How do I replace a faulty key

Basically they all snap off Prying from the left or top works best. There are small pins (hinges) that keep the tops in, and most hook over a keyboard tang at the bottoms. Shift, space bar and some other keys have springs and/or wire legs to keep them aligned. ’’’ Breaking off the pins will destroy the key.’’’ Single replacement keys can be had at e-bay. Good Luck, N.
