A programmable lock cylinder assembly including a lock housing and a cylinder plug including a keyway extending therein. At least one locking member is moveable in the cylinder plug between a locked position wherein the cylinder plug is rotationally locked relative to the housing and an unlocked position wherein the cylinder plug is rotational relative to the housing. A plurality of pin sets are positioned in the cylinder plug. Each pin set includes a keyway pin component and a locking pin component and is positioned such that a portion of each keyway pin component extends across the keyway. The pin components are selectively engagable. A re-combinating member is engaged with one of the components of each pin set and is moveable between a first position wherein the keyway pin components are engaged with the locking pin components and a second position wherein the keyway pin components are disengaged from the locking pin components. A reset actuator is moveable between an engaged position wherein the re-combinating member position is locked relative to the cylinder plug and a non-engaged position wherein the re-combinating member position is moveable relative to the cylinder plug.

Programmable lock cylinder assembly

A lock cylinder including a housing defining a cylindrical cavity, and a plug disposed in the cylindrical cavity and rotatable between a locked position and an unlocked position. The plug includes an inner pin chamber aligned with an outer pin chamber of the housing when the plug is in the locked position. An inner pin is housed in the inner pin chamber and is engageable with the outer pin when the plug is in the locked position, and includes an outer surface having a non-axial groove. The non-axial groove has a curved surface that defines a substantially semi-circular cross-section. An engagement member is supported by the plug and has a substantially semispherical end portion extending into the non-axial groove such that the semispherical end portion is substantially engaged with the curved surface.

Lock cylinder

A lock cylinder that includes a housing defining a cylindrical cavity, and a plug disposed in the cylindrical cavity and rotatable between a locked position and an unlocked position. The plug includes a key slot and an inner pin chamber aligned with an outer pin chamber of the housing when the plug is in the locked position. An inner pin is disposed in the inner pin chamber for movement along an axis, and is engageable with the outer pin when the plug is in the locked position. The inner pin is engageable by a key inserted into the key slot, and includes an outer surface that defines a non-axial groove. An engagement member is supported by the plug and extends into the groove.
