I have watched a dealer mechanic friend of mine do it one time on mine when I had to replace one of the TPMS sensors.
He walked up to each wheel with some kind of hand held scanner to get the pin or some kind of reference number off each one of the TPMS sensors.
He then used a Chrysler DRBIII tool to program the new number in probably the body module. Not sure which module stores the numbers.
He only had to change one as all the others was working ok, but he checked them all just to be sure while he was going through the process.
When I purchased the new TPMS sensor, the instructions that came with it said that once you drove the vehicle around for a few miles with the new sensor in place, the OBC would pick up the signal on it's own, but this never did happen. Drove the thing around for over a week and it never did pick it up. So I went and talked to my dealer mechanic friend and he fixed it in a about five minutes....didn't cost me anything. Nice to have friends in certain places.
