How To Unlock A Master Combination Lock?

Step 1

Rotate the numbered dial on the Master lock clockwise; spin the zero three times past the indicator arrow. Leave the zero under the arrow on the fourth pass. As you raise the shackle clasp, the dial will become stuck and challenging to turn. The dial should be turned clockwise until it stops and won’t spin any further as you raise the shackle clasp. The dial will become stuck after every three or four consecutive digits until it becomes impossible to move. Note the number that is now underneath the arrow.

Step 2

Open the shackle clasp. Spin the dial counterclockwise until it stops, then raise the shackle clasp once more. The range of the third number or last digit of your combination is the separation between the first clockwise spin stopping point number and the second counterclockwise spin stopping point number.

Step 3

On the top line of your scratch paper, write “third number range” downward. Record the number between the two numbers if they are two consecutive numbers; it will be the lower of the two numbers with a 1/2 following it. If the dial pauses between the numbers 3 and 4, for instance, write “3.5” or “3 1/2” on your scrap of paper. Record the middle number, which in this case would be 17, if they are two numbers apart, such as 16 and 18, for example.

Step 4

To advance past the dial’s stopping position, release the shackle clasp. Round the dial three times past zero in the clockwise direction, then stop on zero on the fourth turn. Find the range of the clockwise and counterclockwise spin stopping points, and note the number. Repeat this procedure until the dial has been rotated all the way around to zero. At this point, you ought to have a list of 12 range numbers.

Step 5

Review the 12 numbers on your list. Any number that ends in a 0.5 or a 1/2 should be crossed out because they are not a part of your combination. Examine the range’s remaining numbers. In the single digit or one’s column of four of the numerals, the final digit will be the same. These numbers should be crossed out because they are not a part of your combination. The third number in your combination is the one that is left. On the very top of your page, write “combination third number” and the number you just determined using elimination.

Step 6

Place “second number range” underneath “third number range” on a new line. Write down the remaining next to the potential first number after multiplying the third number by four. There will be a residue of zero, one, two, or three. To the remaining number, add 4. Note down this number. As you circle the dial’s numbers all the way around to zero, keep adding 4 and writing the result down.

Step 7

If any of the potential second numbers are more than two numbers distant from the third combination number, mark them with an X. Any that are two less than the third number of the combination should be crossed out. The second digit in your combo is the last one. At the top of the page, write “second combination number,” then jot down the number you came up with.

Step 8

The first number in your combo should be determined. This can take some time and be a little difficult. Write down the result of adding 2 to the second number. Write down the result of adding 6 to the second number. When choosing the initial number in your combination, avoid using these two digits.

Step 9

Until you locate the first number of your combination, start going through the dial’s numbers one at a time. The first number on the dial that is not two or six more than the second number should be entered. The second and third numbers should then be entered on the dial and rotated counterclockwise past zero.

Step 10

As you continue searching for the first number on the dial, keep in mind to stay away from any digits that are two or six greater than the second number. Write down the combination’s first number next to “first combination number” at the top of your paper when you have it.
