For regular users with a consumer laptop, a damaged key or keyboard means:
Laptop defunct. Use an external keyboard if not affordable.
Used my X220 for ten years, handled it with care, but after ten years a new keyboard was a nice uplift. You can also switch languages but especially also the layout between ANSI- and ISO.
Buying an Apple device with ANSI in Europe? Pain. ThinkPads? Buy anything. 30 EUR and new keyboard.
Er, exactly! Most people replace the entire machine within that time, so they still don’t need a replaceable keyboard. You’re now arguing with yourself.
