2014 Buick Verano worked great!
This orange tool worked great and was less expensive than the red one when I purchased. I used this for my 2014 Buick Verano. Worked great and took like 2 minutes. Pressed menu button in car until it showed tire pressure then held down the set button. Asked if I want to re-learn TPMS and selected yes. Went around car, one tire at a time clockwise starting with drivers front followed by passenger front etc... Hold button with unit against tire next to valve stem, after horn beeps then move onto the next tire. 2 horn beeps after last tire then done.

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.

Easy-to-use
Works perfectly. Reprogrammed my sensors in 30 seconds with no problems. Easy DIY, save yourself $150 from the shady ass tire shop won't program your sensors and wants you to use their tpms sensors only.

works!
Worked perfectly once I learned how to turn the reset tpms on in my car using the car fob. Reset all four tire stems in less than 15 minutes.
