A portable electronic lock has a lock body having a locking device and a closing hoop that is movable relative to the lock body between a closed position and an open position, wherein the closing hoop can be locked to the lock body by means of the locking device in the closed position. The lock at least has an electrical unit, an electrical energy source, a signal generator, and a control unit. The control unit is configured to monitor a charge level of the electrical energy source and to control the signal generator to output a charge level warning signal sequence in the form of the letter sequence “S-O-S” in accordance with Morse code if the charge level of the electrical energy source falls below a predetermined limit value.

An intelligent door lock system coupled to a door at a dwelling. a door status device is at the dwelling. The door status device is coupled to a drive shaft of a lock device to assist in locking and unlocking a lock of a lock device at the door. The lock device is coupled to the door status device and includes a bolt. An engine, an energy source and a memory are coupled together. A camera is coupled to or part of the intelligent door lock system. The camera is configured to record in response to door lock status.

An electric lock system, includes an electric lock and an electric key. The electric lock includes a lock body and a lock core, and the lock body has a key limit slot and a key limit slide. The lock core includes a T-shaped magnet, a solenoid and a lock pin. The T-shaped magnet is fixed to the lock core, and the lock pin is connected to the solenoid, the solenoid can generate a magnet field when energized, and the magnet field generate a force with the T-shaped magnet, and drives the lock pin to stop limiting the lock body. The electric key includes a lithium battery and a metal housing, and the metal housing has a key limit head corresponding to a shape of the key limit slot. The electric key provides electric power to the lock core by contacting the key limit head to the key limit slot.

A removable lock core for use with a lock device having a locked state and an unlocked state is disclosed. The removeable lock core may include a cam member tailpiece which is moveable between a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which permits removal of the removeable lock core from the lock device which corresponds to the lock device being in the unlocked state. The removeable lock core may include an electro-mechanical drive assembly which in a disengaged state is decoupled from the cam member tailpiece and in an engaged state is coupled to the cam member tailpiece. A cam lock having a locked state and an unlocked state for use with a catch is disclosed.

A door handle assembly that allows for easy removal and switching of handles. Such an arrangement may provide the flexibility to change handle orientation and interchange handles based on a user's circumstances or preferences such as when a door handle is configured as a lever having a curved shape. Further, the door handle may be configured as a door lock having a keypad access control. The face of the keypad accessible from outside the door may include auxiliary battery terminals to provide the user with easy accessibility for providing temporary power to the door lock with an auxiliary battery should the installed batteries housed within the door lock fail to provide sufficient power.

An electronic straight shackle lock apparatus and system. Aspects of the present disclosure provide for a keyless, electronic straight shackle lock that provides a high level of security at a relatively low cost and without any opening for a physical mechanical key. Certain embodiments provide for an easy-to-use and compact adapter for a keyless, electronic straight shackle lock and the ability to manually override the electronic lock. Certain benefits and advantages of the present disclosure include a compact and flexible locking system that can be installed on many different enclosures and doors that can be locked and unlocked using an electronic device via a wireless signal.

Provided herein is a self-contained, self-disinfecting device which automatically disinfects a surface of the device using internally-generated or applied UV (Ultraviolet) light. The device may be a door handle, push plate, light switch, shopping cart, or the like.

A wireless access system at a building is provided. A door lock system includes: a lock status device configured to be coupled to the drive shaft of a lock device, the lock status device assisting in locking and unlocking a lock of a lock device. A processor is coupled to the door lock system. An image capture device at the building is configured to be in communication with the door lock system and capture an image of an object in the vicinity of the building. A light source assembly is in communication with the image capture device.

An electronic lock includes a lock body and a shackle selectively securable via one or more ball bearings. An asymmetric cam can be rotated by a key or an electric motor to: a locked state in which the ball bearing secures the shackle within the lock body via at least one lock notch in the shackle, an unlocked state in which the ball bearing is released from the lock notch to unlock the shackle and subsequently engages a revolved notch on a distal end of the shackle to prevent removal of the shackle from the lock body, and a removal state in which the ball bearing is released from the lock notch and the revolved notch to allow the shackle to be removed from the lock body. A shackle detector can detect a shackle in the locked state. Externally accessible electrical contacts allow for jumpstarting a discharged battery.
