I locked the doors with the window open, and after fifteen minutes I came back. I stuck my hand through the window to unlock the car by pulling the small latch, my factory alarm triggered and my horn was beeping for two minutes. Then while it was beeping I tried to start the car. It didn't start. There is a small LED light by the driver door where it signifies that your car is armed, now this light doesn't come on anymore either. I can't start my car as well. Could my starter possibly be dead???
