It is our preconceived notion that locks on the door is wisdom but after watching this video locking system becomes ridiculous and our faith shatters, because you can unlock any kind of lock before saying jack Robinson
Cheap combination padlocks can be unlocked easily by using a thin metal piece slid between the body and shackle. These thin pieces of metal are commonly known as padlock shims. Padlock shims are made of very thin spring steel, and they come in 3 or 4 sizes to fit the contour of the hasp of the lock. Just push one down between the hasp and the body of the lock and twist to disengage the the locking mechanism and Voila! It's that easy to open an inexpensive padlock.
There are several methods such as lock bumping, lock picking and a kit that applies wise mechanism to also open dimple locks that have a serious profile. The clever thing about this tool is that the 'U shaped foil tube' is wrapped around some sort of needle, and the foil can not be pushed in when getting into the lock! Once the key is inserted, the needle is taken out from the back of the tool, and the pins are now resting on the foil.
All kits and techniques fall flat when you see how easily a lock can be unlocked easily, fast and reliably.
