Abstract: Provided is an information processing apparatus including: a locking control unit configured to execute a first process of processes for causing a locking unit to unlock, on the basis of detection of access of a first communication terminal; and a detection unit configured to detect an unlocking request by a user of the first communication terminal. The locking control unit executes a second process of the processes for causing the locking unit to unlock, when the unlocking request is detected and the first process is completed.
