Vehicle Compatibility

Cadillac

• SRX — 2004–2006

Important: Vehicle compatibility may vary by production date and immobilizer configuration. Verify that the vehicle uses the B115-PT / B106 Z key profile and Megamos ID48 PK3+ transponder system before cutting or programming.

Programming & Compatibility

This transponder key requires mechanical cutting and vehicle-specific immobilizer programming before use.

The B106 mechanical profile was used on additional GM applications, but a matching B106 / Z blade alone does not confirm electronic compatibility. This key must specifically match a vehicle using the appropriate Megamos ID48 / PK3+ immobilizer system.
