A locking device and a method for unlocking the locking device are provided. The locking device includes a stationary plug having a first aperture extending therein configured to receive a key. The stationary plug further includes an outer surface, an inner surface defined by the first aperture, and at least a second aperture extending from the outer surface to the inner surface. The locking device further includes a housing having an outer wall disposed around at least a portion of the stationary plug. The outer wall has at least a third aperture extending therethrough. The locking device further includes a bolt member operably coupled to the outer wall of the housing. The locking device further includes a locking mechanism disposed in the third aperture of the housing and extending into the second aperture of the stationary plug. The locking mechanism is configured to allow rotation of the housing about the stationary plug when the key is inserted into the first aperture. The housing is configured to rotate from a first operational position to a second operational position in response to a force being applied to the bolt member.
