To implement a lock system which is resistant to unauthentic unlocking such as picking, and excellent in terms of security.
The lock system is composed of: a keyhole which has a path space that is large enough for at least the entire key to move therein, and has at least one locking device arranged therein; and a key movable in the keyhole. At the time of unlocking, when the entire key is inserted into the keyhole, the key autonomously moves in the keyhole path to access the locking device set in the keyhole, to thereby unlock/lock the lock device. By virtue of the lock system thus composed, physical arrival at the locking device from outside is not easy, and even if the arrival is achieved, the locking device can be released only when predetermined conditions are satisfied. Thus the lock system is resistant to unauthentic unlocking such as picking, and excellent in terms of security.
