random dead keyes but no information online on how to open and replace keybed

A quick Google confirms no manuals available for this.

I think you’ll have to trailblazer this one!

Check the keyboard contacts to ensure no water damage first.

Which keys are affected?

I also searched high and low with no results, but i will say Syntaur does sell new keybeds.

Hope this helps!
