Programming & Compatibility

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

Compatibility must be verified by both the HU58 mechanical blade profile and the PCF7935 / ID44 EWS transponder system. A BMW application using a different blade profile or later immobilizer generation is not interchangeable solely because it uses a visually similar transponder key.
