theres also the fact that we have no idea who you are, we have no proof you own this lock and by the sounds of it, you need in quickly, the best option is to call a locksmith.
if you're just learning to pick, read the MIT guide, read the FAQ's and stickies and search for homemade picks or mc guyver picks to find things to use to pick, or just buy a real set. then get yourself a lock like a kwikset, its cheap, reasonably easy to pick, can be taken apart to aid learning and possibly the two most important factors, its not relied on for anything (since locks picked a lot tend to get destroyed, especially when you start out) and it belongs to you. if we were to explain how to pick a lock and you broke into oyur neighbours house, we'd be in trouble, so legal right to pick is important!
if you're getting into picking, welcome to the forums, have fun and good luck!
if you're just looking for a cheap way in, im sorry, you're probably out of luck, for one thing picking isnt easy, it takes a
lot of practise! the best thing to do is call a locky.
hopefully i've added something useful and helped you a bit Bahamut
