Off the wall TPMS question
Do the TPMS sensors in our cars emit an RF signal indefinitely when they are not "pressurized" (i.e., just sitting on the shelf)?
In other words, if I take them out of the stock wheels to transfer them to a new aftermarket set, do I have to do it within a certain amount of time (days, weeks?) before they need to be re-programmed by Lexus?

you dont need to do anything just take them out and slap then in those wheels. the pressure in the new tires/rims will "wake" them up. Just get a 2nd set off Ebay. They are ~110 for all 4 shipped to your door brand new. then all you have to do is toggle between the winter/summer rims!

I was planning on using the sensors in my stock OEM wheels (MAIN) to plug into my new aftermarket wheels, which won't go on until spring. My concern was, if I pop the sensors out of the stocks, put them on the shelf for a few months, then install them in the new rims in April will I have to get them reprogrammed by Lexus...
Sounds like you're telling me that as long as the battery is intact (8 year life span?), the sensors don't have to be "pressurized" to retain memory and should be recognized by the car in spring whether they're in a tire or in a box.

That's not what passnu2 said. He said you could move the sensors to another set of wheels without doing anything special. If you buy another set from eBay (or any other source), you'll need to have the dealer (or someone with a factory scan tool) program your car to recognize them.

no the sensors have a code embedded in their eprom memory. This code is programmed to your car. As long as your car reads that sensor code it will read its air pressure value. It will not erase from your cars memory unless someone overwrites or erases it.
You will only need to reprogram if in 10-12 years the battery runs out on the sensor.

OP...You have nothing to worry about by putting them on the summer set up before you use them They will be ready when spring comes around to put them on and toggle to sync them up!

Appreciate the enthusiasm, Mike . I'm pretty psyched about my new wheels and springs. Farmer's Almanac says we're in for a *****in' winter so add-ons won't see daylight until weather permits. Either way, my car probably won't hold a candle to some of the "Dream Machines" on this forum .

So just to clarify...
I can take the sensors from the factory wheels and place them on new wheels without having to go to the dealership to reprogram the codes correct?
Or...
I can buy a 2nd set of sensors and put them on my wheels but I will have to have it programmed at the dealership correct?
The flashing light is a buzz kill while I am driving!
Thanks for your help in advance
