WHY NOT A SHIM?
Shimming is an awesome technique for quickly opening older locks, however all of the newer Master combination locks don't allow shimming: http://www.masterlock.com/businessus...
Also, using this technique recovers the actual combo so you can reuse the lock.

NOTE: If you only find ONE locked position under 11, try to find two locked positions between 10 and 20, and remove the first digit. So if "13" and "17" lock up, enter "3" and "7" as the locked positions into the tool.
