a mobile terminal;
a central server connected to the mobile terminal so as to communicate with the mobile terminal; and
a key unit that is connected to the central server so as to communicate with the central server and that controls the state
of a lock,
wherein the mobile terminal has a positional-information detecting unit capable of detecting its own position, and automatically
transmits a first email for requesting notification of the state of the lock to the central server when the mobile terminal
is outside a predetermined area including a specific position specified by a user, and
