I bought a MBP late last year and the R key on my keyboard keeps popping up. It doesn't completely pop off but the right side snaps up and I have to press and click it back into place. It's been doing it for a while now and so I figure a small piece of plastic under it has broken or something along those lines. What are my options with regards to repair? I didn't take out Apple Care or anything like that. Am I SOL?
