Here is a demonstration of how to open a padlock in 1 minute or less using nothing more than scissors and a coke can.

On similar notes, here’s a demo on how to minimize potential combination sequences from 46.000 to 100.
That was an awesome demonstration of how to actually pick a combo lock Hrafn. Though I must say I think I’d be too impatient to do it and probably end up breaking out a can and making a shim. :-)

Haha. Yeah.
I guess all we need now is a video on how to get away with murder and we’re all set to become super-villains *grin*
[...] Just like the How to Pick a Padlock, this method of using a coin operated washing machine for free is so simple it makes you wonder how they would ever collect any money in these machines! [...]
Interesting… takes some practice to get it right. I asked a friend of mine who works at Master Lock about it, he said that by summer of 2009 their style of these combo locks will have an internal device to prevent this, so pick ‘em while you can!
um, yeah.
the “no real security” statement is a joke, right?
For starters, that might work on the lock in the video, but it won’t work on my masterlock, I just tried it and it will chew up your pop-can shim just like his chewed up the “commercial” shim.
Second, when the lock is on a hasp or otherwise used to secure something, you don’t always have room to screw with it the way you do when it is loose and in your hand.
Third, why not cut the chain or tear the hasp off the door/whatever? A bolt cutter is quick and easy and will work purely by giving you enough leverage to pry open a cheap lock, you don’t need to cut anything.
No lock is impervious, they just keep things closed against casual fiddling. One can usually find a way around a padlock easier than trying to open the lock itself.
