I don't know, since it is the only synth I have completely disassembled
before. I have heard that you can clean the contacts however - that might fix
your problem. Once you get all the screws out, you lift the keyboard up and
disconnect the ribbon connector from the bottom, flip the keyboard over and try
not to destroy the motherboard in the process, use a Phillips to unscrew all the
screws on the velocity sensor pc board, then use a flathead to pop all the long
metal pins that brace it in loose from the aluminum frame that holds the keys.
The circuit board has lots of little rubber thingys that the keys hit, they
lift up and there are metal contacts under them. What chemicals to use to clean
them safely, I don't know.

I have at least 3 keys that don't work on one of my K3's and so I mainly
use it as a midi module.

keyboard. It would take about 1 hour, no soldering involved, just lots
of screws and funny pins.
