I found some Mercedes car key/remote opener thing. it has a little pocket knife attached to it. I found it by the parking lot on Madison and 50th ave.

I also found a Toyota remote opener thing. with no key just the remote. I found this one by the Sahara tent.

I feel bad for the people who lost these because... well loosing anything, specially your keys, really sucks..
If they belong to you let me know. We can work out some thing to have them shipped to you.
