Abstract
An automotive security system in which an infrared motion detector in the handle recess of a door of the vehicle detects the incipient engagement of the handle by an authorized user to trigger the vehicle transponder into transmitting an interrogation signal. The latter is picked up by a portable transponder on the person of that individual and which then emits a coded answer signal. The latter is compared in the vehicle transponder with a stored code and upon agreement the door lock is released so that the lock release is complete as the user exerts an initial pull on the door handle.
