Answer to "Can the keyboard be replaced?"Keyboards can be removed in many of the Pro units. 2009-2012 units have about 50-ish screws that hold it to the Upper case. It can be replaced. that being said the upper case it actually the bottom of the laptop. Apple laptops are running upside down all the time. So the keyboard, or the upper case are the last parts to take apart. You will need to remove nearly every part of the laptop to change the keyboard. It can be done though.
