Abstract:
1. A method of facilitating the use of a lock, including the step of providing a key body for use with an associated lock core including a sleeve defining an interior region and a finger-receiving notch, a core plug positioned in the interior region of the sleeve to permit rotational movement of the core plug relative to the sleeve, the core plug defining a longitudinally extending keyway and a side pin assembly passage, the side pin assembly passage being positioned adjacent to the keyway, and a side pin assembly including a side pin and a region pin separate from the side pin and positioned longitudinally adjacent to the side pin, the side pin assembly being positioned in the side pin assembly passage to move in a longitudinal direction between a first position blocking movement of the core plug relative to the sleeve and a second position permitting movement of the core plug relative to the sleeve, at least a portion of the region pin being positioned in the keyway, the side pin including a finger positioned substantially in the finger-receiving notch of the sleeve when the side pin assembly is in the first position and positioned substantially out of the finger-receiving notch when the side pin assembly is in the second position, a substantially cylindrical body portion, and an arm extending rearward from the body portion, the finger extending transversely from the arm of the side pin, the substantially cylindrical body portion of the side pin having a central axis and the arm of the side pin having a central axis that is parallel and offset from the central axis of the substantially cylindrical body portion of the side pin, the key body associated with the lock core including
