Lost keys on red keychain with USB drive

I lost my set of house and car keys yesterday around 3pm near Mission Plaza by Bubblegum Alley in San Luis Obispo. The ring holds a silver Yale house key and a spare car key on a bright red silicone keychain with a tiny black USB drive tucked in. A noticeable scratch runs along the brass edge, and there's a small faded 'Mom' charm on the ring. They're worn and important to me—the house key opens my apartment, and the spare key is my only backup. If you've seen them, please drop me a message; I'd be forever grateful.
