To provide a key system which is easy in control and high in safety. In the present key system, an ID card which can output ID data to the outside is combined with an ignition key. The key system is provided with a transceiver for receiving ID data from the ID card, a flash memory for storing the ID data, a CPU, and the like. When the ID data in the flash memory coincides with the ID data obtained by the transceiver and operation is performed with the ignition key, the CPU makes effective the operation of engine start or the like. Furthermore, if the preset protection time has elapsed since the CPU recognizes the coincidence of the two ID data (S1220:NO), the operation by the ignition key is nullified (S1245). |
