Drove my 2014 jeep cherokee limited to work today and when I was heading home and tried auto start it would not start. I got close to the car and the dashboard was flashing. I trying to open the door but it could not detect the key fob in my back pocket. I had to push the unlock on fob to open then door and I tried stepping on breaks and push start but nothing. No lights on dashboard. It would flicker and turn completely off. Had a buddy with a battery charger come help.but that didnt work at all. After a couple of more tries the keyfob stopped working. Could not lock or unlock doors. Had to manually lock doors. No more lights, seem to be dead now.. Car would not crank or do anything. Do I have a problem with my battery? Please help.
