I need to replace a broken key, is it difficult?

[Gaston]

I can't speak for the Kronos, yet, but have replaced keys several times on Yamaha series synths.

Replacing the key is usually the easy bit. The hardest part is usually the disassembly to get to the keybed.

In general, if you can take things apart and get them back together without having too many bits or screws left over then you can replace a key on a keyboard.

My guide for the key repair on the mighty SY99 is given below to give you a general idea of what might be involved (with the disclaimer that the Kronos could be completely different! ).

Thank you for the tips and yes you're exactly right. I got to the point of having to remove the keybed and it seemed out of my experience. Fortunately there's a proficient Korg technician nearby who's gonna replace it for me next week. I definitely feel better about it. I'll let you know how it comes out and thanks again for the suggestions.

Hello,

Remove all screws under the Kronos

Remove the stripes that relies the keybed on the electronic boards

Take care about metallic grey pieces, it's sharp !

Put the keybed upside down, pull the key that is broken slightly, it will move about 1 or 2 millimeters, it will click.

Remove it from the keybed, by taking care of the fixations. Replace it and make it click by pushing on it forward.

Rewire the stripes and close the bottom panel, done !

Perfect Niarf! I'm printing this and will do this... Thank you so much for sharing...

Interesting idea. So like I could tune they B key to C pitch, then tune the Bb key to play the B pitch, then the A key to play Bb...

Yes, you could.
but I wouldn't recommend doing so many changes to a scale all at once it's really like using a capo on a guitar strings
too many capos would extremely limit you -- you then would have to play all the songs tranpose to the same rootkey

then take it the whole way down the keybed? Cool idea! I'll call it jazz! LOL

It doesn't have to be the whole keybed, just an adjacent note where the 'broken key' is..
If you alter the whole keybed things would get real messy..but,..like i said the suggestion was only a temporary workaround.

Pro-tip: At least on the Kronos 61, you don't need to take anything apart to replace a key. Just press down (reasonably hard) at the end of the key closest to the pivot point to push the spring down and slide it forward and out. Installation the new key is just the reverse. If it's a black key, you need to remove the two surrounding white keys first.

I'm certain that this will not be applicable to the Kronos 73 or 88, but I've replaced numerous scratched keys on my Kronos 61 using this method.

Zombie thread alert!

I've followed the above instructions and managed to remove the broken key. However, I'm not sure how to replace it using these instructions, because the spring stands too high for the key to clear it. How do you keep the spring held down so that the key can go over it (clear it)? Thanks!

Well, that was easy enough....For anyone who's interested or may come across this thread later, the answer is that I used a thin metal piece (anything would work, really....even an unwound paper clip) to hold down the spring long enough to get it underneath the key. Then I slid the key into place.

Glad you were able to get it to work.

Hi SeedyLee, removing the key was a breeze as you said but do you have any tips on reattaching the key to the spring without taking out the keybed?
Thanks!

Depends which Kronos model you have.

Depends which Kronos model you have.

Sorry, should've specified that I have the 61 key 1st generation version.
