Question is, what did they mean by "reset".
They either tried clearing the code causing the light to come on but it came back or they tried programming the new sensor IDs in the new wheels to your FX but it didn't take.
One thing to note, there's two types of sensors. There's the ones that are on the 2009 - 2011 FX's, then there's the 2012+ sensors. If the wheels came off a FX that was from the earlier years, you'll need to pickup four "newer" sensors for this to work on your 2013.
The two different sensors are on two different frequencies which is why you can't interchange them
If anyone's interested in almost new TPMS sensors, let me know, I'll point you to a guy I bought them from.
