I have ridden the following tutorials.
http://home.howstuffworks.com/lock-picking.htm
http://www.lysator.liu.se/mit-guide/mit-guide.html
Is there more tutorials that would help me with those keys & locks?
The main question still is, where to get a nice set for picking those kind of locks.
Thanks alot!
