I went to the store and locked the Jeep. When I came out and grabbed the door handle it opened as usual. When I got in the car, the car shut down in about 5 seconds. It's been doing that ever since the first time the dash lit up like a Christmas tree. The dealer reported it to Jeep but they changed the pcm and said not to worry about it. All I had to do was step on the brake and everything would come back on. Today when I stepped on the brake it said No Key Fob. I hit the start button which set off the alarm, horn, lights going crazy.
I pressed the unlock button on the not present fob. The alarm shut down, but the screen still said no fob. I stepped on the brake, hit the start button and the car started.
