Abstract
In at least one embodiment, a vehicle apparatus for changing status for a key is provided. The vehicle apparatus comprises a controller. The controller is configured to receive a key identification signal from a first key and to transmit a key status signal indicative of whether the first key is one of a master key and a non-master key based on the key identification signal. The controller is further configured to receive a change request signal corresponding to a request to change status for an additional key from a primary key to a secondary key if the first key is master key.
