AICEL TPMS Relearn Tool EL-50448 for GM Tire Pressure Sensor, Orange

This TPMS tool works as it should. When using it, point it at the sensor next to the tire not the rim. Also, if you have a new sensor that doesn't want to read, give it a couple days of driving. On my Silverado, the right rear sensor wouldn't read. And the computer wouldn't acknowledge the 3 that were read. So I tried it a few days later and it read the 4th sensor. Hope this helps someone.

Did not work at all. Useless.

we have a 2022 xt 6 we got used and someone rotated the tires and didn't relearn the positions and it annoyed the heck out of me for the last year. this handy device took care of it in like 5 minutes.

This product did not work for me at first, after trying for a half an hour. I found the secret was NOT to put it parallel to the valve stem, but to go UNDERNEATH it on the sidewall of the tire. I believe this is the issue that people claiming it did not work were experiencing. (Although there may have been other reasons). Videos showed it being used parallel to the valve stem. This is not the way to do it. I am assuming that the metal from the rim blocks the signal, so you need to go to below the stem, on the sidewall of the tire itself. The tire itself is obviously less dense, thus allowing the signal from the hand held unit to penetrate to the sensor inside the of the tire. Once I figured that out, (And I held it SIDEWAYS, not head on.) it took me all of about 90 seconds to do all 4 tires. YAY. That saved me a 36 mile trip to the tire shop in order to have them do it, and it will now save me the 36 mile trip and $20 cash every time I rotate my tires. I am most pleased indeed. The price I paid for this was less than half of what a tire shop charges in my area, and I can do it now each and every time I need to.

Very great item to add to your tool box and saves you from going to pay for a program at dealerships or tire stores, works perfectly fine on your resets if needed and very easy to use, while programming you’ll her it beep and car will actually honk for you as you reset it on tire stems, price very budget friendly and a great purchase for me, very fast shipping

Didn't work - had to return it. I read other reviews and they were mixed so I decided to try myself. But it was no go so it went back.

Probably works, but with no clear instructions, how can I use it? It says to be sure the "learn" function is on in the car, but gives no clue about how to do that. Pretty useless...

Worked like it should

No instructions probably because TPM setup is vehicle specific. I used YouTube to work out what to do with my truck. I should have bought this years ago
