Installation Tips

Replacing the lock set typically requires removing interior door panels carefully to access door locks. The ignition lock swap involves disconnecting the steering column covers and detaching the steering lock unit. Fuel flap lock replacement requires access to the fuel filler area. Ensure proper alignment and lubrication to maintain smooth lock function.

Common Issues and Maintenance

Locks often fail due to wear, corrosion, or internal mechanism jamming. Non-moving door locks in this set may be loosened by careful manual adjustment or lubrication. Regular use and exposure to weather conditions impact lock longevity. Using quality replacement parts like this ensures durability and maintains vehicle security.

Complete set includes: driver door lock, passenger door lock, fuel filler cap lock, ignition barrel (steering column lock) and one cut and coded key. Part numbers 4162W5 and 4162S0 identify the set and are commonly used when ordering.

Function And Common Failures

The locks secure vehicle access, enable ignition operation and prevent fuel theft. Common failure causes include worn tumblers, broken lock cylinders, corrosion from moisture, damaged keys and internal mechanical wear. Typical symptoms requiring replacement are sticking or non-turning keys, intermittent locking/unlocking, or ignition key not engaging.

Replacement Guidance

For professional results: remove inner door panels to access door lock mechanisms, disconnect linkages and any electrical connectors where present, unbolt and remove the old lock module, then install the new unit and reassemble. Ignition barrel replacement often requires access behind the steering column; follow vehicle-specific procedures to avoid airbag and steering column damage. The supplied key must be cut or coded to match the new locks—key cutting and synchronization should be performed by a qualified technician if unsure.
