You've seen plenty of videos about hacking Master Lock combinations. But what about those American Locks? They always seem to be forgotten, since Master Lock is the biggest combination lock producer out there.
To get the American Lock combination hack, you needn't pull up on the shackle like other combo locks. Nor do you need to use an aluminum can shim. All you need is a dull knife and a couple flathead screwdrivers (a small one and another really small one). You'll crack the code by opening up the back of this cheap lock.
