[Fulltiming]

Thanks everyone for all the suggestions. Got up early this cool fall morning and drug out my folding ladder. I went window to window as I thought I remembered after the door handle broke earlier this year that I was going to leave a window unlocked so that didn't happen again. Although I had tried to push each window open from the ground, on the ladder I found the window I had left unlocked. The only thing worse than being stupid is doubting that you did something right!! I pushed the window open and crawled in. Glad it was a large window. I was able to easily open the deadbolt from the inside and remove the screws so I could remove it. You were right, the tongue, or as one parts photo I saw called it, the 'driver bar' had come out of the cylinder and looks like it may have sheared off the end that held it in the cylinder. I will be contacting some locksmiths later today to see if anyone can replace the part.

Again, thanks to all of you for your thoughts and suggestions.
