PROBLEM TO BE SOLVED: To provide a locking/unlocking system and the like that even when authentication information transmitted from a portable terminal to a vehicle or facility is intercepted, are capable of preventing the vehicle or facility from being illegally used on the basis of the intercepted authentication information.SOLUTION: A locking/unlocking system includes a portable terminal and a key unit provided inside a vehicle or facility. The portable terminal comprises a transmission unit for transmitting authentication information and a request signal to the key unit. The key unit comprises: a reception unit for receiving the authentication information and request signal from the portable terminal; an authentication unit that when authentication information is received, authenticates the portable terminal on the basis of the authentication information and, once authentication of the portable terminal based on the authentication information is performed, inhibits authentication of another portable terminal even when the same authentication information is received from the other portable terminal; and a locking/unlocking processing unit that when the authentication of the portable terminal is successful and the request signal is received, performs processing of locking or unlocking a door of the vehicle or facility.SELECTED DRAWING: Figure 1
