Answering my own post for the answer. I finally opened it up after my post.
You have to remove the small rubber pads with a sharp knife to revel the 6 screws underneath.
Then you will have access to the keyboard and the PCB (held together with a ribbon cable and a ground wire):
The keyboard itself cannot be easily repaired. The metal plate is held by plastic pins that were cut off then melted to that the metal plate is attached firmly with the keys.
The membrane layer is between the metal frame and the keys. If we remove the plastic pins to access the membrane, it will no longer possible to reassemble the keyboard again.
I will stop here in my quest to repair my 2030. It's been a pleasure to use, however I will look for something else as replacement as the company seems to be dying unfortunately.
