I had a new key made for my car today.

I took it out and put the Business CD unit back in so they coulld make the changes. Not a big deal since I can swap it out in minutes. It appears that the factory radio is part of the onboard computer system, and it affects all of this, including coding for the factory anti theft system. So if the coding is done, the Dynavin can be reinstalled and all will be good. So when you take your factory radio out, hang onto it in case you need to have this service done.
