Fitment And Compatibility

Function And Common Failure Modes
The ignition lock barrel controls mechanical engagement of the ignition switch and provides the physical interface for the key. Common failure signs include difficulty turning the key, intermittent loss of ignition power, key getting stuck or broken inside the barrel, and worn tumblers caused by long-term use or debris. Electrical faults in the ignition switch (separate from the barrel) can produce similar symptoms.
Replacement Procedure (Overview)
- Disconnect the negative battery terminal before work.
- Remove steering column covers to access the barrel.
- Disconnect electrical connectors and remove retaining screws or clips.
- Remove the old barrel, install the new unit with the supplied key, and reassemble in reverse order.
- Check steering lock operation and test all ignition positions.
- Immobiliser or transponder key synchronization may be required on some vehicles; a diagnostic tool or dealer assistance could be necessary.
Maintenance And Longevity
Longevity depends on usage and environment. Regularly inspect keys for wear and avoid forcing a stiff key to reduce premature wear. Keep the barrel clean and avoid excess lubrication that can attract dirt.
