A concealed panel locking mechanism is provided which may be used to secure the contents of a container in a manner that is not discernable to an uninformed individual viewing the container. In one exemplary embodiment, the locking mechanism includes one or more channels formed into a central area of a panel of material. A locking member within the one or more channels is movable along the channel to either engage or disengage the locking member from a recess formed in a side wall of the container. In one embodiment, the locking member is not physically accessible from outside the channel by a human being but is formed from a ferromagnetic material that is moved within the channel by a magnetic force generated by a suitable strength magnetic key placed on the outside surface of the panel.
