KN650 BROKEN KEYS

Hi i have 2 broken Keys E-B. I think the same E broken

And Keys F-A F " "

I actually need 1 spare of each in case it ever happens again.The Keys got broken when someone moved it and just ripped the cover off which had got caught in the E & pulled it straight off the keyboard inc.Spring The F is broken on the side but can still be used I do not want to replace the keyboard as it has only been used in my home studio maybe 60 times in total and is still as new. I would also like instructions of how to repair it if possible I am a competent person that should be able to replace..The big problem is i live in Gran Canaria & they are useless here i hope someone will be able to help me source them
