Abstract

A system for providing dynamic access to a vehicle via a plurality of devices. A device and/or a server of an authentication network stored fob data relating to one or more key fobs linked to the vehicle, and device data that includes data relating to one or more devices linked to the key fob that are authorized to access the vehicle. The vehicle receives an access request indicating that a new device is requesting access to the vehicle, whereupon a challenge may be transmitted to one or more of the authorized devices. The one or more devices may respond, granting access to vehicle functions. The vehicle and/or authentication network generate a secure fob key and access limitations based on the response and transmit the secure fob key to the new device. Profile templates may be used to set and control vehicle access and functions.
