Veh:  2000 Grand Am 3.4

The other day after coming out of the grocery
store my can wouldn't start and I determined
that it was because passlock for whatever reason
thought the car was being hotwired and cut
fuel.  The security light wouldn't go out.
The owners man for the car makes it
sound as though you've got to keep the keys
in the ignition and in the "on" position for 10
minutes for the light to go out.  Because of
this I turned off the lights and radio etc.

Could I have turned the ig to the "off" position and/or
removed the keys and gone back inside the store
and let it reset or does it require the keys in
the "on" pos to reset?

I'd just like to know this incase this happens
again.

Thanks
