When I’m driving down the road my car won’t shut off. I have to pull over to the side of the road turn my key completely off and take it out put it back in and start it. It takes a couple of times to get it started as I have to move the key back and forth and then it will start. I did a check engine light check. And it is saying something about a Anti-Theft ignition problem. My headlights stay on all the time and blink when it is shut off.
