Set of house keys on red leather keychain

I lost my keys yesterday around 3pm in the parking lot behind the Safeway on North State Street in Ukiah, Mendocino County. It's a standard brass house key and a Ford car key on a worn red leather keychain that has a small compass charm attached and a faint bite mark on the plastic fob. The keychain is about 4 inches long, with edges starting to fray from daily use. This set has sentimental value, it's the keyring my grandmother gave me, and I really need to get it back.
