2. Clear the Lock
The thumb rule for cracking any lock is to establish a standard point from which you can launch your cracking process. When it comes to the master lock, the starting point is clearing the lock. To clear the lock, you should start by spinning the dial a minimum of three or four times, ensuring you pass the zero mark every time.
3. Crack the 3rd Number in the Combination
After clearing the lock in the cracking procedure, the next step is to look for the 3rd number of your combination. This may sound a little bit odd. You could be wondering why not start by cracking the first number in the combination.
4. Find the 1st Sticking Point
While rotating the lock’s dial in the anticlockwise direction as per the step above, you will find yourself reaching a point where you cannot rotate the dial freely. You will notice that the dial is stuck in a groove between 2 numbers.
5. Find the 2nd Sticking Point
Having found the first sticking point, our next objective is to get the second one. To achieve this, you have to start by releasing the shackle tension and then turning the dial slightly clockwise past the 1st sticking point, 6 or 6.5 in our example above.
6. Find the Rest of the Sticking Points
Having obtained two of the twelve sticking points, you need to look for the remaining ten by repeating the same procedure to crack the 3rd number in the combination. Ensure that you record all the sticking points as you had done with the first two.
7. Crack the 1st Number in the Combination
As aforementioned, cracking the other numbers leaves you with ten possibilities. To begin with, you have to divide the distinct number or the third number by four. In our case, it is dividing 29 by four. When you have divided, your concern shall be the remainder which is 1.
8. Crack the 2nd Number in the Combination
Having cracked the first number, you should be able to crack the 2nd number. To crack the 2nd number of your combination, you go back and check the remainder you used in the above step. In our case, the remainder was one. You are supposed to add two to one (1+2).
