As you turn the dial CW with tension on the shackle, you will come to the first clockwise stopping point where you can’t turn the dial anymore. Make note of where it stops. Sometimes, the dial will stick right on the numbers, but sometimes the sticking point will be between the numbers. If so, record the number to the half (example: 22. 5). [3] X Research source While continuing to apply tension to the shackle, turn the dial as far left (counter-clockwise) as you can. Make note of the first counter-clockwise (CCW) stopping point. The CCW stopping point and CW stopping point form your sticking “range”, for example, 22. 5 to 10. (Note: Some 800XXX and 908xxx locks have a two number sticking range [for example, 28 to 30 and 10 to 12]. )[4] X Research source Determine the first sticking point by finding the number that’s in the midpoint of the sticking range. A range of 4 and 5 would have a first sticking point of 4. 5. A range of 22. 5 and 23. 5 would have a first sticking point of 23. Each set of numbers that you find will have the same range. For example, one group may be 0. 25 to 0. 75 and another may be 0. 5 to 0. 25 on either side of the sticking points.
Look at your list of sticking points and eliminate all those which are not whole numbers (that is, cross off any number that ends in 0. 5). You should eliminate 7 of the 12 numbers with this step. Of the remaining sticking points, choose the number with the unique digit in the “1s” position. Four of the remaining 5 numbers will share the same number in the “1s” place, so for example, if the numbers left on the list are 4, 14, 24, 27, and 34, the number 27 is the only number which does not have a 4 in the “ones” place. This is the third number of the combination. If you only have four numbers remaining and they all share the same digit in the “1s” position, check the “note” above in step 3 about a 2-number range. . . the third number of your combination will be the number that has a 2-number range (for example, if you have 0, 30, 20, 10 left, but 20 has a range of 19 to 21, that would mean that your third combination number is 20).
In this case 27/4 = 6 remainder 3. Remember that you are only concerned with the remainder, which will always be 0, 1, 2, or 3. If the third number of the combination is less than four, that is your magic number. The remainder is the magic number. Write it down.
Add 4 to the magic number (3). Write down the result (7). Now add 4 to that and continue adding 4 to each resulting sum until you have gone completely around the dial once. Write down each of these numbers. For the example above, the numbers would be 3, 7, 11, 15, 19, 23, 27, 31, 35, and 39. One of these numbers is the first number of the combination. (Note: For some 800XXX locks, this will be the second number of the combination. The next set of numbers will be used as the first)
Since the example magic number is 3, subtract 2 and get 1. Write down the answer and add 4 to it. Now add 4 to each resulting sum until you have gone completely around the dial once. In the example, the numbers would be 1, 5, 9, 13, 17, 21, 25, 29, 33, and 37. One of these numbers is the second number in the combination.
