Sequencer menu key

Sequencer menu key no longer works. Anybody know if this is fixable. I can’t open up menu or use any of the sequencers! Help!!

You tried blowing air behind it? Or taking the key off to clean it? Switch cleaner may help but keep the OP switched off during and for a while after using it. If all else fails replace the switch - where are you based?

I’m in the US. Trying to find a replacement keyboard. Ifixit are out of stock.

have you tried a factory reset?

had something similar happen with the < & > keys. the factory reset worked for me.
