My alarm will go off while I am driving causing my steering to lock. I will have to get out of my car and unlock the passenger side door to get my car to start. It will still be able to play the radio but it will not let the engine start. It does it in the middle of the road and is very scary. I am afraid to drive my car because I don't know when it will happen. I just replaced the battery and altenator so I know it's not do to that. I would like to know how to stop this from happening any more even if it's getting rid of the alarm system.
