My car was vandalized and my car stereo was ripped out and ever since when i go to start my car i get a security light flashing and i have to put my key in the on position and wait about 10 minutes for the security light to stop flashing. When i took my car to the insurance company to fix the window i told them about the problem they said they would check it. When i received the car back they said there were no problems with the security system but this problem still exists. What could be causing this problem
