Function And What To Expect
The driver door lock secures the door and provides the mechanical interface for central locking on vehicles equipped with it. The ignition barrel houses the key cylinder responsible for turning the ignition switch and engaging the starter. The fuel filler cap lock secures the fuel flap to prevent unauthorized access. Replacing the set restores mechanical locking function and ensures a single key operates all included locks when supplied as a matched kit.
How The Part Is Replaced
- Driver Door Lock: Remove the interior door trim and moisture barrier, disconnect electrical connectors (if actuator present) and linkage rods, unbolt the lock assembly and extract it from the door. Transfer any clips or actuators if required and fit the new unit, then reconnect linkages and test operation before reassembling the door panel.
- Ignition Barrel: Remove steering column covers to access the ignition barrel retaining clip. With the steering unlocked and battery isolated if working near electrical systems, release the retaining clip and pull out the old cylinder. Fit the new barrel, confirm smooth key operation and that the steering lock and ignition positions function correctly.
- Fuel Filler Cap Lock: Access typically from inside the wheel arch or luggage area by removing the inner trim. Unfasten the lock retaining screws, disconnect any electrical connector if present and replace the lock. Test opening/closing and locking before reassembly.
Installation Recommendations
- Use appropriate trim tools to avoid damaging panels and seals.
- Lubricate mechanical linkages and the new barrel with recommended dry graphite or silicone-based lubricant for smooth operation—avoid heavy oils that attract dirt.
- Ensure linkages and rods are correctly aligned and clips are fully seated to prevent binding.
- After installation, verify that the key operates door lock, fuel lock and ignition smoothly and that central locking (if present) actuates properly.
- Where electrical connectors or actuators are involved, inspect wiring and connectors for corrosion or damage and secure all plugs.
Why This Part Most Commonly Fails
- Mechanical wear of tumblers and internal components from long-term use or excessive force when turning a worn key.
- Corrosion and water ingress, especially around door and fuel flap locks, leading to seizure or intermittent operation.
- Broken or bent linkage rods and damaged actuator mechanisms from impact or slamming doors.
- Frozen locks in cold climates due to moisture and lack of proper lubrication.
- Key breakage inside the barrel or worn key profiles that no longer engage the tumblers reliably.
Additional Notes
This set is frequently searched by its product codes 4162VH and 4162PT—include these when searching catalogues or ordering. Supplied with one key; if key duplication or coding is required for immobilizer systems, follow manufacturer procedures. Proper installation restores locking security and prevents further damage to linkage and actuator components.
