5. Maintenance
Proper maintenance ensures the longevity and reliable operation of your ignition key switch assembly.
- Keep Clean: Periodically clean the keyholes and surrounding areas to prevent dirt and debris from accumulating, which can hinder key insertion or turning.
- Lubrication: Apply a small amount of graphite lubricant or a specialized lock lubricant into the keyholes once or twice a year, or if the key starts to feel stiff. Avoid using oil-based lubricants as they can attract dirt.
- Check Connections: Occasionally inspect the wiring connections to the ignition switch to ensure they are secure and free from corrosion.
- Key Care: Avoid using excessive force when turning the key. Do not use bent or damaged keys, as this can damage the lock cylinder.
