Hi, I’ve got one of these keyboard - I’m a fan of it in general. It’s pretty high mileage, and they don’t make em anymore. Nothing is obviously physically damaged; my “U” key and a handful of keys on the number pad are just dead. Anyone have any thoughts on fix? is there such a thing as a diagnostic app for Apple keyboards? Thanks!
Es esta una buena pregunta?

All the switches are on one flexible print, it is not possible to change individual keys, unfortunately.
In my case the spacebar is not working anymore, I removed the key cap and there are 3 individual switches, but non is responding, hence the decoder must be the issue…

Unfortunately there is just no way to repair these with the exception of replacing the keys.

Is replacing the keys possible?
What does that mean? It's like you are saying there is no way to fix it with the exception of fixing it.
It means that, with the exception of replacing keys, there are no other repairs that can be made.
I suppose you mean the key-caps. The key switches are on a single printed circuit board.
I believe that what mayer is saying is it is possible replace the plastic part of the keys, that is the piece we can see and move with fingers. Those mechanical parts can be replaced but that will not restore function to dead keys. When keys are dead, the breakdown is inside the keyboard, in parts that can't be seen without breaking the board apart. The failed element is contained a thin layers of plastic that have connectors on them, sort of a circuit board. There are multiple layers of plastic. Each key has a small section of the layered sheets that send signals when pressed by the eys
What Mayer is saying is no one has found a way to repair damage to the layered sheets.
The video at this link shows the plastice layers and how they fail

Lost for lost... I immersed the keyboard in an ultrasonic bath. Then I dried the keyboard on a slightly warm radiator. Three days. The dead keys are resuscitated… I did the same thing with a mouse… I risked nothing more! The keyboard was broken…! …

That's just to open and inspect; no reference to testing or fixing keys that aren't working. Actually, it looks like it's taken from this site:

I tried repairing a Apple keyboard and couldn't actually get the keyboard apart,without destroying it.Other keyboards should be repairable.
