2010 F150 ~ We were able to successfully add a flip key FOB we bought on Ebay. It was frustrating as we got the same warning 4 times before the 1st key was accepted. We tried unsuccessfully 6 more times with the 2nd key (See image below). I contact seller and they are sending another blank flip key ...

I had the same symptoms/problem today, turns out the CH340 connector driver needed updating. Worked fine after update.
