Abstract

A security access system and method is disclosed. In one embodiment, a vehicle access security system, comprising a transmitter element, a detector element, a receiver element, and a computational element is taught, wherein the transmitter element transmits a modulated vehicle access signal into a predetermined communications channel, which is detected by the detector element. The detector element is adapted to detect the modulated vehicle access signal and further adapted to have a detector output signal. The receiver element receives the detector output signal and performs at least one signal processing function, wherein the receiver element has a receiver output signal. The computational element accepts the receiver output signal and compares it to a predetermined access code to determine whether a user shall be granted access to the vehicle.
