Black keyring with brass house key and dragon charm

I lost my keys yesterday around 3pm outside the downtown Missoula Starbucks on Main Street. The ring is a heavy black metal with a brass Schlage house key and a worn Toyota car key. On the ring there's a tiny red enamel dragon charm and a bright green plastic tag that says Gigi in white letters. The house key looks a bit bent and the ring has a few scratches from daily use, plus a slim silver key with a dented head that sticks out. This set has sentimental value—the house key opens my late grandmother's home—and I'm really hoping to get them back.
