On my 2006 I have one TPMS that is going bad and I intend to replace all of them. My question is if I buy the TPMS sensors from CULTRAG Performance (formally GM parts house) and have them installed at the local tire shop, do I have to take the car to the dealer to have them calibrated to the car???
Easy to do yourself with this tool from Amazon. I use it every time I put snow tires on. Directions are in the owners manual. The tire place will probably do it for you if you take the car too.
Any decent tire shop will have the device to reset the sensors. I had new tires installed this morning and they reset them for free. If your tire shop is installing them then the reset should be included. It takes less than 2 minutes.
Is there a date code on them, or some way to tell when they were made? The spare I have sitting in my trunk does not seem to be dated.
They will last longer if not being driven, but not forever- the batteries will eventually die on their own, and anyway the unit still transmits occasionally (1/hr?) when sitting on the shelf.

I am only guessing but is it possible they are shipped with a little plastic piece obstructing the circuit which needs to be pulled out before installation like some electronic items that you buy?

That would be nice, but the one I bought as a spare just came in the little GM plastic bag, nothing to "activate".
OTOH, the decay rate of the battery even when it's not being used at all, might not be much better than the quick "once per hour" blip that it currently does just sitting on the shelf.
Of course, some of them die rather quickly in use and others seem to go almost forever.
