2022 Model X Key Fob has a different technology from the older ones. Therefore, if you have a fob from an older model, it will not pair to a 2022 Model X. I just bought a new one, and tried for an hour to get a key fob from my 2019 to work. I finally called service and they said that the 2022 Model X requires a new fob. If anyone reading this is interested in buying my old ones, they are for sale. If ur interested please let me know.
