A system and method of activating and using an auxiliary key fob with a vehicle, including the steps of: pairing the auxiliary key fob and the vehicle; receiving an activation request at the vehicle, the activation request indicating to the vehicle to activate the auxiliary key fob for use with the vehicle; activating the auxiliary key fob in a particular access mode for use with the vehicle; receiving a SRWC credentials signal from the auxiliary key fob at a SRWC passive entry passive start (PEPS) module installed in the vehicle; after receiving the SRWC credentials signal, sending information included in or derived from the SRWC credentials signal to the VSM of the vehicle; determining that the auxiliary key fob is authorized at the VSM based at least in part on the information sent to the VSM; and carrying out a vehicle access function in response to the determination.

User activated/deactivated short-range wireless communications (SRWC) auxiliary key fob

Implementations of the present invention contemplate using the communication infrastructure represented by a network of telematics units communicatively coupled to a telematics service provider (TSP) to implement procedures designed to curtail the load placed on electricity suppliers by electric vehicles during periods of critically high demand for electricity. The present invention contemplates monitoring charging related information for multiple electric vehicles through the telematics units in those vehicles. The invention further contemplates a request from an energy utility for a response to a critically high demand for electricity and the execution of a demand response program (DRP). The DRPs involve aggregating information from a fleet of the electrically powered vehicles, processing the aggregated information, and issuing instructions to one or more vehicles in the fleet that cause the one or more vehicles to reduce the load they are placing on electricity suppliers through their charging activities.
