Yea I think that may be the next step, buying new key fobs.If the dealer was willing to give you new batteries perhaps they would be willing to give you new key fobs to see if that works

There is a module called the radio control Module (I believe) it is located on the right pillar beside the second row headrest. Or at least that's where they used to place it. That module controls the key fobs, ford pass connect and the am/fm I believe. But I don't know much else about it.On my jeep wrangler there were issues with the WCM (wireless control module) and it would do stuff like this. I don't know how ford does it though.
I am not 100% certain what the fix was. In my case the jeeps have a key ignition and supposedly there was static electricity from the key that did something to disrupt the system. I don't know for sure if the wcm was toast and had to be replaced or if there was some other fix for it. My problem came and went but after taking it in whatever they did resolved it. In the jeep's case it ended up being a warranty item and when I took it in I was getting some other safety recalls done and didn't pay much attention to what the paper work said when I was done.Did you end up having to replace the WCM? Or what was your fix? Thanks
Robert thank you for the response! If this is problem, then what would the solution be? I’m not sure if this is the issue because we have a security system at out residence. Sometimes the vehicle recognizes the fob at home, sometimes it doesn’t.Does the vehicle start when you place the key/fob in the recess under the cup holder when the vehicle isn't otherwise responding to the fob? If it does, that eliminates the fobs themselves as the problem. The random aspect sounds like an interference/hacking issue. This was mentioned in one of the posts above. The system is designed to shut off access to the fobs when the receiver in the vehicle is being bombarded by "false" signals of the same frequency. In their infinite wisdom, our FCC assigned the fob frequency to wireless security systems used in homes and businesses as well key fobs. If your vehicle is parked in the vicinity of one of these security systems, it can lead to a shutdown. Hackers trying to get into random or specific vehicles in parking lots can accomplish the same thing by constantly running random codes at higher than allowed power output, trying to pop locks and start cars.
I experienced this along with 3 other vehicles parked at a South Dakota grocery store a few years ago. All 3 vehicles shut down the RF controls. They were parked between a remote parking lot camera and the base transceiver for a half hour. We experimented parking a vehicle in the same area at another time and repeated the issue.
Let us know what you find!

Thank you for taking the time to respond. This all helps tremendously!
