One key is not working anymore
The calculater works fine except the key for "3" doesn't do anything.
Is it easy to fix this?
I cannot seem to get it open.
Ist dies eine gute Frage?

The calculators have plastic snaps that firmly hold it together. It takes some determination and spudgers (or screwdrivers) to take apart.
Once inside you can take out the circuit board and clean the button side with isopropyl alcohol. You can also clean the rubber membrane while you're at it.

Oh. If you can't get it open (i dont have a texas instuments calculator), there's not much you can do. I can't think of what you can do. Im sorry.
