An electronic lockbox uses a rotary actuator with multiple positions to achieve multiple locking states. Multiple positions of the actuator are detected, using optical sensors. The locking mechanism includes an outer sleeve and an inner cylindrical barrel that are coupled with torsion springs. The lockbox has a shackle and a key bin that are retained by the inner barrel when in the locked state, and the barrel can be rotated to either release the shackle or to release the key bin that typically holds a building's key.

Disclosed is a Bluetooth smart padlock, including a lock housing, a lock beam, a lock tab assembly, a power assembly and a sensing switch. The lock housing is provided with a Bluetooth module for establishing a communication with a mobile terminal and a controller electrically connected with the Bluetooth module; the lock beam is partially provided in the lock housing, and provided with a lock tab groove; a lock tab assembly and a power assembly are both provided in the lock housing, wherein the lock tab assembly comprises a lock tab piece, and the power assembly is in transmission connection with the lock tab piece to drive the lock tab piece to extend into or separate from the lock tab groove, to unlock or lock the lock beam; and the sensing switch is provided on the lock housing for controlling the power assembly.

Disclosed herein are various embodiments of an electronic lockbox for storing keys and key cards. The lockbox may include calendar-based entry rules so that the key codes can differ based on the date and time. The lockbox may be controllable by a mobile device such as a mobile phone, tablet, or other mobile device. The lockbox may include functionality so that key codes for the lockbox can be transmitted via websites such as Airbnb, HomeAway, or other rental websites, so that guests automatically receive their unique lockbox codes when they confirm their reservations. The lockbox may also receive a Bluetooth low energy virtual key which may be transmitted directly from a user's mobile phone to the lockbox, so that no manual code entry through the keypad is required by a user. The lockbox may be capable of accepting multiple passcodes enabled at different times and dates, and for different purposes.

There is provided a lock which can include a shackle which can be moved between an unlocked configuration and a locked configuration. A locking mechanism can be carried by the lock. The locking mechanism can include a guard which can be actuated in a manner such that an access region can be defined to facilitate movement of the shackle such that the shackle can be moved to be in an unlocked configuration. The guard can also be actuated in a manner so as to block the access region to impede movement of the shackle when in the locked configuration such that the shackle is maintained in the locked configuration.

Systems, devices, and methods for controlling access to a secure space are disclosed. The system includes a locking device fastenable to an access point of the secure space, a server, and a network for communication between the locking device and server. The server includes a storage unit to store authorization data for the locking device and the user computing device, and a processing unit for receiving a request from the user computing device to access the locking device; authenticating the user computing device; generating authorization data; and providing at least part of the authorization data to each of the locking device and the user computing device. The locking device includes an actuator, a memory, and a processing unit for receiving a security command from the user computing device; determining whether the security command includes requesting data that corresponds to the authorization data; and generating a control signal for the actuator to move the locking device based on the security command.

A portable electronic lock comprises a lock body and at least one securing part, in particular a U hoop or a bolt, that can be selectively locked to the lock body or released from the lock body. The lock body further comprises a first introduction opening and a second introduction opening for introducing a respective section of the at least one securing part into the lock body; an electromechanical locking device that has a first latch and a second latch, a cam rotatable about an axis of rotation and an electric motor for driving the cam; and a control circuit. The first latch can be displaced by means of the cam from an unlocked position into a locked position in which the first latch engages into the first introduction opening in order to lock the at least one securing part in the first introduction opening, and the second latch can be displaced by means of the cam from an unlocked position into a locked position in which the second latch engages into the second introduction opening in order to lock the at least one securing part in the second introduction opening. The control circuit is configured to control the electric motor to drive the cam.
