October 3, 2019
A system includes a communication module configured to establish a first secure communications link with a portable device and a second secure communications link with a contactless smartcard. The contactless smartcard includes a unique identification (ID). A memory module configured to store information associated with the portable device and the contactless smartcard. A temporary key module configured to store the ID of the contactless smartcard and vehicle operation limitations associated with the ID of the contactless smartcard in the memory module. An authentication module configured to (i) authenticate the portable device and (ii) authenticate the contactless smartcard. A passive entry/passive start (PEPS) module configured to receive authentication of at least (i) the portable device or (ii) the contactless smartcard from the authentication module, and perform a vehicle operation based on at least (i) the received authentication and (ii) the vehicle operation limitations stored in the memory module.
