I posted about this on TRS but though maybe another set of eyes might help. Everything was working fine, 5 minutes later I went out to the truck and couln't unlock the doors with the transmitter. They work by the door switches but not the transmitter. The next day I went out to the truck and they suddenly worked fine! I hadn't touched anything. Now, once in a while when I go to start the truck, it won't start and the PATS light flashes. If I keep trying it, evenually it will start. I have replaced the batteries in both transmitters, checked the fuse and tried my spare key. I can't find the RKE module. It is suppossed to be in the passenger kick panel but I don't see it. I'm at a loss at this point. The truck is a 2007 XLT 4x4 with a 4.0L SOHC. Any help would be really appreciated!!!
