A cylinder lock and an associated key, the lock including a fixed body and a plug which is accommodated within a respective cavity of the body and can rotate with respect to the body. The plug includes a substantially longitudinal compartment for the functional accommodation of a key which includes a grip portion from which an elongated body extends and which is provided with coding grooves and protrusions on its outer surface. Between the plug and the body are respective accommodation channels for translating coding elements, which open onto the substantially longitudinal compartment. The plug includes at least one auxiliary duct which faces the substantially longitudinal compartment and extends at least partially in the body for the sliding accommodation of at least one coding unit that includes at least one pin and at least one conical portion.

A cylinder and key lock mechanism is unlocked when a specific combination of rotation angles of dialer groups, each constituted by one internal dialer disc and by one external dialer ring coupled through teeth, is dialed through rotation of the key having a formed cipher. A security mechanism, being part of the key and driven by the insertion of the key into the cylinder, enables re-programming. When unlocked and with re-programming enabled, re-programming is possible where the inner dialer discs are decoupled from the respective outer dialer rings, the key can be rotated driving only the inner dialer discs and extracted leaving the system in a re-programming configuration. A new key having a different cipher can be inserted and the system exited re-programming with a different coupling between the inner dialer discs and the respective outer dialer rings so that they couple with the new key cipher.

A cylinder lock and an associated key, the lock comprising a fixed body and a plug, which is accommodated within a respective cavity of the body and can rotate with respect to the body. The plug comprises a substantially longitudinal compartment for the functional accommodation of a key which comprises a grip portion from which an elongated body extends which is provided with coding grooves and protrusions on its outer surface; between the plug and the body there are respective accommodation channels for translating coding elements, which open onto the substantially longitudinal compartment; the plug comprises at least one auxiliary duct, which faces the substantially longitudinal compartment and extends at least partially in the body, for the sliding accommodation of at least one coding unit that is constituted by at least one pin and at least one conical portion.

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.

A key (1) for a rotary cylinder lock (2) comprises a key grip (3) and a key shank (4), which adjoins the key grip (3) and extends along a longitudinal axis (L), wherein the key shank (4) has, on its outside (5), control recesses (10), in particular control bores, for properly positioning tumblers on the rotary cylinder lock (2) and also has at least one control element (6) arranged in a movable manner in the key shank (4), which control element (6) has a control surface (8), which interacts with a tumbler (7) of the rotary cylinder lock (2). Furthermore, the key is characterized in that the key shank (4), in the region of the control element (6), has a tapered cross section (9), which is tapered in relation to the cross section (11) with the control recesses (10).

A lock assembly includes a plug with a keyway, primary pins aligned with the keyway for controlling rotation of the plug, a sidebar for controlling rotation of the plug, secondary pins adjacent the keyway for controlling movement of the sidebar, and at least one supplemental sidebar control element for controlling movement of the sidebar. The lock assembly is operated by simultaneously manipulating the primary pins, the secondary pins, and the supplemental sidebar control element to place each in a respective position and/or orientation to permit rotation of the plug and to permit sufficient movement of the sidebar to permit rotation of the plug and then applying torque to the plug.

A lock set comprising a cylinder lock having a stator and a rotatable member rotatable in the stator and having a key slot and at least one side; a security element with protrusions, pivotally connected to the rotatable member; and one or more fitting keys, each having one or more recesses and one or more extensible members. The distances between the protrusions of the security element correspond to locations of the recess(es) and extendible member(s) of the fitting key for engagement therewith, such that using the fitting key will have the security element positioned in a non-obstructing position allowing free rotation of the rotatable member in the stator and using an unfitting key will cause a portion of the security element to protrude from the outer wall of the rotatable member engaging the inner wall of the stator thereby preventing rotation of the rotatable member in the stator.

The present invention provides a key blank and a key set. The key blank includes one or more telescopic members inserted through corresponding one or more channels of the key shank for fitting to release a security mechanism of a lock unit. The lock set has one or more fitting keys and a lock unit including: a stator; a rotor; a first locking mechanism; and an additional security mechanism including one or more wafer units. The key shank has one or more telescopic members each inserted in a channel perforated in the key shank. The wafer unit of the security mechanism is located and configured for engaging an edge of the telescopic member when the fitting key is used, such that each telescopic member will move the respective wafer unit it engages for releasing the additional security mechanism for allowing the rotor to rotate in the stator.

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).

A cylinder lock assembly includes a plug rotatable in a cylinder lock body. The plug includes chambers, each of which has a chamber depth axis. A plurality of thin, planar plug locking elements are received in the chambers. Each plug locking element has a key cut interface probe for interfacing with a key cut formed on a key. Each plug locking element is arranged to move along the chamber depth axis and does not rotate about the chamber depth axis. Each key cut interface probe has a predetermined orientation with respect to the chamber depth axis.
