i had new rear tires put on my tire pressure sensor is still on how can you reset it

What is your question?

i had 2 new rear tires put on my santa fe, the tire sensor light was on so i thougth that was part of the problem. well the tire shop installed to tires and the light is still on. # 1 how do you reset it? #2 do the sensors go out and do you have to replace them? is there a gadget that resets them??

How long has your 2011 Hyundai Santa Fe had this problem?

2-3 WEEKS and still after the new tires was installed
