When you say you took it apart to no luck, do you mean that you replaced the switch and it didn't work, or something else? I just replaced one key from the thumb cluster last night. It wasn't super easy, but the thumbs are on a regular pcb (which makes it easier) I wonder how hard it is to solder on the flexible pcb like the keywells are! I know you are prioritizing sea, but do you have any idea on cost to ship to the us? I might be up for a challenge
