In order to learn the unique IDs of the new TPMS sensors you need to interface with the vehicle using a Chrysler diagnostic readout box (DRB) III scan tool and a Crossfire/Sprinter multiplexer cable or have a DRB III emulator and multiplexer cable. The tool itself was quite expensive; an emulator (connected to a PC) is less expensive but still quite pricey for something you may only use a few times. If you want to continue with a working TPMS system, you either need to find an individual with this tool (there are a few), or find a dealer with access to the tool and Sprinter/Crossfire cable. Many Chrysler dealerships got rid of their Crossfire-specific tools years ago so they may not be able to do the work. For dealerships that do have the multiplexer cable laying around, they will typically want to charge you an hour's labor for a job that takes less than 10 minutes. All they will do is place a magnet on each valve stem, one at a time as requested by the tool, to activate the sensor which will transmit its ID. The ID is then memorized by the Crossfire's computer. I had this done a few years ago when getting new tires and replacing sensors (they batteries last around ten years or so). I made an appointment and showed up at dealership, then had to wait a couple hours while they sent a courier out to borrow the multiplexer cable from another Chrysler dealership. Even with just a half hour labor plus a few ridiculous add on costs for things like "digital storage" I was around $90 IIRC.
