A real estate security device for controlling access to premises by realtors. A housing having a shackle lock is removably locked to a door handle of the premises. A barrier precludes access to the shackle from an interior of the housing. A portal communicates the housing interior with an area outside through a sliding door. A door lock independent from the shackle lock opens the door to the housing to allow access to contents of the interior where a premises key can be located when the premises' owner wishes to allow access to the premises.
