I have a auto start i purchased from a shop that is no longer around, i went in on a Saturday, the unit i had was not working, and had been told by another shop it had been set on a different mode some how accidently and needed to be switched back, the safe and sound guy smiled when i told him, he changed the batteries in the unit that starts the auto start, and it worked just fine...super Guy, super price, took 10 min. pete/BSJ Knives of Alaska
