Good Morning, I parked on a military base next to a building and left my phone in the car. When I came out the key FOB would not unlock the car. I had changed the battery in the fob a week earlier, so I know that wasn't the problem. I pulled the battery out and put it back in. It finally opened the door, but would not start the car. I used my phone to start the car. When I got to the build where i normally work, my FOB was working like it is supposed to. Could there be an RF signal around the building where I had the problem that is blocking my FOB signal? Anyone else have this problem?
