PROGRAMMABLE LOCK CYLINDER ASSEMBLY

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 5 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 10 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 15 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.
