Proposed invention is an alarm device for protecting various type of locks of premises, buildings, apartments, rooms, vehicles, safes, money terminals and for other objects by means of timely, more early informing, interaction with alarm system or digital-electronic device of persons observing protected object in result of attempts of burglary, unauthorized opening, damaging or even preliminary studying the lock by attacker.

Door lock shielding cover, which includes a shielding cover body, an attraction member, and blocking portions. The shielding cover body is configured to be movably installed onto a lock panel of a smart door lock. The attraction member is installed on a side of the shielding cover body adjacent to the lock panel of the smart door lock. A plurality of through holes is defined in the attraction member. The blocking portions correspond to the through holes in a one-to-one manner. Each of the blocking portions is fixed to the shielding cover body through a connecting portion that penetrates the through hole, thereby fixing the attraction member to the shielding cover body. The fixing between the shielding cover body and the attraction member in the door lock shielding cover is firm and durable.

An insulated door lock assembly including a base member with an aperture for the cylinder of a lock. The base member is configured to be mounted to a door around a hole for the door lock. The inner volume of the base member can be filled with an insulating material. A cover member can be coupled to the base member through a hinge joint. The cover member can be configured to switch between an open state and a closed state. A keyway or a thumb turn of the door lock can be accessible in the open state and the keyway or the thumb turn is covered by the cover member in the closed state. An O-ring can also be provided around a periphery of the base member for sealably engaging the cover member to the base member.

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.

Described herein are example fluid guards that can be used with locking devices. Various aspects may be particularly applicable to electrical locks, but they may also be applicable to mechanical locks. A locking device guard can include a guard head, a guard body, and a hinge. The guard head may include a fluid absorber, a frame that is shaped to receive the fluid absorber, and a fastening mechanism. The guard body can be coupled with an electronic lock. The guard body can include an aperture that is configured to expose a face of the electronic lock.

A handle assembly for an access panel is described and includes a handle connected to a support structure integrated into and covered by a skin of the access panel, the handle comprising a grip portion and upper and lower flanges extending perpendicularly from the grip portion and having first ends connected to the grip portion and second ends connected to the support structure; and a cover disposed over an opening in the access panel skin and selectively transitionable between a closed position and an open position, the opening situated relative to the handle such that the handle is concealed when the cover is in a closed position and accessible via the opening when the cover is in an open position.
