When the apple store replaces a battery in a 13in retina MacBook Pro, do they replace the top case and keyboard/trackpad assembly too? I ask because I have a key missing and my keyboard and would like them both fixed at the same time.
Did you bring it into a Apple store? If you did and asked I'm sure they would do it. If you sent it in, they don't have to do it, but maybe if you get a lucky the technician will do it.
