Pretty much what the question says, the key itself works, but the key (in my case, it’s the “W”) is now dislodged, and can’t attach itself again. On further inspection, I realized that 1st, the “W” key itself had 2 broken hooks (bottom left and bottom right) out of the 4 on each corner (a replacement key is easy to find) and, the bottom left cap of the butterfly mechanism is broken too, so I’m looking for a guide that would ideally help me replace both, the butterfly mechanism, and the key itself. For more info check the image I attached. the red ring is the broken cap from the butterfly mechanism

Thank you very much for the help!

You’ll need to get a new set of parts. Here’s a source for the needed parts 2016 MacBook Pro Retina > Type-M
