Abstract
A system and method for providing a polling signal transmitted from a vehicle that is received by a key fob held by an authorized user of the vehicle as the user approaches the vehicle, where the polling signal is a pulsed polling signal in the VHF-UHF band. The polling signal tells the key fob to transmit a command signal that causes the vehicle to perform a predetermined vehicle operation. Alternately, the polling signal is transmitted by the key fob where the vehicle sends an authorization message back to the key fob if it receives the polling signal that tells the key fob to transmit the command signal.
