Click For Summary
The discussion focuses on cracking Master Combination Locks by analyzing the relationships between the three numbers in a combination. It highlights that the first and third numbers share a modulus 4 relationship, while the second number is related to the third number by a modulus 4 difference of plus or minus 2. Four tables are presented that outline possible combinations based on these relationships, significantly reducing the total number of valid combinations from 64,000 to 4,000. Participants confirm the effectiveness of this method, with one user successfully opening their lock by referencing the tables. The conversation emphasizes the practicality of using these mathematical relationships to simplify the process of finding combinations.

Cracking Master Combination Locks



I've come across the following information:

The three numbers in the combination to a Master Combination Lock have the following relationships:

The first number modulus 4 = the third number modulus 4;

and

The second number modulus 4 = (the third number modulus 4) +/- 2.


If this information is correct, the following tables showing possible numbers in a combination should be valid:

Code:
Table 1

1st Number Possibilities  1  5  9 13 17 21 25 29 33 37
2nd Number Possibilities  3  7 11 15 19 23 27 31 35 39
3rd Number Possibilities  1  5  9 13 17 21 25 29 33 37


Table 2

1st Number Possibilities  3  7 11 15 19 23 27 31 35 39
2nd Number Possibilities  1  5  9 13 17 21 25 29 33 37
3rd Number Possibilities  3  7 11 15 19 23 27 31 35 39


Table 3

1st Number Possibilities  2  6 10 14 18 22 26 30 34 38
2nd Number Possibilities  0  4  8 12 16 20 24 28 32 36
3rd Number Possibilities  2  6 10 14 18 22 26 30 34 38


Table 4

1st Number Possibilities  0  4  8 12 16 20 24 28 32 36
2nd Number Possibilities  2  6 10 14 18 22 26 30 34 38
3rd Number Possibilities  0  4  8 12 16 20 24 28 32 36



The number of possible combinations to a Master Combination Lock is 64,000 ( = 40 x 40 x 40).


If the above four tables are valid, the number of possible, valid combinations is only 4,000 ( = 4 x (10 x 10 x 10)).


Still a considerable number; however, it's reduced by a factor of 16.


Before going further, I would like to confirm the above four tables show all valid, possible combinations to Master Combination Locks.

If you have a Master Combination Lock, would you compare the combination to the lock against possibilities in the tables?

Does the combination to your lock appear as a possibility in the tables?

Mine appears as a possibility.
 
ye i found mine...i had fprgotten my combo but i new that my second number was 30 so i looked for the table with 30 in #2 and then i just went with the low numbers for the first and third combos and it opened thanx
 
yeah it works man.
there are several website about this.
once u have used the sticky points method to find the last number, there is only like something like 64 combinations and u can easily go through these combinations to find it out.
