Item works great for GM cars and Trucks
This item allowed me to reprogram my 2015 Camaro rims TPMS installed in my 2014 Equinox. Took me 10 minutes once I entered the programming mode on Equinox. First fill tires to oem psi, enter programming mode, start at drive front, hold programmer near valve stem, horn will beep once it registers the sensor, continue to passenger front, passenger rear, then driver rear, on the last one horn will beep once registered, and then with a light delay beeps twice the the relearning process is complete. Pretty simple compared to the other methods. This item worked great and was at a really great price!

Compatible With GM Vehicles
Has worked on both my GM vehicles with no issue (2015 Buick Encore and 2015 Chevy Cruze). Looks and works exactly like the OE one we used at the dealership in my lube tech days. Worth it especially for the price. If you have access to a tire changer but the guy doesn't have or use a TPMS relearn tool, you can relearn them yourself with this tool and save yourself a few bucks that way.

Worked Great!
I was trying to avoid being overcharged by the auto shops to perform a very simple tire pressure monitoring system tire position re-learn, so when I saw this tool for $5, I thought what have I got to lose! Followed the included directions to a tee and the process could not have been quicker or smoother. I made sure by using my multimeter that the 9 volt battery (remember, battery is NOT included) I had was well over the 9 volt mark, as the instructions and other reviewers have indicated that it must be a new, fresh battery or the device won’t work. Pulled the car out of the garage and onto the driveway to avoid any radio frequency interferences, as is stated in the instruction manual. After placing my vehicle in the tire position re-learn mode, I started with the left front (driver’s side), then right front, followed by right rear and finally the left rear, each time touching the tool’s antenna onto each tire where the rim and tire meet, next to and parallel to each tire’s valve stem. Make sure to hold the white button on the tool down until you hear each tire make the horn blow indicating it has been accepted into the system. The entire procedure took less than 5 minutes. Well pleased!

Great product
Works just as it should. It is easy to use to get you tire pressure right especially if they rotated your tires and didn’t relearn the sensors

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.
