My tire store installed new tire sensors, but couldn't reprogram the TPMS. Said i needed to go to dealer. My dealer couldn't figure out how to relearn my TPMS. They charged me $75 to tell me I needed to have another $300 part installed, "that may not fix the problem". Well I just bought my own DRB III emulator ($170) and did the work myself. No $300 part needed! Apparently, my dealer didn't know how to perform a relearn of the TPMS, as shown in this video.
