Can I easily replace keys in the new 2016 MacBook Pro?
I just removed two keys on mine: can't believe there's no good info out there on this yet. The clips are on all four corners of the key, but you should only pry the top edge of the key as the clips on the bottom are designed to slide off toward the bottom, rather than pull straight up. I used a thin piece of plastic (the plastic-only edge of a laminated tag) to pry the top edge. A credit card would probably work but might be a little stiff for the initial pry.

Once you have the top clips off slide the key down until the bottom clips are off as well. It's a nice flat surface underneath, I had no qualms about cleaning with a damp cloth. To replace the key slide the bottom clips on in an upward direction, then press the top clips into place once the key is centered in place.
