Korg Nautilus 88 Key Replacement

I have a the Nautilus 88 and 3 keys are broken. I see the parts here on Syntaur.
I was able to remove the keybed to work on it.
However, it’s not clear to me how to replace a key.
Does anyone have experience or a instructions how to replace a key?

Hi: Take a pair of needle nose plyers to take the old key out squeeze the end that goes in the metal brace.It will pop out or break .Thats ok its junk.
The new one goes in on an angle.The new key has a notch on each side and the spring goes into the key.Go in on an angle till it pops in,That’s it.
