Found keys with blue lanyard near Walmart, Dodge City

I found a set of keys this morning around 10:15am in the parking lot behind the Walmart Supercenter on Wyatt Earp Blvd in Dodge City, Southwest Kansas. On the ring there are two brass house keys and a silver Ford car key fob with a small dent on the corner; everything's a bit worn but functional. A red plastic tag reads 'MEL' and there's also a faded blue USB tag attached, so the set is easy to spot if you know what to look for. They’re in decent shape overall, and I’d really like to get them back to their owner—if these sound like yours, we can meet up in the Walmart lot or by the Dodge City Public Library to swap.
