  Un-screw all the screws on the external base.

  The panel then comes away quite easily.

  Now you will see inside your AN1X -there is a little
  PCB just of the long PCB with the keyboard contacts,
  undo the 4 screws for this PCB, but leave wires
  attached, unplug 3 wire cable labelled 'AFT'. Now you
  can access fully the keyboard PCB, carefully unplug
  the ribbon connector from the long keyboard PCB- you
  have to pull up the little locking pins on the side of
  the socket, don't just try and pull the ribbon cable
  straight out. Now undo all the screws for the keyboard
  contact PCB - there are alot.

  There is a plastic membrane which covers the rubber
  contact strip, key are underneath.

  It's all pretty obvious when you can see it all.

  I have checked the contacts and they look perfect.
