  • Key system
    Patent number: 6940390
    Abstract: A key system using an ID card which can output ID data is combined with a mechanical ignition key. The key system is provided with a transceiver for receiving data from the ID card, a flash memory for storing the ID data and a CPU. When the stored ID data in the flash memory coincides with the ID card data obtained by the transceiver an operation is performed with the ignition key, the CPU enables the operation of an engine start. Furthermore, if the present protection time has elapsed since the CPU recognizes the coincidence of the stored and ID card data, the operation by the ignition key is nullified.
