Function And Typical Use
This set replaces three security components: the driver’s door lock mechanism, the fuel filler cap lock and the ignition barrel. Together they secure vehicle access, allow normal ignition operation and prevent unauthorized refuelling. Supplied keys operate the mechanical tumblers; if the original keys contained an immobiliser transponder, the new keys may need cutting and programming to start the engine.
Installation Recommendation
Recommended for experienced DIYers and professional mechanics. Basic installation steps:
- Driver’s Door Lock: Remove the interior door panel, detach electrical connectors and lock rods, unbolt the old lock unit, fit the new lock and reconnect linkages. Check door latch alignment and test locking before reassembly.
- Ignition Barrel: Disconnect the battery, remove steering column covers, release the barrel retaining screw or clip and withdraw the old barrel. Install the new barrel ensuring correct alignment; if keys contain a transponder, have them cut and programmed before final assembly.
- Fuel Filler Cap Lock: Access from the filler housing or through the wheel arch/trunk as appropriate, remove retaining screws and replace the lock cylinder. Verify smooth locking and sealing after installation.
General Tips: Disconnect the battery when working on ignition components, use suitable lock lubricant (avoid heavy oils), take care not to force components, and test all functions (locking, unlocking, ignition) before refitting trim. If transponder programming or key cutting is required, consult a qualified locksmith or authorized service.
Most Common Failure Reasons
- Mechanical Wear: Tumblers and plastic parts wear over years of use, causing keys to stick or fail to turn.
- Corrosion And Dirt: Moisture and road salt can corrode lock internals or jam moving parts, especially on the fuel filler lock and door mechanisms.
- Broken Linkages Or Clips: Door lock rods and retaining clips can break or deform, preventing proper latch operation.
- Key Damage: Worn, bent or cracked keys often cause ignition barrels to fail prematurely.
- Electrical Issues (Where Applicable): If a remote or central locking actuator is integrated, actuator failure or wiring faults can mimic lock failure.
Designed as a direct-fit replacement for vehicles using product codes 4162AG and 4162AH, this lock set offers a practical solution when entry, ignition or fuel-filler locking problems occur. Check fitment against the listed models and product codes before installation.
