if i have the key in the ignition and open the door, the chime dings like normal, but when i take the key out with the door open it dings really fast and does not stop until the door is shut. what could be wrong? i have had it open with the key out and it will ramdomly stop dinging then start again, cant figure it out. might be related but when i put it into programing mode to try to program the keyfob i got to work on the car, it flashes a error code.
