I was leaving from class today and I got to my car, and the doors would not unlock. When I press down the button on my fob, the LED in the fob lights up as it should, and the car's turn signals (front and back) flash as they should, but the car won't unlock. I tried turning the key to both positions (Horizontal and vertical) but nothing worked. Any recommendations will help a lot! Luckily my friend was there to drive me home, but my car is sitting all alone in the parking lot!
