    Thanks for the info man. You know I may try this scissor jack method one day. I know once you break the bead and push the sidewall down, it is very easy to remove the sensor assembly.

    As for you question, the batteries inside are not rechargeable. By recharging, what I really meant was to shock the battery so it can work briefly for my scan tool to read it. Technically any type of dry cell can be charged a bit. But it won't be a long-term solution. Dry cells won't keep charge. It worked in my case because these sensors require a very little power to function. The cell in it was showing below 3 volts if I am not mistaken. I hooked it up to my RC charger and applied around 4-5 volts for about 10 seconds. It was more than enough to bring it back to life. It has been over a week and the sensor is still functional. But if I put it back to wheel, it will fail within days or maybe hours because it will keep transmitting when the car is in use. That little amount of juice I put in will be gone in no time.

    They make rechargeable type of coin cells, but dry cells are definitely best for this application. They last for years. You will not have this car most likely when the next battery replacement is around :)

    How about airing up the tire afterwards; did that go easy? Details?

    Do you mean to pump up the tires? I have a plug-in-the-cigarette-lighter portable air pump. When I tried it the first time, it could not do it. The bead was just not seated tightly enough so all the air leaked out. Then I removed the valve stem, and it worked. The tire needs around 15 PSI to push the bead to seat in the rim groove.

    I guess if you use a more powerful pump, you don't need to remove the valve.

    If you get a small amount of the tire bead lube the shops use that'd probably help too.

    I sprayed some soap water. I guess the bead lube probably works better.

    If it helps any my first "bad" sensor would stop being bad for months. (Car was rarely driven). So when I had practice I prepared a new sensor as soon as one acted up, then replaced it second sign of trouble. (This was for my wife's daily drive)...

    REVVL V+ 5G ?

    Hello @iskoos and everyone else. I was searching the forum for a solution to my TPMS problem (2010 Prius) and found your post. My problem is exactly the same! Here is your quote from post #12:
    ...The shop replaces that sensor and writes its ID onto vehicle module properly but at the same time another sensor losing its bind with the TPMS module...
    What was the solution? Grateful for any help!

    Shop incorrectly paired the wrong ID into the ECU. @iskoos purchased a TPMS tool, read the IDs, and correctly registered the correct ID.
