Pulling my Toad for the First Time!! Couple of questions

Regarding the statement

"When you tow, the key must be in the ignition. It would be very easy for someone to steal the car while we are parked and getting lunch at a restaurant."

I have a dummy key with no chip in the key. The car will not crank with this key. To crank the car, I hold the chipped key against the "no chip" key, and it will crank for the warm up routine. I tow with the "no chip" key in the ignition and the doors locked.
