Will I have to pay a fee to get my iPhone 5 lock button fixed?

My one year warranty ends in November but I have a little crack in between my flash and camera. It's right where my mic is but honesty it doesn't really affect anything on my phone. My main concern is my lock button. If I can't get a completely new product like some of my friends have gotten, can I just pay for the lock button portion? It said that it could repair that specific piece possibly. If so, how much is it usually?

Is my iphone covered under warranty?

So I just got my iPhone 5s this Sunday. And I made an appointment to the Genius Bar today. I had a question about a vibrating noise under the camera. And the Genius Bar guy told me he was going to open it up and see if there was going to be anything wrong with it. He comes out 15 minutes later and says that there's nothing wrong with my 5s. So I go home and later I find that there's a lot of debris under the front screen. My question is, will this be covered by the warranty? Do I tell Genius Bar that it was one of there employes fault? And do I get a new one or refurbished?
