Cinch pins or locks?

When we had a Chevy Malibu as a toad we used an unchipped key for towing and knew that no one could start the car and drive off. So we used hitch pins without locks. With our new CR-V we need to used a chipped key in order to comply with the directions for towing, so now we use locks.

We have an unchipped key (half the price of a chipped key - really the same key, but they don't program the car for it). We use the chipped key to go through the drill to ready the transmission, then turn off engine, put it in park, pull the chipped key, insert the unchipped key and turn it to the towing position - then lock the doors with the chipped key.
