Oh! Now seeing your post on the forum here, I think I better understand your PM now.

When you said to me that you had trouble "getting it open" I thought you meant the kwik pick, not the lock. I presume now that you have the pick in fine order, you just don't know how to use it.
Here's the bottom line. If you bought this tool just so you could open one lock and save a call to a locksmith, you probably have wasted your $20. Lockpicking is a skill that takes time to develop. Maybe you'll be lucky and get the lock fairly quickly. Maybe not. For starters, try reading the MIT Guide (all 50 pages) and read the lockpicking article on howstuffworks.com. If this all seems like too much trouble, then I'd say call the locksmith.
If you have a genuine interest in learning lockpicking because you think it will be a fun hobby, read the above. If not, you are really just wasting your time. It's not as easy as just stabbing the lock with the pick and hoping it pops open on you.
I'm sure this is not the answer you were hoping for, but I hope it helps anyway.
