PURPOSE:To prevent an automobile from being stolen, by making a system so as not to shift to a stand-by state at a time when a trunk and a bonnet have been opened, after keyless locking. CONSTITUTION:After detecting that a front door has been closed, a stand-by unit 1 comes into a state of being ready for alarm emission if a bonnet and a trunk continue each close signal for the specified time long and output it to the unit, and when a door cylinder is operated with a key, it comes to a stand-by state for alarm emission. When anything unusual in regard to theft that the door, the bonnet, etc., are unlocked with a way other than the key and a car body is tilted to some extent due to tire stealing or the like happens there, an abnormal signal is inputted into the stand-by unit 1 from a trouble detector 2. When the stand-by unit 1 is in its stand-by state and the trouble detector 2 outputs the abnormal signal, an alarm device 3 emits a warning signal by a command out of the stand-by unit 1. |
