Starting Problem 2011 E550 Cabriolet

[Will P]

Drove my 2011 550E to get a new tire installed. Service Tech came back and told me the car will not start?
Put the key in, all the PRE START functions happen as normal. (seat belt adjust, steering wheel adjust, etc, etc...)
Turn the key, nothing happens? No sound, no clicking, no starter engagement, starter never turns. Absolutely nothing, silence?

This happened 23 Aug 2025. Car hasn't started since.

Has anyone ever experienced this?

Per forum rules, it has ZERO to do with the focus of this forum, which is the W124 chassis V-8 models.

Have you tried multiple keys?

Yes. My key and my wife's key. Same result.

What fault codes are present?

Not sure? Where would I Find Them? Nothing displays on the dash board.

OBD codes from a diagnostic scanner / tool.
