1999 Chevrolet Silverado 1500 LT 3dr Extended Cab 4WD SB
With the doors locked and the windows up if you lose the battery contact on either side negative or positive you are locked in. If someone tries the door handle to free you it will not work. I was lucky the window down at the bank drive thru and had to use the key on the outside of the door to unlock. Something GM didn't tell the 99 silverado owners. Also, the stock battery bolts are to short for a good bite into the threads on the battery. I replaced both with longer thread bolts. A friend of mine put in a sliding rear window for a exit just in case. Checked with local dealer and of course the answer was "I ain't heard of that before".
