Just some more info, even though marked solved.
If memory serves me correctly, the tool is nothing more than a shim. It is inserted between the dials. As they are rotated, you would feel for the flat spots on each wheel. Once they are all on the flat spots, you move all the dials together (or the one number higher or lower all the way across) till it opens. You still have to have the change key to set a new combo.
Have you tried the factory setting? Probably all 0's.
