Lost & found keys & keyrings in Oneonta

Found keys on blue lanyard near Oneonta library

I found a set of keys this morning around 7:45am in the parking lot behind the Oneonta Public Library on Main Street. There are three keys on a frayed blue nylon lanyard, plus a small round metal tag engraved 'AR-23' and a tiny red heart-shaped keychain. One key is a brass house key with a distinctive old notch, another is a silver key with a triangular bow, and there's a compact black car key fob with a few scratches. The set looks a bit worn but functional, and the lanyard is starting to fray. I know how stressful it is to lose something like this, and I’d really like to reunite them with their owner. If these are yours, share the initials on the metal tag and a quick description of the keys so we can verify and arrange pickup here in Oneonta.
