With most of my sensors being 8 years old, I bought a new one just in the case that I needed a new one. My car passed inspection a few weeks ago, but 2 of my tires were cracking, good tread, but cracking. When the new tires were mounted, I had the sensor available to the mechanic, but He told me my existing ones were still good. I now have an extra TPMS sensor I will not use this year; please tell me, will this one last 5 years or so without being used?
Thanks for the response
