Ok, I had a" J" that the cap kept coming off! I bought a replacement key from
Here it came with 3 parts the J cap the Hinge connector and the rubber rebound piece. There instruction on changing out a key could be better. However I was able to change this key out in about 5 minutes or less. So repairing keys on these G series NB is possible, the only way they won't work is if the metal tabs that hold the hinge in place are broken off and missing. I had to adjust one of these tabs to get a better grip on the hinge. I have magnifying goggles so I was able to do this easily.
Thought I would pass this information on as I remember in the past there didn't seem to be any way to fix a bad key except to RMA to the service center.
BTW to remove a key cap pop up the top edge then the bottom edge will come unhooked.
