Abstract: 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.
