Sometimes it is useful to lock the keyboard. If you want to clean it fast with a brush, but you don't want to disconnect it. I know it is possible to lock Windows but if you press space bar and some character's you'll start typing your password

It shouldn't be a default feature. I understand someone could lock the keyboard by mistake and it wouldn't know how to unlock it but, it should be an custom option in case you need it

You can add up to three additional layers, one of which could be completely empty.

I know that, but if you are cleaning the keyboard just by pressing the swap layer key, you will unblock the keyboard

How would a lock key work then? You press the lock key and then you have to replug the board to unlock it again⁉️

Something like this is feasible if you waste a full layer with no keys set

But what it appears you want is something like this:

This requires firmware development

I would just disconnect the USB cable when cleaning...
