Abstract

A secure lockbox includes an interior key lock that controls access to the mechanism for setting and changing the combination for the lock controlling access to the interior storage compartment of the lockbox. A second key lock controls the attachment bail of the lockbox, preventing unauthorized removal of the lockbox. The two key locks may be identically keyed. In a variant of the invention, a second combination lock controls the attachment bail instead of a key lock. Resilient coverings are provided for the attachment bail and the sides of the lockbox body to prevent damage to buildings and fixtures. A chain is provided to secure the door of the lockbox to the body. A slide latch having non-slip features is controlled by the door's combination lock and engages an edge of the door opening to secure the door opening. The slide latch may have a protrusion for ease of use.
