This is an added security feature to prevent tampering. How it works: Step 2 Press and hold your designated finger combination - Our unique patent-pending design is much like an inverted tumbler lock. Tumbler locks use a key to position tumblers to their proper alignment allowing the barrel to rotate and unlock.

Your hand creates the key that positions these actuators in the correct alignment to unlock the double locked enclosure. Any other combination will keep the StopBox securely locked.
