You just need to find/buy a new key (Ebay, Yamaha). Take out the keybed (a few screws) and put the new key on, it's really quite simple (done it to lots of old synths and there's barely anything inside an AN1x to remove).
I don't recall seeing 2nd hand keys for AN1X on ebay often so google for them and ask Yamaha. Everything is fixable. :)

Maaan, i just mangled a key. i accidentally dropped a hard acrylic sphere on my synth and it shattered a key into various shards. Can most music shops repair something like this? or have i inevitably screwed the pooch?
