Okay. Going to go to autozone after having my jumped to see if it is an old battery. Car is 5 years old and I think it has been orginal. Last few nights have gone down to low thirties with lots of dew.

The dead battery is most likely the problem altogether! That should take care of the alarm as well.

I am hoping. That is an easy fix and not as expensive as if I had to take it to the Hyndau dealer. They would rake me over the coals. I thank you for helping me.
