I think most "tire shops" do not know that the Crossfire system is somewhat unique. OEM (Schrader) or compatible (mine, NAPA, are compatible, found on chart on our Forum) must be "paired" to car's receiver using dealer tools/process; talked about here hundreds of times.
Not difficult, once installed.
180 & Reliable Ron present perhaps a better new solution: Schrader 33500 sensors, (but) are cloned to each original type sensor actually being replaced, with special tool, as I understand it. If you no longer have originals, you may have to go OEM route & use dealer for "pairing" to your car, assuming receiver is ok. Hope this is correct & helps.
