Hi I have a 2017 grand sport LT1. It's been about 6 months since I took it off the road for winter. I tried to start it today but the battery was low. It wouldn't turn over. Than the battery completely died and locked me inside (for a second) until I pulled the release next to the driver's side seat. I closed the door and it locked me out. I can't get into the car now. the key fobs don't open the doors or the truck. It's like the car is on lock down. Are there any tricks to opening the car? Do I need new batteries in my key fobs? Nothing is working. Literally.
