If you have tried both Reset procedures & no change then it is probably a fault with the switch.

A DIY task you for you?

Switches should be readily available from Electronics Store or Keyboard Repairers

Otherwise trash it and buy a new model as a Service Tech will charge more than then keyboard is worth.
