Hope someone can help with this issue. Drove to the store, everything was working normally. I tried to unlock the car with my key fob when I came out of the store and the car would not unlock. Then tried opening manually with the key and the alarm went off and could not shut off. I tried starting the car and did not start. I tried with second key fob and the same problem. Now, every time I open the door the security alarm is set off. Batteries in the FOB's are fine. I Heard it could be a dead battery causing the problems, checked that, fully charged. Car is still unresponsive to FOBs, alarm sets off every time I unlock it manually, and still won't turn over! Not sure what the issue is so if someone can advise that would be great.
