  1. just did this for fun and it worked! what the heck?!

  2. Bolt cutter…SNAP……..DONE!!!!!!!!!!!!!!!!!!

  3. It worked thank you!

  4. Does this work on the Master Lock 1525 locks?
    They require the first number to be entered 3 times, the second twice then the third only one.
    I haven't yet tried doing it only once for each.

  5. I can't find a resistance point between 0 and 11 on my lock. There is a small bump at 8, but the only spot where it actually gets locked in between two numbers so I can't turn it anymore is between 36 and 38. Any idea what might be wrong?

  6. WOW       it worked     thanks

  7. Awesome video! got it on the first try

  8. Hello Sammy, it's me again lol. I just bought a new Purple colored master lock anti shim. It looks the same at the standard black ones. However there are a few differences and makes it impossible for me to crack using any method. The physical differences are 1, they are in a line up of colors. 2, the "hardened" wording on the top of the shackle is larger text. 3, the word "master" on the dial is etched in, unlike the standard white paint. The combination is 3,28,37. Unlike all other master locks I have that are ether all odd or all even. It has NO resistance location, only that it gets harder to push at 0, but no bump. The two whole numbers from 0-11 are 3 and 10. Even if you input those into your tool, you will never get the correct combination for some reason. I would highly recommend getting some of these locks and taking a look. I am trying to help you get a tool that works for these ones too. :)

  9. THIS TOTALLY WORKS!! Forgot my gym lock combo from last year. Took me about 30 minutes. Saved me buying a new lock.
    Thank you Sammy.

  10. Hey Sammy. Got a question for you. Is there a method / mathematical formula to figure out the 3rd digit if you knew the 1st and 2nd? Thank you!

  11. Holy crap thanks! This one actually worked for me

  12. this vid has no use, sorry…………………………………………………………………………………………………………………………………………………………………………………….

  13. Thanks sammy definitely worked. Took a while but i had to make sure i get my first two lock positions correctly. 

  14. That was awesome! Thanks for the time you put into figuring the algorithm out and making an easy to use website!

  15. HA! This is awesome!

  16. nope it doesn't work either way on Hardened locks every time my lock gets stuck in between 35 and zero.
    nothing else happens

  17. Man I tried and tried and nothing
