one of those expensive super gamer switch keyboards.

A new Logitech wireless keyboard usually with a mouse, can be found on sale at places like Staples for 20 bucks or so, sometimes less. Keyboards are fairly standard, so you don't need the "recommended" one.

An often unmentioned advantage of a new one is the lack of dried coffee, cat hair, and breadcrumbs stuck under the keys .

On edit-- I now see you have a backlit one, and that changes things. I might still get the cheap backup keyboard, but it may be worth your while to take it apart and see of you can fix it.
