Proceed at your own risk
Having worked on many laptop keyboards over the years, I was interested in how both the keys were attached and how the coating/paint was applied.
If you are used to Macbook Air style switched (Friction captured on one side, slid on the other) then you will know how to work with these.
The paint is layered: Clear plastic > white coat > black coat.
This was wet sanded with 2000, 2500, 3000 wet/dry silicon carbide cloth.
Keys are dished so the top is a pain (paint is super on there so kudos Framework)
As for removal (I have seen around the forum it said that individual keys are not replaceable so again, proceed at your own risk) I made a quick gif of me removing and attaching the cap.
The “north” (towards screen) side clicks up, then you slide south to release the bottom. To re-attach, sit the key in, angle slide south, then push down lightly at the north side (you will feel the click)
With the keyboard launches, I may or may not just wait for the blank white keys (I need more expansion cards anyways )
