I have a Kumahira vault door in my home. Mine has a pair of S&G 4 wheel locks. Both tumblers must be operated to open the bolt. There is a very distinct feel to the operation of these tumblers when you reach the final number and reverse rotation you are retracting a mortise that allows the door bolt to operate. Another issue is the time lock. It may have been activated and can only be reset from the inside. Call Pat Bruck at Bruck Safe Company in Columbus, Ohio. He can help you.
