Abstract
A key unit includes a control unit configured to control locking and unlocking of an object by performing radio communication with a locking/unlocking device. The key unit is configured to transmit a predetermined signal corresponding to whether a radio wave intensity in the radio communication with the locking/unlocking device is equal to or greater than a predetermined intensity to a mobile terminal. The predetermined signal is used to transmit a predetermined notification to a user when the predetermined signal is received by the mobile terminal.
