主权项

1. A method for authenticating a remote fob with at least one of a plurality of vehicles comprising:
initiating a passive challenge function in a first vehicle selected from the plurality of vehicles; issuing a vehicle identifier from the body control module of the first vehicle to the remote fob in response to the passive challenge function; issuing a functional transmitter identifier from the remote fob to the body control module of the first vehicle in response to the remote fob receiving the vehicle identifier, wherein the functional transmitter identifier is generated using the vehicle identifier and a stored transmitter identifier of the remote fob; comparing the functional transmitter identifier with at least one authenticated identifier stored in the body control module of the first vehicle; and enabling radio frequency communication between the body control module of the first vehicle and the remote fob when the functional transmitter identifier matches the at least one authenticated identifier.
