Hello everyone!! This is my first instructable and I hope you like it.( please comment)

 In this instructable I will share how to crack a masterlock padlock in 100 tries or less.( Helpful if you lost your combination)


FACT: most master\lock padlocks have around 64,000 possible combinations.

ANOTHER FACT: this instructable ( if done properly) will turn 64,000 into 100.

so go to step 1 and let's get started.

Step 1: What You Need...

1: Masterlock Padlock
2: your brain
3: paper and pencil

Step 2: First Find Your Third Number

  To find your third number reset the lock by turning the dial around a few times. Then start at 0 and turn to 3. after that pull the clamp up as hard as you can and move the dial left and right very little. Find a spot after zero and between 5 or 10 that the dial seems to be stuck. take the 2 numbers they stop on and get the middle number.  For example the dial stops on 2 and 3. your number would be 2.5 or if you numbers were 2.5 and 3.5 your number would be 3. write these down. Not the ones I gave you but the ones you get. Repeat this around the dial until you get 12 different numbers. You have to get twelve or it wont work.

                                                                                             example list

2.5
6
9.5
13
16
19.5
22.5
26
22.5
26
29.5
32.5
36
49.5

now that you have 14 numbers take away the ones that have decimal points.
and according to this list
now you should only have
                                                 6, 13, 16, 26, 36.
If you did it right you should have noticed that those 5 numbers have 4 numbers that have the same last digit take those away.


 with this list I am left with 13.
that is my third number.

Step 3: Now You Have to Find Your First Number


  To do this you first take your third number and divide it by four.

with 13 I get 4 remainder1

what you want is the remainder.

now you take your remainder and you add 4 to it until you get the highest number your padlock can get.

my pad lock goes to 39 so here is the example list.
                                                                                            1,5,9,13,17,21,25,29,33,37

those are my possible first numbers

go to the nest step to find your second number.

Step 4: Finding Your 2nd Number

  you just do the same thing but you need to change the starting number.

you do this by changing your remainder.

if your remainder is 0 change it to 2  1=3  2=0  3=1

in my example though you would change it to three since the remainder is 1.

so here are the possible numbers using my example
                                                                                                  3,7,11,15,19,23,27,31,35,and 39

next step will tell you how to find the combinations.

Step 5: Finding Your Combination

now make a list

1st number= 1,5,9,13,17,21,25,29,33,or 37

2nd number=3,7,11,15,19,23,27,31,35,or 39

3rd number= 13



                                                                            NOW MAKE THE DIFFERENT COMBINATIONS

i will give two example combinations per 1st number,

1,3,13; 1,7,13;
5,3,13; 5,7,13;
9,3,13; 9,7,13;
13,3,13; 13,7,13;
17,3,13; 17,7,13;
21,3,13; 21,7,13;
25,3,13; 25,7,13;
29,3,13; 29,7,13;
33,3,13; 33,7,13;
37,3,13; 37,7,13;


         Congratulations if you made this far then you just took 64,000 combination possibilities and reduced it to 100. Try all possible combinations crossing them off if they are wrong until you get the right right combination.
