Why This Part Commonly Fails
Common causes of failure include mechanical wear of tumblers and plastic components from heavy daily use, dirt and debris ingress, corrosion of electrical contacts, broken or worn keys and occasional damage from forced operation. Moisture and long-term exposure to temperature cycles can accelerate contact degradation and mechanical binding.
Notes For Mechanics And DIYers
This unit is supplied with one key. When replacing an ignition switch, inspect the condition of the steering column covers, key, and associated electrical connectors. If the immobilizer coil or transponder components are present, ensure they are correctly positioned during assembly to maintain reliable recognition of the key.
