Bought 4 new wheels, discount tires fitted. Programmed and installed in the car, they worked for 4 days before two of them continued to lose signal and caused an error. I contacted the seller, he said to program again. I have made. Then I bought a TPMS retraining device to do it myself. Failed again two days later. I contact the seller, he wants me to do the same thing again and go back to the discount tire. No thanks, I'll just buy two more from another seller because I'm tired of dealing with
