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 ---

Why not just see if you can return it ? The place you bought it from might have the answer as to how long it will last unused. ---

I’d like to do this, but the kid in me ruined all of the packaging, I didn’t pay much for it. ---

Oh I see, using it turns it on. Thank so much for your help Insightful. ---

We had this discussion a couple weeks ago and could have saved you some money. ---

They may be still working today but what about next year? It won’t save you money having the tires broken down later to replace the sensors when they fail.
