Crack open any Master combination lock in 8 combinations or less! This online tool and new technique will allow you to learn the combination of any Master combo lock with only eight attempts maximum: samy.pl/master/ By Samy Kamkar 2nd part (explanation) here: youtu.be/qkolWO6pAL8 3rd part (Motorized Combo Breaker) here: youtu.be/YcpSvHpbHQ4 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: www.masterlock.com/business-use/locker-blockguard 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. Questions? Leave a comment below!
