I opened my grandfathers briefcase to get a repair kit out and I opened his briefcase by changing the settings (easy since the numbers that were out were tarnished) but then a bit later he told me he couldn't get it open, and he had always kept it unlocked (which was weird, cause it was locked for me.) Anyways, I managed to get one of the 2 locks off, which was the original combination (he didn't know the combination after using the same briefcase for 20 years @_@) But I can not figure out the other, I have put in EVERY possible combination... all 1000 of them (3 reels at 10 each), and none of them worked. I gave up and tried to pick it, but if the combination isn't right, the bar won't move at all. So then I tried to force it, but that would cause severe damage to the briefcase -_-.'''
What can I do now?
