I didn't look too much before posting (maybe others have done this? LOL) and there has been a discussion on this TPMS. For this I apologize. Still the video may be interesting. Here is the new Schrader TPMS reader/programmer in action. The sensors are about $50 each on Amazon. Unfortunately the programmer/reader is about $250. Still may be worthwhile to find a shop with one can can read/program for you. Could be a good way to go for those of us doing seasonal tire changes.
