The Magnum is Supra’s most durable mechanical KeyBox in the automotive market. Made from non-corrosive zinc alloy, the Magnum’s sidewalls are 33% thicker than previous KeyBoxes. Utilizing the proven Title™ lock and key system which permits only authorized access, the Magnum is completely compatible with all of Supra’s existing KeyBoxes. Its thicker sidewalls, strengthened locking mechanism, and recessed lid design all contribute to Magnum’s durability. The large key compartment is perfect for holding large keys. Magnum utilizes the Title® key system to bring you Kidde’s one-key convenience. Title keys are cut in-house through a proprietary method that cannot be copied.
