In this paper, we investigate multipartite unlockable stabilized bound entanglement. First, the mathematical structure of these stabilized bound entangled states is studied. Second, since stabilizer states are the local equivalent to the graph states, we study such stabilized mixed states in the graph-state formalism. As a result, the unlockable stabilized bound entangled states can be graphically depicted and decomposed in the product form. Some examples are discussed.
