So Im driving on the road, out of nowhere my car shuts off! Tried steering off into a neighborhood, my car continues to turn on and off. I took my keys out and now they are in my hands. But my car seems to be trying to turn on. I see the starter belt moving and my engine is shaking, trying to turn on. Wtf.
I took it to an auto shop and they're charging me $700 to fix it. Said it was the ignition switch.
​​​​​​ Took it home, replaced the switch, now car wont even turn on. It seems to start but won't fully run. Its starts and the keys turn but it wont fully turn on.
Do i need to program my keys? I have only one key and its the original. Help what do i do!!
