An interconnect mechanism is provided for a dual lock of the type having a deadbolt, a deadbolt driving mechanism, a latch bolt, and a latch bolt driving mechanism with an inside handle. The interconnect mechanism includes a base plate adapted to be mounted to an inner side of a door. The base plate includes a flange wall on an outer face thereof which faces away from the door. The base plate further includes a wing on each of two lateral sides thereof, the flange wall including a top face, a lower portion, and an upper portion. A lower cam is rotatably mounted to the lower portion of the flange wall. The lower cam is operably connected to the inside handle to rotate therewith. The lower cam includes a lobe located above the top face of the flange wall. An upper cam is rotatably mounted to the upper portion of the flange wall. The upper cam is operably connected to the deadbolt driving mechanism. The upper cam includes a lobe located above the top face of the flange wall. A slide plate includes a vertical slot in each of two lateral sides thereof. Each vertical slot is extended through by an associated wing on the base plate, thereby allowing vertical sliding motion of the slide plate relative to the base plate. The slide plate includes an upper operative end operably connected to the lobe of the upper cam and a lower operative end operable connected to the lobe of the lower cam. Rotational movement of the inside handle causes rotation of the lower cam, vertical sliding movement of the slide plate, and rotation of the upper cam, thereby retracting the deadbolt and the latch bolt simultaneously.
