If the set lever on your Master Lock Safe Space Portable Storage Box # ML5900D is not wanting to budge then you either don't have the current combination set or the set lever is seized up. If you forgot the combination and the dials have been scrambled then the only way for you to reset it is to manually go through various combinations until you guess the correct one. Aside from that you'll have to replace the unit.

If you do end up getting the correct combination but the set lever is seized up then I recommend using a spray lubricant like WD40 to try and help loosen up the set lever. You may need to apply the lubricant more than once and it might take some force still to get the lever to move is it is seized up.
