For example, when the parking position detection switch 58 detects that the ignition switch 82 is on or ACC and the shift lever 16 is located at a position other than the parking position (for example, the D position), the drive circuit 28 causes the key lock. The solenoid 86 is turned on to lock the ignition key 88 with the lock pin 90 so that the ignition key 88 does not come off.

At this time, when turning on the key lock solenoid 86, the timer circuit 30 supplies the maximum voltage to the key lock solenoid 86 for a predetermined time T1 (for example, 1 second) as shown in FIG. The shaft is moved, and for a predetermined time T2 (for example, 60 minutes) thereafter, a hold voltage of about 1/2 of the maximum voltage is supplied to the key lock solenoid 86. The predetermined time T2 is set to prevent the battery from running down.

When the ignition switch 82 is turned off or the parking position detection switch 58 detects that the shift lever 16 is in the parking position, the drive circuit 28 causes the key lock solenoid 8 to move.
6 is turned off to unlock the ignition key 88.
