No I leave the key in the ignition. With the oem theft deterrent set to level 5 it cuts power to the fuel pump until you disarm it with the keyfob. The car will crank and drive for about 30 seconds before the fuel runs out. I found this out the hard way when I drove it off the dealer lot and it shut off 500 feet away.

I feel bad for the sales lady who came to help me I cursed a great deal.
