I have a 2011 Journey and today when I got out of my vehicle and pushed the button on the driver handle to lock the vehicle, it did not respond. I tried using my FOB and it did not respond. I then opened the door and used the power door lock and it locked the doors. I went on to do my errand and then when I came back, I tried opening the door by the door handle and it didn't respond. I tried my key FOB and it didn't respond. I used the emergency key to unlock it and then when I opened the door the alarm went off and I could not start the vehicle. The message said "Key Not Detected". I thought maybe it was the battery in the FOB, although I have not seen a low battery message. I went into the store and bought a new battery, still didn't work. I had to get my vehicle towed to the dealership. Any ideas what the cause may be?
