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).

An electronic lock includes a housing, and a locking system within the housing. The locking system includes electronics and a lock. More particularly, the housing contains therein, a controller and at least one electronic input device electrically coupled to the controller, where the controller causes the lock to transition between a locked position to an unlocked position responsive to input from the electronic input device.

A tubular lock assembly has a tubular lock, a cover, and a disassembling unit. The tubular lock has an annular keyhole and a cover screw hole enclosed by the keyhole. The cover is detachably assembled with the tubular lock, and has a covering board segment, a screw rod segment, and a first fitting segment. The covering board segment covers the keyhole. The screw rod segment is detachably screwed in the cover screw hole of the tubular lock. The first fitting segment is formed on the covering board segment. The disassembling unit has a second fitting segment. The second fitting segment corresponds in shape and size with the first fitting segment of the cover, such that the second fitting segment is adapted to engage with the first fitting segment, and the disassembling unit is capable of rotating the cover.

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.

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.

Systems, methods, and apparatus are disclosed involving a door blocking apparatus to reduce a likelihood of, and possibly prevent, opening of a door by unauthorized personnel. The apparatus may be networked in a security system and may be connectable to an online security platform. In a particular embodiment, an embodiment of the invention may include a security system involving a plurality of door locations having a plurality of networked door blocking apparatus. Each door blocking apparatus may include a door blocking mechanism operable by a user on a safety side of a door, such as having the user rotate an apparatus handle that rotates the door blocking mechanism between a non-blocking position and a blocking position. In the non-blocking position, the door blocking apparatus does not block the door from opening and closing. In the blocking position, the door blocking apparatus blocks the door from opening and from closing completely.

Systems and methods are disclosed that operate a door latch of a door of a heating, ventilation, and/or air conditioning (HVAC) system electronically based on operating a locking engagement device. The locking engagement device may be disposed on an outer portion of a door, the latch may be part of a latching system disposed on an inner portion of the door, and the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to the latching system via a conductor electronically coupling the locking engagement device and the latching system. In some embodiments, the locking engagement device may transmit a signal indicating that the locking engagement device is in an open or closed position to a controller, which may then instruct the latching system to open or close the latch based on receiving the signal.

The invention relates to an actuating handle (100) for a door with an escutcheon (104) and a handle (102) for actuating a locking device arranged in the door. The handle (102) for actuating the locking device is mounted in the escutcheon (104) rotatably about a first axis of rotation. The actuating handle (100) moreover has a blocking device (106), having a release position in which a rotation of the handle (102) about the first axis of rotation is released, and a blocking position in which a rotation of the handle (102) about the first axis of rotation is blocked by the blocking device (106). The actuating handle (100) moreover has an actuating mechanism (112) for the blocking device (106). According to the invention, it is provided that the actuating mechanism (112) has a sliding element (108) which is displaceable along a circle segment centered around the first axis of rotation, wherein a displacement of the sliding element (108) along the circle segment brings about an actuation of the blocking device (106).

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.
