Many automakers are asking keys to transmit not just the transponder code but also the unique VIN number. These additional security measures need special key programming procedures that are usually not accessible to independent mechanics unless they have access to a dealer-only tool such as Autel's IM608 Immobilizer Scan Tool or Launch Tech's X Prog3 immobilizer scanner.
