| Summary: | A device according to the present invention is proposed for the keyless operation of a motor vehicle (
8
), having a transponder (
14
) that sends a code to at least one transceiver (
12
). A control unit (
10
) compares the code to an expected code, and upon agreement, enables at least one component (
16, 18
) necessary for the operation of the motor vehicle (
8
), and deactivates it in the shutdown state of the motor vehicle (
8
). A timer (T2, T3) is provided, whose output value is compared to a specifiable time duration (t2, t3), the at least one component (
16, 18
) necessary for the operation of the motor vehicle (
8
) being deactivated when the output value of the timer (T2, T3) exceeds the specifiable time duration (t2, t3). |
