Anyone find a set of keys around Myrtle Avenue between Kent and Steuben?

Lost them yesterday late afternoon, somewhere between where I parked on Taaffe near DeKalb, to the post office at Kent & Myrtle, to another couple of stops on Myrtle ending at Bergen Bagels, where I realized they were not in my pocket (I still bought an everything, ha).

Fortunately, I still had the car keys, so I went home and got the spare pair from a neighbor, but this set had an extra key I need. 

Please PM if you have info. Thanks!
