SOURCE: Problem with Master Lock 5400
You have 10,000 combinations to go through. Best to cut if off and bring it some place comfortable to try out all of the combinations from 0000 to 9999. Or take it to a machine ship and have someone grind the thing open.
SOURCE: i have forgotten the numbers I set on my lockbox
im pretty sure you do because the little reset button wont move if the combo isnt put in
go to this url for the manual:
