This page gives you two complete examples, from start to finish, of cracking a Master lock.  These example aren't just information I randomly took from my head, I had two Master locks in front of me that I cracked while writing this.  I like the two 'Method 2' methods and I will use them for this example.  If you haven't learned them yet, you should, it will make cracking locks a lot easier and quicker.

Example 1:

I take the lock I want to crack and I make a table like I stated on the '3rd# Method 2' page.  It looks like the following:

Columns B and C can be eliminated since all the decimals of the low part of the ranges are the same, as well the high end decimals.  The first row of numbers in column A has different decimals than the rest, so the third number of the combination of this lock is between 1.75 and 2.5, which makes it 2.  When I was writing this data down, I noticed this discrepancy and knew that the number had to be 2 all along.  Furthermore, the table isn't even needed and it can be clearly seen that the arc is different around 2 when turning the dial (if I were doing this by eye).

I solve the third number in the combination modulus 4 to get 2 (2%4=2 because 2 divided by 4 is 0 with a remainder of 2).

I rotate the dial of the lock a few times to the right to reset it.  I rotate the dial right until I get to 2.  I rotate the dial one complete turn left, and carefully stop it on 2 again.  I rotate the dial six more notches to the left to 8.  Normally I would rotate it two notches to 4, but we know that the third number +/- 2 can never be the second number.  I rotate the dial right to 2.  I try to open the lock, but it doesn't open, so I turn the dial left to 12 (8+4=12).  I rotate it right to 2 again, but it won't open.  I rotate the dial left to 16 (12+4=16), then right back to 2, then try to open it again but it won't work.  I continue doing this until I rotate the lock left to 28 and back right to 2, at which point the lock opens.  This lets me know that the middle number is 28.  Since I started from 2 (then added notches) I know that the first number is 2.  Thus the combination to this lock is 2-28-2.

Example 2:

I try to get the third number of the combination and get a table that looks like the following:

Columns A and B can be eliminated since all the decimals of the low part of the ranges are the same, as well the high end decimals.  The third row of numbers in column C has different decimals than the rest, so the third number of the combination of this lock is between 27.75 and 28.75, which makes it 28.  When I was writing this data down, I noticed this discrepancy and knew that the number had to be 28 all along.  Furthermore, the table isn't even needed and it can be clearly seen that the arc is different around 28 when turning the dial (if I were doing this by eye).

I solve the third number in the combination modulus 4 to get 0 (28%4=0 because 28 divided by 4 is 7 with a remainder of 0).

I rotate the dial of the lock a few times to the right to reset it.  I rotate the dial right until I get to 0.  I rotate the dial one complete turn left, and carefully stop it on 0 again.  I rotate the dial two more notches to the left to 2.  I rotate the dial right to 28.  I try to open the lock, but it doesn't open, so I turn the dial left to 6 (2+4=6).  I rotate it right to 28 again, but it won't open.  I rotate the dial left to 10 (6+4=10), then right back to 28, then try to open it again but it won't work.  I continue doing this with left turns to 14, 18, 22, 34, and 38 (but 26 or 30 since they are 28 +/- 2).  After doing this the lock doesn't open so I know the first number of the combination is not 0.

I add 4 to 0 to get a total of 4.  I rotate the dial of the lock a few times to the right to reset it.  I rotate the dial right until I get to 4.  I rotate the dial one complete turn left, and carefully stop it on 4 again.  I rotate the dial two more notches to the left to 6.  I rotate the dial right to 28.  I try to open the lock, but it doesn't open, so I turn the dial left to 10 (6+4=10).  I rotate it right to 28 again, but it won't open.  I rotate the dial left to 14 (10+4=14), then right back to 28, then try to open it again but it won't work.  I continue doing this with left turns to 18, 22, 34,38 and 2 (but 26 or 30 since they are 28 +/- 2).  After doing this the lock doesn't open so I know the first number of the combination is not 4.
