How do not use the key to open the three-ring padlock
Two hair a clip you know? That can be removed above the wire, take it down. Unlock to be patient and turn gently
Find a master of the lock on the line, he will give you open.
You can use a more solid but not too thick paper clip a self-made unlock tool!
Shape like a three-dimensional [H], or [L] is also OK!
Put it into the lock inside the most, and then slowly pick out, along the inside of the ball sliding (with strong jitter), back and forth many times sliding, and finally feel all the ball in place, you can screw to the lock The direction of the twist!
I used this method to open the "han" lock, but not very skilled. Landlord himself was slowly looking for a trick.
