1. A method for communicating between a vehicle and an authorized user of the vehicle, said method comprising:
- providing the authorized user with a communications device;
transmitting a polling signal from the vehicle that is received by the device when the device is within a predetermined vicinity of the vehicle where the polling signal is in the VHF-UHF band, wherein the time between transmitting a polling pulse from the device increases when the device is determined to have recently received the polling signal; and
transmitting a first command signal from the device to the vehicle to cause the vehicle to perform a predetermined vehicle operation when the device receives the polling signal.

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.
