From what I read on the internet somewhere is that the steering wheel no longer locks, but the reason behind the change was interesting. It seems that there was/is goverment regulations that say all automobiles sold in the US must have some form of security or theft prevention. The locking steering wheel became the industry standard years ago to meet this requirement. However, now that the Jeep keys all are computer chipped as to being able to start your vehicle, this has become the new form of fulfilling the goverment theft prevention requirement. So the locking steering wheel is no more.
So for the auto manufacture it is a Win-Win situation. They save money from less spent materials to lock the steering wheel. And stand to make a small fortune in selling replacement keys to owners who loose, misplace keys and have to have the keys/vehicle reprogrammed.
