Tire stores should have the programing tool, as lots of new cars have this system. It would be a pain to have new tires fitted and then have to go to the stealership and have the program set. Schrader makes and sells the tool required and makes our sensors too, they select the code, do the magnet trick and presto the light should not come on.
You can fix it yourself for free with a bit of black tape.
I have the real tool, not the magnet and it wont reset the light. The tool just excites the sensors so the antenna in the car picks up each signal from each tpms sensor, the body unit registers each one by the serial numbers on the tpms units, only if the numbers are in the unit. it wont recognize a new sensor just by exciting the tpms sensors.
I had to have chrysler reprogram my onboard tpms unit since I had a sensor break. Just using the tool wont make the onboard computer recognize the sensor if its new. With gm cars you can put the car into tpms learn mode your self, but with out cars you cant. you need to have the das/scan tool to do it
