Tpms 315 mhz
So, I'm curious what variances TPMS sensors have from manufacturer to manufacturer (infiniti, dodge, etc.)? I understand there are different frequencies, believe the infiniti is 315MHZ, but what keeps a certain 315mhz sensor from working with another 315mhz car?

There's handshaking and authentication keys involved. I'm sure it's more complicated than this, but that's the general idea.
On a previous bike, it had a sort of smart key system. No fob, no start. On more than one occasion, when filling up at mobil stations that supported speedpass, I had difficulty if the bike was too close to the pump. Had to roll it back or forward away from the antenna, then it would recognize the fob - google KIPASS if you want more info.

If you have the tpms sensors on your car's existing wheels then you can copy the sensor ids to new set of TPSMs - need to have TPMS id reader/copy programming tool. Once ids have been transferred then the wheels with new sensors will work fine- that's what the tire shops do.
