I have a 2010 MBP that's still under applecare (until June 2013) and I've been having problems with my keyboard. For starters, my left shift key and space bar are severely warn out. They stick heavily and sometimes do not register since their springs are pretty warn out. Does anyone have experience with bringing their MBP into the Genius Bar for a similar problem with their keyboard? How is it handled? Is it replaced easily or do they give you a hard time since it's a keyboard? Do they replace just the key or do they replace the entire keyboard? Note: It never got wet, and the MBP is treated with the best care. Thanks!
