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.

A portable hoop lock comprises a lock body that accommodates an electromechanical locking mechanism; and a hoop that has at least one locking section that can be selectively introduced into the lock body or released from the lock body, wherein the locking mechanism comprises at least one latch and an electric motor for driving the latch, wherein the latch is configured to lock the locking section of the hoop introduced into the lock body to the lock body in a locking position and to release the locking section of the hoop for a removal from the lock body in a release position. In this respect, the electric motor is configured to selectively move the latch from the locking position into the release position via a drive transmission section of the locking mechanism and the lock body has a watertight cover that surrounds the electric motor.

Apparatus for attaching a lockbox used for retaining a key to a door opened by the key to a door handle and especially a door lever used to open and close the door. The apparatus includes two arms each having a head portion and a bottom portion below the head portion. The arms have an open state in which the head portions are at least partly separated from one another, and a closed state in which two different-sized apertures are defined between the head portions and separately receive the door handle. The arms are positionable around the door handle or removable from such a position when in the open state. The arms are maintained in the closed state and movement thereof from the closed state to the open state is prevented by inserting a shackle of the lockbox through a staple engaged with both arms.

Apparatus for retaining a key on a door handle or lever. The apparatus includes two arms each with a head portion and a bottom portion having a shackle prong extending in a direction away from the head portion. The arms have an open state in which the head portions are at least partly separated from one another, and a closed state defining an aperture therebetween. A key box has a compartment for containing the key, and receptacles that receive the shackle prongs when the arms are in the closed state. The key box transitions from a closed state in which the shackle prongs are locked in the receptacles to an open state in which the shackle prongs are out of the receptacles upon entry of a shackle release code. The key box enables access to the compartment upon receiving an access code different than the shackle release code.

A padlock having a removable or interchangeable shackle is disclosed. The padlock comprises a lock body and a shackle, the shackle being movable in an axial direction between a locked position and an unlocked position, the short leg being withdrawn from the lock body in the unlocked position. The padlock also comprises a retaining shaft receivable within a corresponding bore of the lock body, wherein the long leg includes a longitudinal recess for providing a travel path for the movement of the shackle from a locked position defined by the retaining shaft engaging a first end of the longitudinal recess to an unlocked position defined by the retaining shaft engaging a second end of the longitudinal recess to prevent the shackle from being removed from the lock body when the shackle is in the unlocked position.

A padlock configured to be locked and unlocked by a key includes a key-retaining cover. The padlock includes a lock body having an internal cavity with a locking mechanism received therein. The locking mechanism is a linear lock configured to receive the key through a keyhole to lock and unlock the padlock. A direction of insertion of the key into the locking mechanism is parallel with a direction of displacement of a plurality of tumblers in the locking mechanism thereby creating an outward ejection force on a fully-inserted key. The cover is disposed on the locking mechanism proximate the keyhole. The cover is configured to retain the key in position relative to the locking mechanism against the outward ejection force after the key is received in therein.
