Lost keys on silver keyring with dachshund charm

I lost my keys yesterday around 3pm near the Fort Gratiot Lighthouse at Lighthouse Park in Port Huron. It's a brushed silver keyring with four keys, plus a bright red silicone tag and a tiny orange enamel dachshund charm. One key is a brass skeleton key from an old apartment, and another is a modern car key with a red fob. The whole thing is a little scuffed from daily use, and it has sentimental value because it's my everyday set, and I really need it back for work and rides.
