If you're looking to use the car display you either need to use the OEM sensors or find a sensor that will work in the same frequency.But they won't work with the internal TPMS display on the car.
Also those look like typical internal sensors - but they just have their own external display
So I had a sensor fail, looked everywhere and went with the Schrader 3033 who are the same manufacturer as the original ones. I was having the warning about TPMS problems for two weeks or so before replacing the sensor.You're looking for RDKS Schrader OEM 3033 e.g. this one, or an equivalent. There was some discussion about this in another thread but I can't find it. Here's an Amazon link - might not be the cheapest around...
