This video is meant to help you find the combination of an old lock you have lying around. If you are a petty thief, this is not the video for you. There are obviously many other methods to break a lock. No other method will get you the combination however.

So enjoy, and good luck!

  • Who needs math just get the lock cutters

  • @GodDamTruth umm lol? let me take you back to third grade math, you take the highest common multiple of 19 in this case 16 which is 4 x 4 with a remainder of 3 to 19. Now let me take you back to 2nd grade english, remainder*

  • anyone know how to get it to work on a dudley lock :/ cuz this doesnt work on it, it locks at every sticky point a dudley...

  • so the last numbers will always be 0,1,2, or 3?

  • I got my combo using this method on the 27th of 100 tries. In over 40 years of wanting to crack a Master lock while it is locked, I finally did it! If anyone says it's fake, they either didn't try or couldn't follow instructions. Good presentation!!

  • It works!!!!!!

  • Oh shit, it worked.

  • At the beginning when you did 1 divided by 4, is four the number you always use? Or is it the last number for the other four numbers? Because mine end in six so would I use six?

  • THANK YOU!!!!! This worked for me!!! My half numbers went from an integer to a half number, but my all 5 whole numbers went from integer to integer and matched up just like you showed!

  • Right, so I got five decimal numbers and seven whole numbers, and keep on checking, but i get the same numbers

  • Problem I have is figuring out if the lock stops on a whole number or a half in between. A lot of times it moves between a half and the next whole number. For example, from 0 the lock gets stuck between 2.5 and 3, but not 2.5 and 3.5, or 2 and 3. Which is correct: 2.5 or 3? The rest of the lock is the same way. I don't have a lot of movement

    Oh wait, maybe I'm adding too much tension. Releasing it just a bit gave me movement between 2.5 and 3.5 Hmm.
