My battery went dead a few days ago, since the alternator is dead, and i am not driving the car. before the battery went kaput, the alarm went off and the whole thing double locked, and then it was dead!!!
I did not get rid of the keyhole, so I was able to open the driver's door, and pop the passenger door but not the rear doors. I pulled on the emegency trunk release, popped the top gate and pulled the battery to get recharged outside the vehicle.
I think, these cars are designed to lock everything up before the battery's last breath... Are they? And this can happen on a long term airport parking, not a good thing..
