Abstract

An automobile anti-theft device connected to the electrical system and fuel line of a vehicle. A control unit is positioned proximate to an operator of an automobile. The control unit has a first display and a key-pad for the generation of a personal access code for transmission to a circuit unit. The circuit unit includes a programmable read-only memory which compares the personal access code to a stored keyed access. The circuit unit generates a second signal upon acceptance of the personal access code by the programmable read-only memory. The second signal is received by a silicon control rectifier which opens a valve attached to the fuel line of an automobile permitting fuel passage to the engine. The control unit includes a locked retractable penetrating adapter which may be retrieved for modification of the stored key access within the programmable read-only memory. A remotely located programming unit has a receiving adapter, a second display, and a second key-pad for coupling to the retractable penetrating adapter during the modification of the stored key access. The remotely located programming unit may then be stored at a secure location by an individual. A fuel-monitoring transponder and transducer are attached to the fuel line and are in communication with the first display for communicating the passage and consumption of fuel by the vehicle.
