At the community events we where told that the keypad is a glued part for technical necessity.
Now seeing chens tear down photo linked above might suggest otherwise since all the parts are disassembled.
Only if you look closer at the white lower keypad part it is kind of bend after the tear down?

I was under the impression it is not user replaceable until i saw the tear down. Clarification would be awesome. Is it only replaceable if you match chens skills, which is highly unlikely and thus they better not advertise?
