[@fett327]

For those of you wondering why anyone would go thru the hassle of changing the battery... the problem is with some makes/models (Toyota in particular), buying new means having to reprogram the new TPMS codes to the car computer. They wont just relearn the new ones. You cant do the programming without specialized tools, thus costing you money buying them or paying someone to do it. THATs why changing the battery on the existing sensor is useful for some.

[@JohnSmith-pk4xy]

Yes thats the biggest problem that'll cost $300 or more just to change them at the dealer. Money grab.

I just bought four new sensors off Ebay, not the first time I've done it with other cars. $21 including shipping/tax for all four. Bought a "relearn" tool for $8. This battery replacement thing is a waste of time, an absolute waste of time. Installed the new sensors, put the 2015 Chevy Equinox into learn mode, started at the left front and took all of about a minute. WHY would you be going to a shop for all this. Where I live, shops charge 20-25 bucks for a mount and balance. It should n't cost any more than that to put the new sensor in.

[@johnstefanick5216]

This helped me a ton! Thank You. Let me suggest using a box cutter ONLY to lift the battery tab enough to clamp on the tail with needle nose pliers. Clamp on this and twist slowly, you will gain about 1/16", do it again. Now the tab is free from the battery. The back side is a little difficult, but it works there too. I got 5 TPMS sensors cleaned like new and battery out in less than an hour.

I don't know what the costs are in other parts of the country, but Discount Tire charges $70 each or $280 for four of them. This procedure is great if you want to go through all of this. And how long will this last? - maybe for years I suppose but I bought an Autel TPMS tool and program new sensors. Its easy and is a long term professional repair. I've done several sets of these and my friends give me a few bucks to do it and the tool is paid for. The Autel MX sensors are $30 each or less. Or you can buy pre-programmed sensors and the tool will program them to your vehicle.

Checked with a tire shop. The estimate was $40 (sensor) + $20 (programming) +$25 ( mounting etc) per tire. All tires need new sensors calling for $$$$.

[@jimpie231]

Replace sensors when you replace tires. I lost a sensor at 9 years, tires were almost replaceable. Next year I replaced tires and sensors. I did this at Discount tire, they wanted $50 for each sensor. I bought my own and they didn’t charge me for anything but the tires. However, get a quote from them. My car is a 2009 Honda Crv, 5 years later and TMPS is still working and I’m going to be changing tires, but I won’t replace sensors till they start getting closer to 10 years old. I bought the sensors on ebay, $44 for 4. Do not buy used or refurbished, newest sensors are rubber stems, older are mostly metal, like shown in this video. Once you’ve research this, you’ll understand the differences. Dealers charge way too much for this service. PS: I bought a new set of rims and tires on line (better price, special tires), had them installed at Discount tire, they charged me $20 per tire. That was $80 for installation (including balancing), installing my TMPS sensors (which I bought on line), and programming them. They had a little bit of problem programming these (2020 Subaru WRX), because it was so new, but they did it. It took an extra 10 minutes, but they didn’t give up. The system worked perfectly.

I did a battery replacement on one TPMS sensor for my 2007 Lexus ES350. All four wheels had REDI-sensor VDO SE10002A model sensors. It all went well but after driving 800 miles nothing changed and my orange TPMS warning light remained. I was able to take it to Pep Boys and asked a mechanic to try and "trigger" the failed sensor by holding it up his expensive Ateq VT56 scanner ($850) to the sidewall adjacent to the valve stem.. It took what seemed like a long time (20 seconds} but his Ateq VT56 scanner finally triggered the repaired sensor to turn on, according to his scanner. My light stayed on until I drove 1 mile away from the shop and I guess the signal was detected by my Lexus and turned off! When I got home, I used my XTOOL D8BT to analyze all the sensors and the repaired sensor was now reading correct psi, temperature, ID number, and battery status where it had failed for the one month since I installed the new battery. So my advice is to understand that there are a lot of similar sounding terms out there in these videos. I think words like trigger and activation are the same, but learn, re-learn, and reset are not the same as triggered which is what the owners manual for the REDI-sensor stated what must be done when new. Because the voltage on the bad sensor was reading only 2.8V (battery says 3V) and was probably much lower this past winter during 11 deg F temps, I believe my sensor turned off completely and needed to be "triggered". My XTOOL D8BT could not do that. Only a TPMS designated scan tool worked. I also believe that the Redi-sensor TPMS sensors on my Lexus are not OEM and installed before I bought the car in 2022.

[@Btu555]

just curious, the light was on when you bought the car because they didn't do the relearn so even replacing the battery the light is still on?

Many confusion descriptions for term of reset, trigger, programming, learn and relearn, activation etc. just fool of us. But seems no one truly understands how system works.

It's easier to leave the "check tire" light on because to have a safe car, one must check the tire pressures every couple of months as temperature due to weather changes will always release some tire pressure due to heat transfer effects of contracting/expanding rims.

Regarding the soldering operation: The cleverness of buying a tabbed battery to avoid the problems of trying to solder to the incompatible surface of a normal battery is great. Still, soldering the underside is particularly awkward, it appears. Has anyone tried to solder the tabs to the circuit board instead of soldering the existing tabs dewelded from the dead battery to the tabs on the new battery? This would require more silicone excavation, of course, but seems like a robust solution.

Don't ask your tire guy to help you with any of this! The insurance company would have kittens if they found out.

Any trip to the emergency room will wipe out any savings, so be sure you understand what is happening when you break the bead.

They refunded the money. All the other places I checked had 20 week leadway etc. I ordered plane non tab batteries and will spot weld my own tabs. UPDATE: 4 months and all are working great. One tip I have, that makes soldering easier. I bent the bottom battery tab and bottom tab from sensor up so they both were pointed straight up. Placed a small piece of material between the battery tab and the battery. Done so the tab would not short out the battery. Made soldering much easier and the silicone covered it all up.

Maybe some precision resistors might boost my confidence.

Is need to reprogramming after battery change?

[@erwinmelgar9575]

I suggest keeping your hands away feom the direction of the cutter. It's just a matter of time dor you.

I was quoted $100 each to have them replaced by the company where I buy tires. You can buy new sensors of course and install them but since they will have new IDs you have to reprogram the computer to recognize those new IDs. And that takes another piece of equipment that costs. And the new sensors might weigh differently from the old ones. Replacing the batteries avoids the need to reprogram and it keeps the weight nearly identical. Here's a question my engineering mind has. Each of those sensors has a unique ID so the computer knows which is which. That way it can show you the pressure on, say, your passenger front tire on the little display. But what happens when you rotate your tires? That passenger front might go to the passenger rear or driver rear. How does the computer know which position on the car a given sensor ID is at? Do they have to reprogram the computer when your tires are rotated? Actually tell the computer that the ID that was on passenger front is now on driver rear?

Great question! Anyone?

Nice video. Definitely going to just buy a new tpms sensor instead of going through all that lol.

[@tnonesoung]

If you buy new sensor you’ll have to get it relearn

[@FaithMerry-m3x]

On a challenge level 1 to 10 for beginner soldering what level is this,

[@robertoguerra5375]

Thank you for the video :) Unfortunately for me, I don’t know which one of my TPMS has a bad battery, so maybe I will do 1, 2, 3 or 4x the labor 😢

[@JOE-bz9un]

4:11 dude wow nice tutorial

[@ericastanton2010]

after replacing battery, will your car recognize the TPMS or does it need to be reprogrammed to a TPMS MACHINE SCANNER

[@bobthepromoter]

the car will recognize the sensor after you change the battery, thats the whole thing is that you don't need to re program everything after changing the battery as you would if changing the whole sensor

[@Siggydawg]

Interesting…. but at 26$ for 4 new and almost getting 16 yrs out of a set, it worth to buy 4 new ones and keep it simple 👍

[@EivinSukoi]

Why didn’t you use the heat iron to desolder the tabs 😬😬😬??.

[@jameshendrix8217]

they are spot welded on not soldered on
