る。Cylinder locks are often used as locking devices for hotel guest room doors, but especially in foreign countries, when introducing a guest, the 7 cylinder locks are opened with a duplicate key, resulting in a total of 8 kW people.
Q7) There are times when overseas travelers experience that the security of traveling abroad is harmed due to accidents in which people infiltrate their homes. Accidents like this would be fine if there were no duplicate keys, but as long as we continue to use the locks provided by hotels, eliminating the existence of duplicate keys is practically a national disaster. For these reasons, it is possible to reliably prevent the built-in locking device from being unlocked with just 11 simple operations, and the structure is logical! The IC is inexpensive and can be easily carried by overseas travelers. It is desired to develop a device that prevents unlocking.
