I went out tonight and locked my car and turned on the anti theft alarm system. When i came back the door key would not open the door. It did however open the trunk. I then climbed in the trunk and into the car. When I stuck the key in the ignition the alarm went on. I was not able to open any of the doors from the inside or turn on the car because the alarm was going off. Other than taking the car to the dealership what can i do? Ho do i turn off the anti theft system off whithout using the key in the lock from the outside?
