For ease of use, here is the programing document.
I did this on my Flex and it worked just fine. When I first questioned the dealer they did not know the procedure but I found this and told the dealer I was going to do it instead of taking it in and they said if I screwed it up they would be able to bring it back to normal. Took a lot less time to do it myself.
It worked just fine. The hardest part was finding the programming button, You have to take the cover off under the steering wheel to get at it.
Mustangs a manual so no remote start
