How to remove macbook pro 2016 butterfly enter-key. CHECK DESCRIPTION for instructions!
First pop up the whole left side of the key, starting from the top left corner, then lift the left side up so that the key forms a 45 degree angle with the surface of the keyboard and finally pull the key to the direction the left side is now pointing to (45 deg angle). You may have to jiggle it a bit to get the hooks/hinges loose. In the "video" you can see that the c-clips are on the left side and the "hinge"/hooks are on the right when the key is attached normally to the device.
Be careful and you'll be fine!
P.S. First time I took it off, I took a guess and unluckily popped the right hand side first so I broke and bent some clips, but it works almost normally now that I bent the clips back to their original form.
