I recently got my first set of lockpicks and have been learning the basics on a few Masterlocks I have lying around. Tonight, I decided to pick my door, so I locked it and (with the door still open) went to work. It only took me a few minutes to pick it and I was pretty
Unfortunately, my lock has become stuck in the unlocked position:

I've tried to turn the lock from the inside (like I would normally do to lock it) and it won't budge much at all. I've tried sticking my key in there and it won't go more than a few centimeters. I can get my pick in there all the way, but I don't know what to do with it since it seems to me that all of the pins are set, upside down.
What can I do to fix this problem?
Thanks in advance for any help you can give.
