Download MIT's Ultimate Lock Picking Bible (FREE)
"Looking for a good source of information on how to pick a lock?
Someone has anonymously posted the classic text from MIT (Massachusetts Institute of Technology) on how to pick any lock in the online Zine Library. (Sort of constitutes as a zine, right? Pamphlet maybe?) The text is free to download as an e-zine in PDF format."
The MIT Guide to Picking Locks is THE bible. Completely necessary in every lock-smith-crook's library.
