A cam lock for cabinets, drawers, drug cabinets, credenzas, sliding doors, lockers, mail boxes and other door type applications is compact in size, fits an existing cam lock opening and provides electronic access via a keypad or other electronic access. Using batteries, such as AAA size batteries or smaller, the lock has electronics that release a lock turn knob or handle when the correct code is entered. Preferably a set of electronic contacts is included at an accessible position on the lock housing to allow both master access and power jumping with a common manager's implement, for situations of lost codes and/or battery failure. In a particular embodiment the lock is long, narrow and low in profile so as to fit on the margin of a steel or wood file cabinet, compatible with the cam lock opening already provided. The locks, NFC-enabled, can be used in securing delivery boxes to enable delivery access, when authorized.

An electronic lock includes a latch member and a clutch mechanism mounted on the outside of the lock cylinder and including a clutch unit, a driving unit and a control module. The clutch unit includes a rotatable seat having a first engaging portion, an accessible knob, and a clutch seat having a second engaging portion. The clutch seat is movable relative to the rotatable seat between an unlock position and a lock position, where the second engaging portion engages and disengages the first engaging portion, respectively.

A secure key storage device integrable with an electronic lock having a mechanical key override activation and a mechanical lock. The storage device contains and provides a key which can open the electronic lock on a mechanical override basis via the mechanical lock and is comprised of a locking key caddy compartment which contains the key, and which is provided with a mechanical lock opening member to effect opening thereof. The secure key storage device has a mounting element with a structure configured to be fitted with and securely supported by the mechanical lock of an existing electronic lock on the door and wherein the locking key caddy compartment element is integrated with the mounting element either by fastening elements or as a one piece structure. Alternatively, or in addition a spare battery compartment element is provided with a spare charged battery.

An electronic keeper includes a housing defining a battery chamber and an actuator chamber. An actuator is at least partially disposed within the actuator chamber. The actuator includes a strike and a magnet, and is pivotable between a first position and a second position relative to the housing. The actuator is also biased towards the first position. The electronic keeper also includes a senor disposed within the battery chamber. When a locking element is in contact with the strike, the actuator pivots from the first position towards the second position so that the magnet moves relative to the sensor.

A patch lock assembly releasably secures a glass door to an adjacent glass panel in a locked orientation. The patch lock assembly comprises a latch adapter housing, a strike adapter housing, and first and second power supply adapter housings. The latch adapter housing may interchangeably receive one of any number of various latch mechanisms without requiring further modification of the door. The strike adapter housing may interchangeably receive one of any number of various strikes, including electric strikes, without requiring further modification of the door. Respective power supply adapter housings may be coupled to each latch adapter housing and strike adapter housing. The power supply adapters include a power source and control unit to provide the necessary power to operate the latch and strike. Various interlocking features may be incorporated in the design to resist unwanted movement of the patch lock assembly relative to the glass panel.

An intelligent door lock system provides notification of energy source status. A position sensing device is configured to be coupled to a drive shaft of a lock device. The position sensing device sensing position of the drive shaft assists in locking and unlocking a lock of a lock device. An engine with a memory is provided, with the engine coupled to the positioning sensing device, and a circuit coupled to the engine. An energy source is coupled to the circuit. A server is associated with the intelligent door lock system and provides notification of energy source status.

The present disclosure defines a lever handing apparatus that permits simplified changing of the handing of a lever handle between a left hand and a right hand orientation. The lever handing apparatus includes an assembly with a rotatable spring cage housing and lever spindle that can be selectively rotated within an escutcheon housing to change the handing position of a lever arm. The handing orientation of the lever can be repositioned without removing a back plate or accessing internal components positioned within the escutcheon housing assembly.

A deadbolt lock with an interior assembly having a status light indicator. The deadbolt assembly has a bolt movable between an extended position and a retracted position. An interior locking assembly includes a turnpiece configured to move the bolt between its extended position and retracted position, a light, and a detection circuit. The detection circuit is configured to detect when the bolt is in the extended position and actuate the light responsive to detecting that the bolt being in the extended position.

Proposed is a device for supplying emergency power to a digital door lock, which supplies emergency power by switching a connection method of a battery holder provided in the digital door lock from parallel to series or series to parallel by rotating a door lock opening/closing means.

The invention relates to a child safety locking mechanism 1 for a cupboard or drawer 2 comprising at least one movable door or drawer 3 and a fixed frame 2, and the locking mechanism 1 comprising: a latch assembly 5 and a catch part 4 each fitted on the movable door or drawer 3 and fixed frame, the latch assembly 5 including a latching arm 8 and a latching hook 9, and the catch part including a catch arm 6. The latching hook 9 is aligned to abut against the catch arm 6 in a locked position to prevent the movable door from being fully opened, wherein the latching arm is movable to an unlocked position in which the latching hook 9 is no longer aligned to abut against the catch arm 6 and the movable door or drawer 3 may be opened. Motor driven automatic release means are provided which are remotely actuatable to automatically move the latching arm 8 to the unlocked position when the automatic release means are actuated by a user. The latching arm 8 is moved downwards automatically by the remote actuation of the release arm 20 out of alignment with the catch arm 6. The release arm 20 is mounted on an axle which is rotated by a motor to just a sufficient extent to act on the latch arm 8 to move it out of alignment with the catch arm 6. The latch assembly 5 includes control means for the motor in the form of a circuit board, which also includes a Bluetooth or other radio wave receiver, located in a latch assembly casing 22.
