My [XXX] was sleeping in the parked car. My wife was also in the car with her. Engine and AC were on. The key was inside. Doors and trunk were unlocked. I got outside the car and got my older kid. The doors opened as usual. Then my wife stepped outside the car to get something from the trunk, and she closed her door as well to avoid heat coming in. The vehicle immediately auto locked the doors with the key inside it. So my little one got locked inside. The doors or the trunk did not open again. There was no cell reception, so no way to get roadside help or call 911. The car was parked under direct sun in hot weather. It then shut off the engine (and AC) as well. To avoid heat stroke, we broke into the car to save the child. Obviously damaged the vehicle in the process. The problem of doors/trunk locking with the key inside happened a second time the next day. This time engine was off. I was already inside. My door was open.
