Watched their official video about it and carefully removed the key. The problem came when I wanted to put it back and the suuuuuper thin (half a mm or so) clip the keycap uses to atach to the mechanism snapped off.

Haha, same here with an ultra fragile piece of plastic that snaps as soon as you touch it. Except mine was a connector socket soldered to the motherboard and they made zero effort to help me get it fixed.
