Today I went out to drive my 2013 to the market but my FOB would not unlock my door. I thought maybe my FOB battery was dead so I tried opening the door with the combo above the door. No luck there. I had to remove the lock cover and open it manually.I then tried to start it. No luck there. I tried to pop the trunk, no luck there. How do I access the battery? I couldn't unlock the back doors so I sent my 11 YO daughter to the back, pull the seats down, crawl to the trunk area and pull the trunk release handle (It was fortunate that, when I first bought the car and discovered the trunk release handle I would let her crawl back there and open the trunk as a game, so she knew exactly where it was). It would have been very difficult for me to make that crawl at my age and size. So, I figure "Horrible design" to not be able to access the trunk when the battery dies without crawling through a very tight space. I connected my jumper cables to my wife's car battery and then to my battery and before I could even start her car my horn started going off. I then started my car, disconnected the jumper cables, drove to the market and back and now all seems to be OK. So, what happened? How do I prevent this from happening again? Is this really the only way to access the battery when it is dead? Input welcome.
Thanks in advance.
