Lost house keys with a blue keyring and a small toy keychain near Devon Tower in Oklahoma City.

I lost my keys on the 15th of October around the Devon Tower area while I was walking my dog. They are on a blue keyring and have a couple of house keys along with a small toy keychain attached. I retraced my steps several times but couldn't find them. If you happen to find them, I would really appreciate your help in getting them back!
