Bezel (nut) around ignition stuck. Fault indicated after trying to break out.

What is your question?

Trying to remove dash panels to get to headlight wire. Procedure showed removing ignition trim and nut. Nut was stuck, so damaged when trying to remove. Gives ignition fault now. If I order new switch, what happens with keys? Do I have to get them recoded by the dealer to work on new ignotion switch?
