A key device (10) includes a generally elongate shaft portion (12) including a key combination surface (16) that has a plurality of key cut stations (18) for forming telescoping key cuts at each key cut station (18). Each key cut station (18) has a telescoping maximum adjacent cut specification (MACS) that defines a maximum depth of adjacent. The key device (10) also has a non-MACS key cut (20), formed at one or more of the key cut stations (18), for interfacing with a first pin (24) of a given telescoping plug pin. The non-MACS key cut (20) is dimensioned to leave material in the elongate shaft portion (12) for forming another key cut (20A) for interfacing with a second pin (26) of the given telescoping plug pin.

A cylinder lock with a rotating tumbler pin, a sidebar, and a slider has a keyway with a ward projection into the center of the bitting area of a key blade received by the keyway. The tip of each rotating tumbler pin seats on the bitting surfaces remaining to the sides of this center ward of the key, and the tumbler pins that are engaged by the bitting on the side of the key blade do not seat on more than half of the width of the blade. Half the pin width is removed from each tumbler pin near the tip thereof. The key has a bitted section at which one or more bittings are formed and a non-bitted section bitting that is devoid of bitting. The bittings extend at a constant depth to an edge of the key blade.

A key device (10) includes a generally elongate shaft portion (12), and at least one magnetic key combination element (20) disposed in the shaft portion (12), which is rotatable about a rotation axis (22).

The key (1) for a lock (2), comprises at least a lever (9) having a first arm (10) for starting movement and a second arm (11) for activating a tumbler element of the lock (2), the lever (9) being pivoted to the shaft (4) of the key (1) with an oscillating axis thereof being transversal to the longitudinal axis of the shaft (4) of the key (1), the first lever arm (10) and the second lever arm (11) being located on a same face (5) of the shaft (4) of the key (1).

The disclosure relates to an improved cylinder lock, key and their combination. More specifically, the disclosure relates to a locking pin assembly operable to provide added combination and increase security against burglary, such as by key bumping, a cylinder lock incorporating the locking pin assembly and key blade and key blade assemblies having the configuration to actuate the locking pin assembly.

Provided are a lock cylinder and an unlocking key. The lock cylinder includes: a lock housing; a lock core, herein the lock core is rotatably arranged in the lock housing; a locking member, herein the locking member is movably arranged between the lock core and the lock housing and provided with a locking position and an unlocking position; a locking blade, herein the locking blade is movably connected to the lock core and capable of stopping or avoiding the movement of the locking member so as to lock or unlock the locking member; a driving assembly, herein at least part of the driving assembly is movably arranged relative to the locking member, and the driving assembly is capable of stopping or avoiding the movement of the locking member so as to lock or unlock the locking member.

A fabrication system is disclosed for use in a key making machine. The fabrication system may have a housing with a slot configured to receive a key blank, and a receiving unit configured to accept a shank of the key blank at the slot. The receiving unit may be configured to mechanically align the shank as it is inserted by a user. The fabrication system may also have a clamp movable between an open position and a closed position, and an actuator. The actuator may be configured to move the receiving unit and the key blank to the clamp, and to move the receiving unit away from the key blank after the clamp has moved to the closed position.

A key device includes a generally elongate shaft portion that has first and second oppositely directed side surfaces, at least one of which is cuttable to form key cuts that define a key combination surface. First and second key combination elements, disposed in the elongate shaft portion, are side-by-side one another at different lateral positions along the width of the elongate shaft portion and located at overlapping longitudinal positions along the length of the elongate shaft portion. The first and second key combination elements are each pivotable about a pivot axis.

The disclosure relates to a cylinder lock wherein an eccentric barrel pin assembly with two contact points within the keyway are independently movable within the barrel to a common shear line against a single nested column pin assembly.

An identification module is disclosed for use in a key making machine. The identification module may have a key receiving assembly configured to receive only a shank of an existing key. The identification module may also have a tip guide, configured to receive a tip of the shank of the existing key. The tip guide may have a slot that exposes a tip end of the shank. The identification module may also have an imaging assembly configured to capture an image of the tip end through the slot.
