Compatibility

Installation Guide
Typical replacement steps for trained technicians or experienced DIYers:
- Disconnect the negative battery terminal to prevent short circuits and immobilizer issues.
- Remove the lower and upper steering column covers to access the ignition assembly.
- Disconnect any electrical connectors and immobilizer coils attached to the ignition barrel.
- Remove the retaining screw or clip securing the ignition barrel, then withdraw the old barrel from the column.

Common Failure Causes

- Failure of associated electrical contacts or immobilizer coil, preventing engine start despite correct mechanical operation.
