I have checked the battery voltage, and it is right around 12.63. I am an ASC Master Certified Auto Tech, however I do not specialize in Fords and therefore I am asking for help with specific nitty gritty Ford problems. Every vehicle has its own nitty-gritty specifics. I specialize only in European, Audi Volkswagen. I have also replaced the batteries me fobs and it did the same thing. If I am sitting in the car the fobs work perfectly well and all functions work well. As soon as I step out of the vehicle, I have no signal reception. I am wondering if the GEM , which is part of the fuse block in the kick panel of the driver's side, needs to be replaced totally or if there is an antenna wire that has broken or gone bad, I don't know?? I have read other articles saying that I just need to unplug all three of the connectors that plug into it and clean them out and replug them in. Perhaps that will work, however based on my experience as a technician it seems that there is a problem with the GEM itself. I'm just not experienced on Ford products, and just need some input if anyone has any similar experiences of this happening. Let me know!
