0 turns off the lamp 21. That is, when the predetermined door of the locked vehicle is unlocked by the normal unlock mode operation by the keypads 12 to 16 provided on the door outer handle disposition portion 10 of the vehicle, mainly in FIG.
Steps S116 to S124 of the flowchart shown in FIG.
The 25th step S125 (regular unlocking means) unlocks (unlocks) the door through the route through the 25th step S125 (see time t4 in the time chart shown in FIG. 15).

When all the doors are automatically locked when the first predetermined time (TAL) has elapsed after closing all the doors, each step S12 of the flowchart shown in FIG. 10 is mainly used.
32nd step S13 via 8, S130 and S131
The 32nd step S132 (automatic locking means) automatically locks (locks) all the doors through the route up to 2 (see time point t5 in the time chart shown in FIG. 15).

Further, within a lapse of the second predetermined time (TUL) after the above-mentioned automatic lock, the predetermined outer door of the vehicle once locked is operated by the simple unlock mode operation by pulling and releasing the door outer handle 11. At the time of unlocking, mainly through steps S133 to S138 of the flowchart shown in FIG. 12, the 39th step S1
By the route to 39, the 39th step S139
The (simple unlocking means) unlocks (unlocks) the door (see time t6 in the time chart shown in FIG. 15).

In summary, in the third embodiment, the predetermined unlocking mode described above is repeated in the twelfth step S112 by repeating the pulling operation (ON operation) and the releasing operation (OFF operation) of the door outer handle 11. Since the door is unlocked (unlocked) when the simple mode matches the preset true value pattern stored in advance, the combination of ON and OFF described above is ON in detail. By combining OFF, ON time, and OFF time, a wider variety of storage modes can be set, and there is an effect that security can be further improved.

In addition, since the allowable range (for example, ± 10% range) of the predetermined width with respect to the true value pattern in the simple mode is set (see step S136 in the 36th step in FIG. 12), the actual value in the simple unlock mode is set. Even if an error within the above-mentioned allowable range occurs in the operation mode of 1, the generated error can be effectively allowed, so that the usability is improved. The other effects corresponding to claim 1 are the same as those in the first and second embodiments described above also in the third embodiment, and thus the duplicate description thereof will be omitted.
