>>334523First off go buy yourself this.
http://www.budk.com/product/Secure-Pro-Credit-Card-Lock-Pick-Set/158911.utsThey're six bucks and on Friday you can get two sets for the price of one. Plus you get a guide books and they fit nicely in your wallet for EDC. They're aluminum so just be gentle when picking.
I would first go ahead and look up the MIT Lockpicking Guide. Read it and study the mechanics behind picking. Also go onto youtube and look at as many vids as possible, preferably ones with cut away locks.
Go and buy yourself a couple different locks from Walmart and get practicing. If you have any difficulty google that lock and determine if it has Security Pins. These pins just make it a little bit more difficult to get in.
If noise isn't a factor for your b&e look into a pick gun like the one I've attached. These things open doors pretty fast but they do have the drawback of noise.
A third option are the use of bump keys. VERY noisy so research them before thinking of implementing them. You can get a set of them for sixty bucks.
Now this part is important. If for any reason you feel like you are about to get caught you need to get rid of your tools. Trespassing is a ticket in most cases. Getting caught with burglary tools is a felony and will get you a ticket to meet Bubba.
I've been in more buildings then you guys can possibly imagine and have never gotten caught. Why? Because I practice until I get everything down perfect.
If you folks have any questions about Urban Exploring or getting inside please let me know. I'll be monitoring this thread.
