So, once upon a time someone forgot the combination for their suitcase… and they have something that they really, REALLY need so, what do they do? I’ll tell you. First, get your suitcase, this isn’t going to do you any good if you don’t have your suitcase. Second, get a magnifying-glass (or just use your eyes) and look at the combination lock, now take a good look at the right side of one of the digits, now keep moving it until you see a little black dot next to it, then move on to the next one and do the same thing, repeat for the last one and voila! you have cracked it. If you didn’t get that then just watch this video: How to crack a suitcase lock
How To Break A 3 Digit Combination Lock
Combo Lock How To Open
The 3-digit combination locks used on suitcases are designed so that you can change the combination to a unique code which only you know. To do this, you have to first set the lock to the current combination. You then press a small button (normally using a ballpoint pen) which frees the numbered thumb-wheels from the locking mechanism. The page responds with the first digit of the combination and two possible digits for the last digit. The video above from Samy Kamar shows how you can crack any Master combination lock within.
