Abstract: A wall panel system for finishing a wall or ceiling with a panel frame extrusion for joining the panel face and panel back skin of the panels. The panel frame extrusion has a keyway into which key anchors are received in latched and unlatched orientation. When the key anchors along adjacent sides of a panel are in latched orientation and the key anchors along the other sides are in unlatched orientation, the panels may be arranged such that a panel in a row and column may be removed without replacing the surrounding panels.
