I found a set of keys last night at the bike rack outside 401 N Michigan. I was the last bike there other wise, I would have left a note. It had two separate Krytonite locks on it, along with a yellow mini flashlight.

Let me know if they're yours. I'm posting on Craigslist too, and I'm also contacting Kryptonite to see if they can help match the number on the back of the lock.
