Abstract: A locking apparatus according to an embodiment includes an approach detector, a signal transmitter, a measurer, and a controller. The approach detector detects an approach of a user carrying a terminal. The signal transmitter transmits a key authentication signal for authenticating a pre-shared digital key to the terminal using first short-range wireless communication when the approach of the user is detected. The measurer connects a session by generating a security channel with the terminal using second short-range wireless communication and measuring at least one of a distance to and an angle with respect to the terminal when the digital key is authenticated through the key authentication signal. The controller determines whether or not to unlock an access facility in accordance with at least one of the distance to and the angle with respect to the terminal.
