Keys on red heart fob with two brass keys

I lost my keys yesterday around 3pm near the Jackson Public Library on West Capitol Street, in the parking lot behind the building. It's a small set on a black leather keychain with a red heart-shaped fob; there are two brass keys—one stamped Kwikset and the other Schlage—plus a silver car key. One of the keys has a tiny dent near the teeth, and the red heart fob is a bit faded but still legible. These keys open my apartment and a family heirloom lock, so they have sentimental value and I really need them back. If you've seen them, email me at [email protected] and we can arrange a quick pickup near the library.
