Let me first state by saying that I am not in the locksmith profession, nor do I have a desire to learn about picking locks (although from what I've read and researched on the Net, it would be a fascinating hobby). What I can tell you is that I need help or your advice in getting into my shed which is secured by a tubular lock.
Long story short, I coach my son's baseball team and was rushing to get all the baseball gear loaded into our SUV for practice. I needed an item from my shed for a drill that I was going to have the kids do. Needless to say, I lost the keys to the lock after getting the item from my shed. For the life of me, I can't remember where I placed them. I've traced back everything that I had done that evening, but have come to a dead end in my search....ugh!! As such, I've written the keys off as lost and have ordered a new lock set as a replacement. Here's my dilemma...what is the most inexpensive way to remove the old tubular lock? As it is right now, my kids are bikeless and pretty soon ghosts of baseball players from the past will start appearing on my lawn as it is starting to look like a scene from the movie "Field of Dreams". My neighbors think that I've boycotted the gas industry because I haven't cut my grass in the past week.

Anyhow, here were my options for "breaking" into my shed:
1) Call a professional locksmith to pick the lock;
2) Purchase a tubular lock pick and try to DIY; or
3) Perhaps use a drill to drill out the lock pins (is this doable using a regular drill bit made for metal).
Again, I'm trying to do this the most inexpensive way, if possible, since the lock is basically history without the keys. Here are pictures of the lock and the structure it is used on to secure the contents. I believe it's a seven pin tubular lock. I can't saw it off because it sits flush with the door.
