GL50448 GM TPMS Reset Tool

Tried to re-learn the existing sensors on the used car we got 7 months ago and they just wouldn't sync.A catastrophic even happened and I needed to replace some tires so just got a set of 4 new tires and a set of 4 new sensors that the tire shop could install. Asked the shop to not sync the new sensors so I could use this tool.Tried in the lot before leaving that tire shop and couldn't get the second one to sync so just quit and drove home. Tried again at home and all 4 tires did successfully sync.The tool is very simple with nothing to set, no dials or anything, no way to select which car model or anything. It worked on a Chevy Trax, but one tire, I pressed the button and it hadn't synced yet when the tool timed out. Pressed the button again and it synced that time. I noticed that holding the end of the tool right at the end of the valve stem might have helped it somehow.

Since I sometimes rotate my own tires, I needed a way to relearn the system. On a 2018 Yukon one has to have the relearn tool. For the price this tool is great. Works as it should and saves one time of going to a shop to relearn tpms.

Make sure you position the antenna correctly, it’s critical to do so, unit worked great! Very satisfied

It's not working on my neither my 2015 Chevy Silverado nor 2014 Chevy Cruz. It will beep for the front left wheel sensor but not for any of the others. I have tried multiple times lingering on the front right tire for about 10 minutes. I am disappointed.

I am a happy believer now, looked to easy on the Youtube. Worked like a charm on my C6 Vette. Chevy dealer gave me an estimate of $450. to replace 1- monitor and an additional $50. to install, and some dealers wonder why customers don't trust them. This great product cost me less than $10., service tire monitor dash boards lights are gone. Highly Recommend.

Thank you!

This reset my factory tpms sensors but wouldn’t work on an aftermarket one. At the price I can’t really complain. I eventually took my truck, 2016 Chevy Silverado 2500 HD, and had all sensors replaced since they were 7 years old and the installer reset those.

pressed menu button in car for tire pressure and clr button to tell car to relearn (heard beeps) placed tool on front driver tire near value and pressed button on tools (heard a beep) , next the front passenger tire, rear passeenger tire and than the rear driver tire. heard beeps and was done.when getting tire rotated the shops always forget the relearn the tpms. Now if they forget it will take me a minute to do it. Also I had tire shop replace one of the tpms sensors with one that I purchased. I reprogrammed it using this tool and it worked well
