This isn't as simple as "no immobilizer". My 2004 Ford F250 doesn't have one either. Thieves got into it and tried extremely hard to force the ignition and steal it. They tried hammering a flat head into it and rotating. Didn't work. They tried grabbing the outside of the mechanism with some kind of pliers and rotate, and that didn't work. I can see they easily spent several minutes on the whole ordeal, and didn't get anywhere. The entire lock mechanism was destroyed, almost shaved smaller from how many times they tried and their pliers slipped. When I got to it a few days later, I had to get home using that truck. I put the key in the ignition and turned it, and drove off.
