1) We’ve driven and enjoyed the tires for a couple of weeks; however, the TPMS sensor light is still on. I know that it’s normally supposed to reset when it detects the new sensors. I stopped by the tire place and they told me they I had to go to the dealer to get the sensors to initialize. Is that true?
2) If it is true, should I pay for them to do it or wait until I get new tires (and sensors) for the front? I had a mechanic friend tell me that they should all be replaced at once. Note that the TPMS was working fine before I had the rear tires replaced.
Thanks!

How/why did they replace them (?), Did they provide them and say they would work (resetting after some time (
WRONG!), did you provide the sensors to them and they said they would work, or did you say put them in and they will work? Like the previous posts,
they have to be reset to the specific car/system they are installed (to the correct car system using the CORRECT sensors/transmitters). If the light is still on, either the wrong sensors were installed, one or more sensors were not calibrated, or one or more sensors have a low battery (the front?). Too many questions to answer given your situation.
