Keep your time and save money!
The device arrived promptly and packaged well. I inserted a 9v battery (new) and followed instructions I found on the internet. My 2025 Chevy Traverse, after a tire rotation, took less the 2 minutes relearn the tire locations and pressures. Great product and a great tool to not visit a dealership that cost money and take time out of your daily schedule.

Flawless for a chevrolet malibu
My tpms sensors started failing one by one. I purchased new sensors on amazon for $20. The mechanic told me because they were aftermarket sensors that his computer would reset the light or recognize the new sensors. They wanted me to buy new sensors from them. Nope, i purchased this little handy tool and not even a minute later my tire pressure warning light turned off and it reset the sensors back to new. For under $10 this tool is a great price and saved me money in the long run. A++++

This tool worked like a charm
Why did you pick this product vs others?:Wow!! This tool is great. Yes, I'd seen the YouTube videos on using a magnet to relearn your car's computer after installing new Tire Pressure Monitoring System (TPMS) sensors in your wheels, but magnets did not work for me. This tool, however, worked like a charm. I followed the included directions and each sensor quickly registered with the computer, one after the other. Now my TPMS is working like it should. My car is a 1999 Corvette and the sensors are Schrader part #29178..

This little tool works like the expensive tools but costs so much less.
2013 Chevy Avalanche Black Diamond LTZ. Bought new rims & tires with new TPMS sensors. My dash light was on. I purchased this tool.Follow instructions. 2 mins later the light is off.Tips: use a brand new battery. You need the extra power. Hold the device on the rubber of the tire. It took 30 seconds to detect signal through the alloy rim, but Antena on the rubber detects in 5 seconds.Now I can rotate my own tires and adjust my sensors in 2 mins.If you are like me you will see tools on here that cost $200 and tell yourself this $6 tool must be junk. It is not junk. It is bare bones with one button and it does the job you ask of it. Battery out, put it in glove box and wait for next tire rotation. DIY simple.

TPMS 2018 Escalade ESV
I used this tool to activate newly installed tpms sensors for 2018 Escalade ESV which worked flawlessly. VXDAS verson did not work which I purchased approx. 1 year ago.

Worked after a few tries
The tire shop rotated my tires on my 2016 GMC Sierra 2500HD but didn't resync the TPMS. Instead of wasting $12 in fuel and 2 hours of my time returning to the shop, I bought this tool. Resyncing was very easy using the instruction in my vehicle's owners manual. I tried several times placing the tool at the valve stem and it did not work. I then moved the tool to the tires rubber side near the valve stem instead of near the valve stem on the aluminum rim side. It then worked flawlessly. I suspect the signal from the tool is very weak and was blocked by the metal rim.
