The TPMS in my 2006 Lexus IS died 3 months ago after 15 years of service. The tire mechanic said it would cost $80 per tire to replace the sensors. I was so lucky to find these aftermarket units for less than $50 for a set of 4. They looked just as good as the Japanese-made OEM units, if not better (the OEM didn't have that waterproof seal). . My car needed a tire change, so I had the tire changer install these sensors during a tire change at no additional cost. Voila, no more signal light.
