Step 1: Understand What's Inside
inside there are four rotating plates with a notch the shackle to slide through. When you scramble the lock, the plates slide to block the shackle from coming out.
Step 2: Tension the Lock
I wrapped the lock around a chair (pictured) sliding the cables apart increases tension in the system. you need tension to press the teeth of the shackle against the lock discs. this lets you feel the shape of the discs better and decide when one of the teeth isn't pressed against steel disc and is just hanging out in open air.
Step 3: Rotate the Tumblers
Start with the tumblers that are hardest to rotate first. these have the most tension. tension makes the disc's shapes easier to determine. Now, there's a couple of things to look for.
Step 4: Have Nerves of Steel
When you get it, you'll be concentrating hard and i can guarantee the lock will fly apart. Its going to startle you. Don't make this remove the idea of setting the combo to something you'll remember from your head.
