Spacebar, arrow down, backspace - beyond repair?

I’ve gotten a magic keyboard (A1644) from my nephew. After years of abuse the spacebar and arrow down and backspace stopped working. I don’t know if liquid was ever spilled on it - but it isn’t sticky at least.

I have removed the spacebar for good measure and just pressing down on the soft round with my finger does nothing.

Is there any other types of tests I can do to make sure it’s broken beyond repair?

The rubber cup has a conductive area on the other side which shorts across the two contacts (switch) If its not working that’s likely the end of the keyboard.

That's very helpful. I'd bet that's the case. Then I won't have to bother checking the other keys as it will be a waste of time! Thanks for that!
