For those seeking the answer:
1) Call your shop with your key card handy and give them your electrical number and mechanical number.
2) With #1 they sell you an ridiculously over-priced blank key ($27.5)
3) With #3 and your current key, you bring that to a hardware store and they cut the blank
4) With #4 in hand, you go back to the Ducati shop with proof that you own the bike, AND your red key. They then program the key to work with your ecu
$50 later, you have a spare key.
