Many combination locks have three numbers associated with them. A combination lock that has the middle spinner unlocks like this: Turn the dial to the left past the first number and then to that number the second time. Then turn the knob to the right to the second number. Finally turn the knob back to the left to the third number. This unlocks that type of combination lock.
There is a spot on the back of this lock that can be drilled out with a tiny drill bit. By looking through this hole, you can see three different plates that will line up with each other when the combination is correct. Some locksmithes even have lock codes for these locks but the books that have these code are very expensive and if it is just some cheap lock, it just doesn't pay to pay a locksmith ten bucks or more for the code when you can buy a new lock for five.
Example: Your combination is 25 11 33
Turn to the right 3 times stopping at your first number, which is in this case 25.
Then turn one full turn to the left stopping at the second number.(11)
From there, turn to the right to your last number.(33).

A combination lock has none of those features and thus can't be picked. The best way to bypass a master lock is with shims. That's the easiest method.
