> You can copy the freaking key by removing the plastic of the yubikey4

Any more information available? googling for "yubikey 4 takeapart" got me nowhere.

The plastic dissolves in acetone, this is a neo not a 4: http://www.hexview.com/~scl/neo/

Found that link - though even after getting the Neo's circuit board exposed I didn't think it was as simple as "connecting the pins and reading the key out". Op also specifically says yubikey 4 :)
