Keys on blue lanyard with house and car keys

I lost my keys yesterday around 3pm outside the Tower Bridge in Old Sacramento along Front Street. It's a standard silver keyring with four keys: two house keys (one Schlage, one Kwikset), a Toyota car key with a black plastic fob, and a tiny picture-frame keychain showing a calico cat. The lanyard is blue fabric and a bit frayed at the end, and there’s a small dent on one key's bow—easy to spot if you find it. They’re really important to me; they unlock my apartment, my car, and a lot of daily life. If you picked them up, I’d really appreciate returning them.
