I own a Monte Carlo ss 2006, and while driving the battery cable or another part of it came loose or malfunctioned, to where it was short circuiting the power to the car. I was on the highway driving and lost all power, even the alternator stopped. This seemed like it was triggering the theft protection; anyhow I had no power, and had to coast to the side of the road. I put the car in park and couldn't turn my key back to the release position, so I popped the hood but couldn't get out of the car because the door wouldn't unlock. I pulled on both handles and with no power the car wouldn't let me out. A person stopped and opened the hood and moved the battery wiring around some, which gave me power to at least open my door now. I took the car directly to the dealer ship to be serviced and looked into. My main concern is if I am in a wreck and lose all power to the vehicle then how am I to open the door(s). The handle should unlock the car door from the inside with or without power.
