Abstract
An electronic system is provided for use with motor vehicles, homes, offices, factories, or other applications where it is desired to control access and/or operation. The security system utilizes a coded electronic key, preferably in the form of a card, which is connected to a decoder for identification by composing the key code with a stored code. If the electronic key is properly matched to the decoder, the system is allowed to function without tripping alarms. The system includes monitoring devices, supervising cabling and various access points, such as doors, hoods, etc., which, if breached without the proper card in place, will trip an alarm. The system is deactivated with the proper key and the system includes appropriate delays to allow proper parties to move in and out of the secured vehicle, room, etc.
