In step S408, if the frequency of the radio signal transmitted by the keyless entry key can be scanned (OK) (Yes), that is, the key frequency when the door is opened is detected by the reception level detecting section 24. If it is possible, the MCPU 5 displays a message "Register key frequency as when the door is opened?" For confirmation on the display unit 9, prompts the user to make a judgment operation, and enters key operation input waiting processing (S409). . If it is determined in step S409 that the user registers the frequency by operating the number button 11 or the like (Yes),
The frequency determination unit 25 confirms the local oscillation frequency generated by the frequency synthesizer unit 4 by the frequency determination unit 51 of the MCPU 5.

U5 uses the clock circuit 19 to start counting UP of the timer (S513), and determines whether the count of the timer is less than or equal to a specific time U seconds (S51).
4). If the count of the timer is less than or equal to the specific time U seconds in step S514 (Yes), the reception level detection unit 2
Whether or not the frequency of the key can be scanned is determined from the output signal of No. 4 (S515). If the frequency of the key can be scanned in step S515 (OK) (Yes), that is, if the key frequency when the door is closed can be detected by the reception level detection unit 24, the frequency determination unit 25 determines the frequency of the MCPU 5. The local oscillation frequency generated by the frequency synthesizer unit 4 is confirmed by the unit 51, and the MCPU 5 determines whether or not the confirmed frequency is different from the key frequency when the door is opened stored in the frequency memory unit 26 in step S410. Perform (S516). When it is determined in step S516 that the two frequencies are different, the MCPU 5 stores the confirmed frequency in the key frequency memory unit 26 as the key frequency when the door is closed (S517). In addition, at this time, the memory unit 2 is also provided with a notification form when the unresponsiveness function is stopped.
No. 6 is stored (S517).

If the user determines not to register the frequency in step S512 (No), or if the count of the timer is larger than the specific time T seconds in step S206 (No), or in step S516. In both cases where it is determined that both frequencies are the same (No), the MCPU 5 stores the same key frequency in the key frequency memory unit 26 when the door is opened and when the door is closed (S51).
8). At this time, the notification mode at the time of starting and stopping the unresponsiveness function is also stored in the memory unit 26 (S518).
After executing the operation of step S517 or step S518, the process returns to the normal mode (S519).

On the other hand, when it is determined in step S409 that the user does not register the frequency by operating the number button 11 or the like (No), the frequency determining section 25 causes the frequency determining section 51 of the MCPU 5 to determine the frequency. Check the local oscillation frequency generated by the synthesizer section 4. M
The CPU 5 stores the confirmed frequency in the key frequency memory unit 26 as the key frequency when the door is closed (S41).
1). In addition, at this time, a notification form at the time of stopping the unresponsiveness function is also stored in the memory unit 26 (S411). After the operation of step S411 is performed, the operation proceeds to step S612 of FIG. The operation of steps S612 to S619 of FIG. 6 is the same as that of steps S512 to S519 of FIG.
Is the same as reading "stop" and "stop" is read as "start". When it is determined in step S404 that the frequencies are the same by the user operating the number buttons 11 or the like (No), the process proceeds to steps S701 to S707 in FIG. Regarding this operation, steps S204 to S21 in FIG.
The operation is the same as 0.

Next, the operation of the key interlocking response disabling function of FIG. 8 will be described. In the operation of the function, in the operation of FIG. 3, the "key frequency" portion of steps S302 and S308 is changed to "key frequency when the door is open" in step S802 and "key frequency when the door is closed" in step S808. It is the same except that it is replaced, and step S801
The operations of to S811 correspond to the operations of steps S301 to S311. If the key frequency when opening and closing the door is the same, the operation of this function is completely the same as the operation of FIG.
