Abstract: An axial spring balancing pin tumbler lock includes a cylindrical shell, a plug rotationally disposed within the shell and rotatable by a tubular key. The shell contains a plurality of first pin bores annularly and evenly defined to the axis of the shell for receiving first pins and first springs. The plug has a through aperture for engaging with a elongated spindle, a key bore coaxially defined on front end for receiving the tubular key, a plurality of third pin bores annularly and evenly defined on front end with same depth of the key bore for receiving third pins, and a plurality of second pin bores defined on rear end of the plug for receiving second pins and second springs. Each second pin may contacts the tubular key and one of third pins simultaneously. The extension force of the second spring at its preloaded length is stronger than that of the first spring at its fully loaded length so both second pin and third pin are urged by compound extension force to their most extended position while the first pin is at its most retracted position. The extended third pins bridge the shear plane of the lock, the plug is then blocked from rotating. Since the third pins are isolated from the opening keyway and are not driven by key notches or external force directly, the conventional lock picking or bumping methods must fail.

Abstract: A high security cylinder lock includes a housing comprising a plurality of driver pin bores for disposing spring loaded driver pins; a plug rotatable within the housing comprising a plurality of balancing pin bores for disposing spring loaded balancing pins and a plurality of combination pin bores for disposing combination pins. Each combination pin is sandwiched between a driver pin and a balancing pin. The extension force of the balancing spring at its pre-load length is greater than the extension force of the driver spring at its fully-load length. The compound force causes at least one combination pin partially extended into a corresponding driver pin bore in the housing when the plug is at its first rotational orientation in case of no key engaged. The key profile pushes the balancing pins to move to such position that all mating surfaces of the combination pins and the driver pins to lies onto the shear line of the lock. The balancing pin, balancing spring and balancing spring seal set may be substituted by magnetic balancing pin and magnetic seal pin set.
