My word I thought you sliced your thumb off! I was doing an HVAC job one time and “2” of my buddies said don’t hold the cutter that way you gonna slice your hand open! I said, “no I won’t!” Not 5 seconds later I sliced my hand open! I just said, “Welp y’all were right!!” I sliced my hand wide open! Lucky I didn’t cause nerve damage! Very Lucky! Stay safe and thanks for the video! 🔪😎

2008 Lexus RX400h, followed your instructions replaced all 5 (including spare tire), a little cumbersome at first but after doing the spare first as a test the rest went pretty easy. Batteries came from EBAY. Dash lights went out as soon as i started the car no programming required and saved me $500 bucks

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.

I applaud you keeping a TPMS out of a landfill but that was a messy job!!!

That was clever how you took TPMS out of the tire. I learned something there!

How clever of you to remove the tire pressure sensor! superb! thank you very much!

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.

Update: I saw one fellow use a shop vac hooked to some 3/8" vinyl tubing with a funnel and then pushed the other end of the tubing on the tire stem with the valve removed, after 6 minutes of suction it deflated the tire enough for him to push the tire off the bead and replace the TPMS without removing the tire from the car.

Worked like a champ! Replaced all five. I used a small sharp screwdriver to slowly work off the welds. First one took a bit but flew through the others.

Great video, the light comes and goes and I’m good with that , I’ve had pressure gages for 50 years and they still work , I’ll live with the light . Oh I did check the dealer $250

Great Information for not even saving money but making easier without reprogram it. Thanks!

We live in 2022 while this man lives in 3022! Great video - battery replacement is easy, but getting the sensor out was a hard idea for me. Nice trick - thanks for sharing!

Great instructional video from begging to end. You show the how to take tire off which I really appreciate.

Great info, scary knifing. That was too close man.

Awesome, I've done this in my motorcycle before. Glad you didn't slice your thumb open when that weld gave way. I've lost a knuckle that way.

Thanks, I gotta try this before having Costco install and register new ones. Plus another excuse to buy a solder from Harbor Freight.

I was bleeding even before he started to attack the TPM with that utility knife.Had to get Band-Aids just to watch this.

Great video. I would add to get a TPMS reader to ensure the sensor is operational again, after soldering the new battery.

Excellent video! Completed all 4 today

Thanks for making this awesome video. Buuuuuut I am going to just buy new ones at Costco for $40 after watching you almost slice your hand open.

This is impressive! My light is on.. no matter how many times I hit reset. My batteries are most def cooked.. you are the first video I came across that shows that you can actually change the batteries.. very informative video.. and yeah, it looks, quite difficult

Most excellent explanation & presentation! TU!

good job on this hack. just a tip: when you heat the solder, you can just heat the metal tab, and it will heat up the solder, so your not trying to heat in between both parts. The heat will transfer and liquefy the solder and just hold it down with the pick to smash the solder.

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.

I’ll just keep driving around with my check system light on. No matter how annoying it is lol 😆 great video tho!

Just at Wal-Mart Auto Center - I was told that 3 of the 5 tires on my 2012 Toyota Rav 4 had bad batteries on the sensors. They quoted $45 per tire to replace the batteries. He also said they see this a lot of on Toyota vehicles over 7 years old. I did not have the batteries replaced yet.

Thanks for the informative video. I am now know that I will be buying news ones instead.

Hello, Thank you for the video. Is your replacement battery still working in your tire TPMS sensors?

You can use a small wire brush attached to a drill to clean out that old silcone Which connection is positive and which is negative ? Kind of important !

Good works! Thank you

Great helping video, which silicone you used, kindly share link too. Thanks

Thanks man, showing us options on saving the environemnt and money. This lessen man made trash impact. 🙌

nice job man 👍

Excellent video 📹!

Thank you sir!

Thanks for the video

Hey Thanks for the video. Its been 2 years since this video, is your sensor still working?

Thank you very much .

Beautiful.thanks dude

I have a 2016 Tundra & every time the tires need replacing, these things seem to get damaged. I gave up as soon as I heard the price for the first one... a bit of black tape over the LED on the dash costs $0.00001... job done.

Batteries aren't cheap in the UK - cost me about a tenner each per tyre. But I'm sure overall this method is still worth it compared to alternative.

A lot of job but that trick to remove the valve was awesome.. I didn't expect that

Ingenious indeed!

Nice! Good way to save a buck and avoid the reprogramming. But I was cringing watching that box cutter part - if someone did that in my shop I would give them shit! But it worked. I might clamp the sensor to a workbench with a rag and a C-clamp if it was me and I didn't want to risk my hands. Good results though 👍

Very cool, thanks for sharing!

whats the latest update with your repaired tpms sensors??

Muchas gracias es un buen video.

Hello I have one question. Do you think is enough space to install BR 2477 battery. The diameter is the same but the height is 7.7 mm not 5mm. In my country I didn't find 2450. Thanks

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

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

Amazing video you gave done as this info is so hard to find especially the type of battery needed to buy before replacing which im hunting for to save double job time. Wanting to know how the sensors worked after all this and was it beneficial time wise or was there issues not long after doing job?

Jesus wept Man, My testicles were in my throat watching your handy knife work!!!! but very helpful anyway. Thanks.

spot tac welders for making battery packs and strip of nickel one strip on both sides use 4-6 spot welds would work as well. not sure if i want to invest spot welder probaly should need laptop battery and already purchesed 6X 18650 26oo mAh lishen cells i think all new) i dont want to spend around 100 dollars for laptop and up to 100 each tpms sensors W/ programming . thanks for sharing the tip for button cell with tabs installed didn't know you get button cells like that.

How they holding up? Wondering if a larger capacity battery that meets or exceeds the size specs will be a better option? Guessing a 2477 won't fit. Reads like the CR2450 has a capacity of 600 mAh, while the CR2450N has a capacity of 540 mAh.

McGiver lives!!

Great tip & video. I was afraid that blade was going slice your hand though. Too bad car and parts manufacturers don’t make those sensors so you could easily replace batteries. Such a waste but I know all the care about is making money. All the best.

After replacing the battery,does the sensor needs to be programmed to the vehicle again?do i need programming tool?

Thanks for this great video. I tried to beat the tire but the other end of wheel will jump up. No chance to get the tire off. I will try later again

Thank you

Can I use RTV silicone. They use it for gaskets so I know its good for high Temps.

Sad and pathetic they make the battery such a pain to replace. Thanks for the video.

Worker: Hey boss, this food says it expired yesterday. I really don't think we should be feeding it to our customers. Boss: 3:49

Not to be the one to ask the silly question here but are you supposed to take every wheel off and do this to the tyre to find out which one has an issue with the battery? Should I just replace all four instead as the other three will probably need replacement anyway sooner or later?

Will the same batteries do a 2014 Toyota avensis sensor?

I love seeing people going to the hospital with utility knife injuries. How much is a finger?

4:11 dude wow nice tutorial

I am little worry about the last step where the water goes inside the tire and make it unbalance. Do you know what kind of stuff they put at the tire shop between the rim and the tire?

Walmart replaced mine $28 per tire. Sensor and installation.

Thank you for good idea. Please let me know how do you find out which one was low battery? Do we have to buy a $$$ tpms relearn tool to find out it? I have a low battery in tpms sensor tires but don’t know exactly which one to replace the battery.

Genius!

Hi Bob, thank you so much for this great idea. While the battery link has sold out the battery. I only find a EEMB LIR 2450 battery with tab on Amazon. The differences are like these. Your battery is 3V, 550mAh, non rechargeable. And this LIR 2450 is 3.7V, 120mAh, rechargeable. Can I use this LIR2450? Thank you very much.

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

How to find the right type/model of battery for 09 Toyota Corolla LE?

Thanks for the great video. that being said... I would not sweat the weight and just have the wheels balanced directly after replacing the TPMS batteries. Also, you might want to make sure to replace ALL of the sensors batteries at the same time (INCLUDING YOUR SPARE TIRE) as they often ALL fail within a very short time frame.

Thanks cuh

can you use a cr2045 which I found on amazon

How did you check to see if the new battery and the sensor was working after you soldered the battery in?

Awesome video dude!

Got scared when he was playing with that razor

Likely the mass diff from the Silicone, but is it reqd or any possible substitute? Respects to your ingenuity & appreciate the info. A few areas to reduce risk & safety along with improving process but you motivate self-sufficiency involving an industry scam, the TPMS.

Thank you!!! Worked perfectly for my 2014 Lexus ES350. The job is more annoying than complex.

Dude that was close 😅, that knife was sharp

Мне вот интересно, что дешевле, обратится на шиномонтаж где извлекут датчик, или пришить пальцы в случае если не повезет и покрышка встанет на место?

Very nice! How many minutes did it take to complete one tpms?

Great video ,what voltage is the original battery ? 3volt ?

Who was the POS that gave you thumbs down? Good video , the blade was really close to your hand. Gracias mate . Keep it up .

Nice video. How is the new battery holding up?

Works dangerously. Best to buy original sensors I think

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?

When you soldered the battery, was the bottom of the battery pos. Or neg?

Is the tpms still working?

Is the battery the same part# for all Toyotas or should I dismantle one of my tpms before ordering? Specifically I'll need replacement batteries for a 2005 4Runner and 2010 RAV4.

What happens if the fixed sensor is a few grams too light / heavy?

You need liquid flux to get a good solder joint on the battery!

Doesn’t that will damage the tire?

Did it work?

Hi buddy where to buy the battery? Is it just normal button cell ?

Soapy water great idea to show if bubbles stay then air is slowly leaking adter

I’m used to solder and mod Dreamcast ps1 ps2 mod chips and modify electric scooters and messing with battery cells and building battery pack with spot welder so this is up to my ally. And I sure as hell not buying a 200 cord and software just to use it once or pay someone eles to do it
