PROBLEM TO BE SOLVED: To enhance the effect of preventing illegal intrusion such as sneak-thievery and robbery by generating an odor and a color for specifying an invaded house upon the operation of an alarm device for preventing damage by lock-picking crimes, and causing the odor and the color to adhere to a criminal who intruded the house so as to specify the criminal. SOLUTION: A means for sprinkling a color bag or the like with an odor for specifying an invaded house is provided together with an alarm device, for preventing illegal unlocking of an existing keyhole. In the event of illegal unlocking by picking, the color bag is broken as an alarm is issued upon invasion of a picking tool into the keyhole, producing the unique color from the means, and automatically sprinkling specially designed color balls into an entrance hall and a passage around the keyhole. If stepped on by an intruder, the color balls are broken, ejecting a liquid with the odor, which then adheres to the intruder's clothes and shoes. By analyzing the odor and the color, the invaded house is specified.
