I don't know about the Chevy. I have had 5 Toads, 2 Fords, a Camry, a Saturn, and now a Honda. I just turned the key far enough to unlock the wheel, never had to disconect the battery or pull fuse. I did run the battery down once in the Honda, I left the Roadmaster brake system pluged in, while the van was parked for a week.
