Red lanyard keys with bicycle charm

I lost my keys yesterday around 3pm near the Belgrade Theatre on Belgrade Square in Coventry. It's a small set: two metal house keys and a car key on a bright red fabric lanyard, with a tiny silver bicycle charm and a blue plastic USB key attached. The car key has a black plastic head, and one house key shows a little dent on the tip. They were in my pocket as I was heading toward the city centre after leaving the cafe outside the Belgrade; I’d be really grateful to get them back since they unlock my flat and my car.
