Autostart works only when the key is in the car

Question

I installed EVO fort4 kit in my 2012 Ford Fusion. I used my two factory keys and programed them per the instructions. The auto-start worked for about two months. Now it will only start when I have the key inside the car ( it does not need to be in the ignition)  The key works to unlock and lock the car normal. Can you tell me what I need to do to get it working again?
