I have done some searching around and can not find a direct answer so I will see if anyone might know here. I have a 2007 RL and my TPMS sensors just took a crap on me so I ordered Schrader TPMS (315 MHz) from Advanced Auto Parts and Mr. Tire is going to charge me $60 to retrain all 4 of the sensors to my car. I have read that the system is self learning and that would not require them to retrain the sensors. Has anyone on here used these tpms sensors and did they just self learn to the factory system?

Thanks
