Verify Immobilizer Key Type

Before any IMMOBILIZER KEY CODE UTILITY function can be performed, the type of Transponder key must be verified. The following steps show how to verify the Transponder key type.

1. Connect the Diagnostic Tester to DLC3 and press the (ON) key.

2. Insert a Registered Master key (Black Key Head) into the ignition key cylinder and turn to the ON position.

A Registered Master Key is required for KEY REGISTRATION, KEY CODE ERASURE, and AUTO REGISTRATION CLOSURE. A Sub Key (Grey Key Head) will not perform these functions.
