MMF2216190G2 SteelMaster® Combination Lock Cash Boxes are security products designed to prevent unauthorized access. You can't reset the combination code without opening the box; and you can't open the box without the combination code. Not without destroying the cash box.
MMF2216190G2 cash boxes are factory set to open with combination "000." However, the factory-set combination will not work if you changed the combination to a private number.
If you can't remember your combination, you can destroy the lock to access the contents of your cash box. SteelMaster recommends prying open the cash box with a flathead screwdriver. Again, this will destroy the cash box, so I wish you luck in remembering your combination!
