More Information
Summary:The security system comprises a coil (34) close to the vehicle ignition lock (38), a control unit (10) for energizing the coil and a transponder which comprises a coil (32), a transistor (30) and a transmitter (24) and a power supply (26). In use the coil (32) picks up a conventional alternating magnetic signal emitted by the coil (34), and provides sufficient power to activate the transistor (30) which connects the power supply (26) to the transmitter (24) causing it to transmit an enabling signal to the control unit. The control unit may be programmed to re-mobilize the vehicle engine on receiving of the correct signal.
