I did use the search option on here but could not find any info. I have a 09 F150 with the factory installed remote start. I had bought a new 2011 F150 key/fob. It has the four buttons with the remotoe start button built built into the key. My dealer got everything working with the new key but the remote start. Service guy told me the 09 remote start are not compatiable with the 11 key/fob. Has anyone done this upgrade?? I know I had seen this somewhere on the internet but now cant find it. If so how do I upgrade to this key setup. Thanks!!
