This replacement set contains the ignition switch (lock barrel) and the fuel filler cap lock supplied with one key. It is intended as a direct fit for Citroën C5 vehicles from the mid-2000s and is commonly searched by reference numbers 4162FE and 4162HE. Ideal for professional workshops and skilled DIY mechanics who need a reliable lock set to restore vehicle security and convenience.

Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Citroën C5 (2005–2007)
• Product Codes: 4162FE, 4162HE
• Other Numbers: Not Available

The set typically replaces the original ignition barrel and the fuel filler cap lock. Many customers search using the product codes 4162FE or 4162HE, so including these references in your order will help ensure correct selection.

Installation Recommendations

• Safety First: Disconnect the negative battery terminal before starting work to avoid short circuits and unintended airbag or electrical system activation.
• Ignition Barrel Replacement: Remove the steering column trim panels, release any retaining clips or screws securing the lock barrel, withdraw the old barrel and install the new unit. Ensure the new barrel engages the steering lock and that the key turns smoothly through all positions before reassembling trims.
• Fuel Filler Cap Lock Replacement: Access the fuel filler lock from inside the wheel arch or by removing the inner trim of the fuel filler area. Remove mounting screws and disconnect any electrical connector for central locking before fitting the new lock.
• Final Checks: Test mechanical operation of the key in ignition and filler cap, verify central locking function if applicable, and re-tighten all fasteners. Do not force the key; if stiffness is present, inspect alignment and tumblers.
• Immobilizer Note: If the vehicle uses a chipped key/immobilizer, key programming may be necessary to enable engine start. Have a dealer or qualified locksmith perform programming when required.

Why This Part Fails Most Often

• Mechanical Wear: Frequent key use causes tumblers and cylinders to wear, leading to key slip or inability to turn the barrel.
• Corrosion and Dirt: Moisture ingress and contaminant build-up in the filler cap lock or ignition barrel can seize components.
• Broken Or Worn Keys: A worn or damaged key can deform internal tumblers and accelerate failure of the lock barrel.
• Electrical Faults (If Applicable): On combined units with electrical contacts, poor connections or worn switch contacts can cause intermittent ignition or accessory faults.
• Age And Usage: Typical service life depends on usage, but locks commonly last many years; heavy use, harsh environments or previous forced entries shorten lifespan.

Replacement of this set restores secure locking and reliable ignition operation. For professional results follow the installation recommendations and, when immobilizer programming is needed, use a qualified technician.

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.

• Model: Citroën C5 (2005–2007)
• Product Codes: 4162FE
• Additional Numbers: 4162FE (used as main reference)

Function And Symptoms Of Failure

The ignition switch assembly provides the mechanical lock for the key and the electrical switching needed to supply power to the starter motor and vehicle electronics. Common symptoms indicating a faulty unit include difficulty turning the key, intermittent loss of electrical functions on accessory and ignition positions, engine cranking problems, or a key that becomes stuck. Electrical wear or internal tumbler damage can also cause no-start conditions or erratic behavior.

Why This Part Fails

Failures are typically caused by mechanical wear of the lock cylinder (worn wafers or tumblers), prolonged use with a damaged or worn key, contamination from dust or moisture, and electrical contact degradation inside the switch. Corrosion and foreign particles inside the column accelerate wear. Steering lock mechanisms associated with the ignition assembly can also seize and prevent normal operation.

Installation Recommendations

• Disconnect the negative battery terminal before starting work to avoid short circuits and deactivate airbags/electrical systems.
• Remove steering column trim carefully to access the ignition switch; retain all screws and clips in order.
• Unscrew the ignition switch retaining screw(s), unplug the electrical connector(s) and remove the old unit.
• Install the new assembly in the same orientation, reconnect connectors and secure fasteners to manufacturer torque where specified.
• Reassemble the steering column covers and reconnect the battery. Verify key operation in all positions and confirm starter and accessory circuits function correctly.
• Note: Some vehicles may require key re-synchronization or immobilizer registration after replacement. Perform security procedures according to the vehicle’s service manual.
• Typical replacement time for an experienced technician: 30–60 minutes.

Tips For Buyers

Search and order using the part number 4162FE to ensure the fastest match. If the original key shows heavy wear, consider replacing or cutting a new key to the correct profile before installation to prevent premature wear of the new lock cylinder.
