Dash lights dead, no crank, no response from turning key.

Check the voltage or use a test light at the underhood connector, battery, emergency disconnect and breakout connection box in the trunk. Do head lights work? and stay on while trying to crank?

No I don't have a spare to swap out. I didn't realize it was the same switch across e53 and e46 otherwise I would have yanked it out of my old parts car just to have a spare.

-Yep-
As a bmw owner (older models) it's a must to collect parts that are highly prone for sudden failure.
