Abstract
According to one exemplary embodiment, a portion of a lock may include a stationary member having a bore, where the stationary member can be mountable to an object. The portion of the lock can also include a movable member positioned at least partially within the bore and movable relative to the bore in an unlocking direction during a normal unlocking operation. A deformable portion can be positioned adjacent an interface between the stationary member and the movable member. The deformable portion permits the movable member to move in the unlocking direction during a normal unlocking operation and is deformable to prevent movement of the movable member relative to the stationary member when subjected to excessive force applied in an attempt to move the movable member in the unlocking direction in other than a normal unlocking operation.
