1. A locking device, comprising:
a barrel housing including a first end, a second end, and a barrel including a hollow interior disposed along a longitudinal axis, the second end of the barrel housing including a base coupled to the barrel, the base including a first slot aligned perpendicularly to the longitudinal axis, the first slot including a first surface, the first surface including a channel aligned along the longitudinal axis into the hollow interior of the barrel, the channel including a first circular surface extending along the longitudinal axis of the barrel and a second circular surface disposed adjacent to the first surface along the longitudinal axis, the first circular surface configured with a diameter smaller than a diameter of the second circular surface such that a circular slot is formed at the first surface;
an interchangeable core disposed in the hollow interior of the barrel via the first end of the barrel housing and including a first end and a second end, the first end including a key hole;
a prong driver including a circular plate, at least one prong and an engaging element, the circular plate including a first surface and a second surface, the at least one prong extending from the first surface and the engaging element extending from the second surface, the prong driver disposed in the channel via the second end of the barrel housing and the at least one prong being coupled to the second end of the interchangeable core, such that, the circular plate is rotatably retained in the circular slot and the second surface of the circular plate is flush with the first surface of the base, and
a bolt slidably disposed in the first slot, the bolt including a second slot configured to receive the engaging element of the prong driver,
wherein, when a proper key is inserted into the key hole of the interchangeable core and rotated in a first direction, the engaging element of the prong driver is rotated in the first direction to engage the second slot of the bolt to retract the bolt into the first slot in a direction toward the interior of the base and when the prong driver is rotated in the second direction, the engaging element of the prong driver is rotated in the second direction to engage the second slot of the bolt to extend the bolt outside of the base in a direction away from the locking device.
