Lost keys on red lanyard with panda charm

I lost my keys yesterday around 4pm near the Safeway on Main Street in Sterling, Eastern Colorado. They're on a bright red nylon lanyard with a black car key fob and two metal house keys, one of which has a dent in the head. The set also has a tiny panda charm and a blue sticker with the initials 'PP' on one of the keys. The lanyard is a bit frayed from rain, and the panda charm is my favorite, so I'm really hoping someone picked them up. If found, reach out to me at the email below; they have sentimental value and I really need them back.
