1. A method for programming keys to a vehicle to establish primary keys and secondary keys to control vehicle functionality, the method comprising:

  • receiving a key identification signal from a present key;

    generating a key status signal indicative of the present key being one of a primary key and a secondary key in response to the key identification signal;

    transmitting the key status signal to a vehicle interface display;

    enabling a user to change status of the present key from a primary key to a secondary key with the vehicle interface display after determining that the key status signal corresponds to the primary key;

    determining if the present key is an only remaining key from a plurality of programmed keys that corresponds to the primary key; and

    preventing the user from changing status of the present key from the primary key to the secondary key if the present key is the only remaining key that corresponds to the primary key.
