My key isn’t “stuck” in the ignition. The key won’t turn to start the car. I am not 100% sure whether the “Stickey key” is the same problem as I am having, @Wadsworth My mechanic does high end foreign cars but mine is the only Crossfire @bluecoupe . The instructions I printed out actually have the Mercedes part number listed. Mercedes estimated the part would be available sometime Jan 2020.
@Wadsworth the eBay link was very useful. I emailed it to my mechanic. We’re meeting on Monday to put together our fix plans. I am willing to purchase the parts on eBay in a nanosecond. My hunch is that the computer will have to be reprogrammed, correct?
We (mechanic and I) have not found anyone that has (?? Star 3/4 program training to reprogram). You’re spot on Scott, I am stressed. Took it to Mercedes dealer thinking maybe that was s good option but the appointment didn’t go so well. Instead of considering the car as a Mercedes they look at it as a Chrysler and want me to take it there. If Chrysler can replace a signal bulb that’s burnt out and says I need to buy a complete headlight assembly for 1 small bulb, I am not sure I want them touching my baby! I couldn’t even get the paint code from Chrysler (smh).
The guy that I am working with has done all the maintenance on my vehicle. This is the first major issue I have had on my 19 yr old car. No one here seems to to have seen the problem before - even though apparently it was an issue with both Mercedes and Crossfire vehicles. Everyone is skittish which doesn’t inspire confidence.
I wish I knew a local Crossfire mechanic that could do this but sadly I haven’t found one.

@Wadsworth how would I know if the SKREEN unit has a problem? I am guessing it’s just the ignition tumblr but I am no mechanic... Is there a test we can do on the vehicle that would show some kind of code?

Thanks for all the support, I am grateful!
