Many car manufacturers are requiring keys to transmit not only the transponder code but also the vehicle's unique VIN number. These additional security measures need special key programming procedures that are usually not available to independent mechanics unless they have access a dealer-only tool such as Autel's Immobilizer Scan Tool (IM608) or Launch Tech's X Prog3 immobilizer scanner. It's important that you choose a PIN which is simple to remember, but difficult to guess by others. The majority of experts recommend using a combination of numbers and letters.
