TPMS Relearn Tool for GM Tire Sensor, Automotive Tire Pressure Monitor Sensor Activation Reset Tool EL-50448 OEC T5, System Programming Training for Most GM Series Vehicles, Car Accessories.

Very easy to use, does exactly what it says it will. Only have vauxhall Astra k. And a mokka 2023 and worked on both. Feels solid enough with no way to get it wrong. Very quick to reprogram. Cheaper than getting a garage to do!!

Arrived day after ordering it along with a battery (don't forget the battery - old PP3 type) and put it to use in my wife's Corsa which even after having a new TPMS Valve fitted in her wheel/tyre, still kept showing the amber Low Pressure indicator on the dash as well as constantly saying Service Tyre Pressure system. Pain in the bahookie - MOT garage failed it and fitted the new valve but didn't have the Re-Learning tool. I bought it on Amazon for less than a tenner, put the battery in, set up the re-learning system as per car's manual, took 3 minutes to do it all. Job done, winner winner, chicken dinner! Saved myself a possible £60, perhaps £120 at a dealers. Worked first time.Edit: Just thought I'd run through the process in using this to re-set the TPMS system.Use the menu button and the turn wheel on the Indicator stalk to get to the tyre pressure page on the wee screen on the dash behind the steering wheel - once you have all the tyre pressures shown, you'll probably have one that doesn't show anything but dashes, if there has only been one valve re-installed like ours was. On that page, hold down the button in the end of the stalk until you get "Activate re-learn system" and the wee orange tyre light will start flashing. Get out of the car and starting at the front left hand or passenger side tyre hold the tool to the tyre just where the valve is and hold the wee white button - it should flash for some seconds then when set will stady and the car horn will beep once, that's to show success. Now move to front right hand side or drivers side and repeat the process, moving on to right rear and then left rear until all the tyres are re-set with a double beep of the car horn. Once inside the car you will see all the tyre pressure have a pressure number, usually P.S.I., and the orange light plus the "Service Tyre Monitoring System will no longer be nagging you. Job Done - a great wee tool.

Worked like a charm on my Mokka X 2017. After i last had the tyres changed they swapped the two rear tyres round. I didn't notice until way later when i needed to put air in and it was showing up on the wrong side on the dashboard display. This little tool saved a lot of messing around and the whole process took less than 5 Minutes. Put the car in learning mode, go to the side of the car with the indicator that's lit up. Touch to the tyre and press the button. Horn beeps and then on to the next one its indicating for you to do. Rinse and Repeat and now all showing the correct pressure values for the correct tyre position.

My parents had one valve and TPMS sensor replaced on their 2015 Mokka and the garage didn't know how to let the car know a new sensor had been fitted. They just told my parent to drive for a bit and the light will go off...They then talked to Vauxhall who quoted them £120 to look at it and reset the system....I then got involved and found this tool for under £10 and though it's worth a try...Very simple to use and worked a treat...had all 4 sensors reprogrammed to the vehicle in under 2 mins, all warning lights are now off, and the system is happy!The only down side is there were no instructions included with the tool. But the ones listed here on Amazon are more than adequate.Great product, I would highly recommend...

This tool actually made the issue worse. One of my sensors stopped working after using this costing me £75 for a replacement. Avoid at all costs. Instantly flung in the bin.

Bought battery, put them in sadly didn't work on our mokka until after we took to garage to get new part for tyre. Light was still on but we used the battery and it worked it reset it

I've just had 4 new tyres on my wife's car on the driveway and noted that after he'd left that one of the 2 tyres were not in the correct orientation right side but wrong end of the car!I thought about swapping the wheels but saw a YouTube video using this tool to reprogramme the car with the wheels in the correct orientation.It is so simple to do and the whole process took about 5 minutes. this is a game changer for me as the TPMS batteries will start running out in the next year or two and that would have been costly to get a Vauxhall dealer to install and programme the car - now I can buy them and get them fitted and reprogramme the car myself. As one reviewer said, there is no + or - indication on the battery clip so the picture shows which is which along with the offside front and rear tyre pressures being reversed! Buy it for under £9 you have so much to gain and nothing to lose apart from a trip to the post office if it doesn't work on your car!

Works well simple to use.
