays that attract dirt.
Why These Parts Fail
- Wear And Tear: Frequent key use causes mechanical wear of tumblers and barrels over years.
- Corrosion And Contamination: Moisture or dirt ingress can seize components, especially in door or fuel filler locks.
- Broken Plastic Components: Internal plastic parts and retaining clips can crack with age or forceful operation.
- Key Damage: Worn or bent keys can accelerate lock wear or fail to operate the mechanism.
- Vandalism Or Forced Entry Attempts That Damage Lock Mechanisms.
