Well, I'll try my best to answer your question.. First off, it's a fairly good set, from what I can tell, but its not really the tools that are going to get you anywhere. I'm an amateur with picking locks, but I've learned that most of the time, it can be done with two small paperclips, bent into a straight piece of metal. The main thing you have to remember, using a tool-kit or not, you have to concentrate, and try not to let anything else bother you at the time, you have to block out everything :
