Abstract: A transmitter includes case, a thin non-conductive pad with an electrically conductive coating applied to selective areas of the pad, one or more electrically conductive actuator buttons on the pad to activate the transmitter, a thin insulator containing a plurality of separate areas which can easily be selectively punched out leaving open holes, and a printed circuit board containing the electronic circuits of the transmitter. Because all of the internal components can be manufactured as extremely thin elements, the transmitter can be made extremely small and thin.

Abstract: A vehicle control and/or access control and/or anti-theft system for motor vehicles including data entry apparatus designed to enter a predetermined signal, a decoder for processing the signal, apparatus to recognize which one of a plurality of valid signals was entered, and apparatus to control vehicle electrical functions in response to which valid signal was recognized. In the anti-theft system, operation of the vehicle is disabled by interrupting an essential vehicle circuit, and a method is provided together with the decoder for preventing the operation of the vehicle disabling system so that when the operator enters his specific signal the automobile can then be started and operated. In addition, the system monitors all points of entry into the vehicle, and also monitors various sensors for unusual disturbances. The system sounds a siren alarm and/or flashes the vehicle's interior lights, parking lights, and/or headlights, in the event of unauthorized entry or unusual disturbance.
