Found keys with red panda keychain near library

I found these keys this afternoon around 3pm in the parking lot behind the Chico Public Library on Main Street. There's a standard house key, a silver car key, and a red panda keychain that makes the set easy to spot. The car key looks worn, and the house key has a blue tag with initials 'KB'. The owner is probably nearby, and I'd love to get them back to whoever lost them. If you're missing them, tell me the last place you used them and describe any distinctive features.
