    Both he and Discount Tire did show me front driver's side had low battery so I am sure it is coming soon but had it died after I got the passenger's side replaced, shouldn't the TPMS light been flashing for a minute like it did before to indicate a bad sensor? Instead he returned it to me with a solid light without asking his peers or double checking on top of the now silly request for me to press the tire pressure button and drive around for a bit...seems like pretty poor customer service :confused:

    The batteries can go bad in less than a couple years. The drag is you have to pay to have the tire demounted then reinstalled & balanced

    For sure, though that wasn't the issue of the thread. I know the front two sensors were the original ones we got from the first owner about 10 years ago so they have definitely served their time, so I have no problem in paying what I need to in order to replace them...returning the car to me with basically a "new" warning light (brought in with blinking 1 min tire pressure light and given back to me with solid tire pressure light) was the frustration here...either way, glad it is fixed and my wife won't complain for a while.

    FWIW, Discount Tire is not bad. I'm sad they refused to replace for you. What I've seen:
    1) Anybody can go to their tire pressure stand (typically outside and/or one of the service doors) and get pressure corrected AND get TPMS reprogrammed, takes seconds, no charge.
    2) If you purchase your own TPMS and ask nicely, they will install for the cost of a dismount/remount. $10 total. (Yes, if a totally different configuration you would want a rebalance as well.)

    I'm not frustrated with Discount Tire, they have patched many tires for free over the years. Maybe I could've gone back with the new TPMS that the other shop installed but as for #2, at least from my encounter, even if I had brought my own sensor, Discount Tire rep said they absolutely would not work on that wheel since the tire I mounted was too old even though treads are totally fine..

    You only have to break the bead on the side where the monitor is.
    You replace it, the put air back in it. It will usually seal easily since it had already
    been seated and in that position for a while.
    So no need to balance the tire. Other than the new monitor could be a different weight.
    Likely not enough to effect the balance. And if you get lifetime balance and rotation,
    it won't cost you anything.

    Here's something interesting. Last fall, I bought new rims, winter tires and TPMS sensors for the then new to me Prius Prime 2017 and had them installed at a shop. Then last spring, when I've put the summer wheels back myself, I left the winter wheels stacked in the garage. The TPMS light stayed off for several days, until I went for a drive over 50 km away from home and it stayed lit until I got back home three days later, where it turned off during the next local drive. At first, I didn't make the connection and thought one tire was low. It's only after the third time that it did that that I made the connection that it was still reading the TPMS of the wheels stacked in the garage! So I brought the car back to the dealer for them to reprogram the car for the TPMS in the summer wheels. The TPMS light stayed off after that. I used the Carista app to get the Sensor ID of the winter wheels before they were reprogrammed at the dealer and used it again to get the Sensor ID of the summer wheels. I swapped them back last week and used the Carista app (subscribed for a month is still cheaper than the dealer) to reprogram them myself.

    I'm surprised that after several weeks of them being stacked in the garage that the car was still communicating with them. Like you, I was expecting them to go in sleep mode when not spining.

    PS, sorry for the wall of text lol.

    The TPMS system can request a transmission.
