Were installed on my 2010 F150 with a new set of tires and wheels. One of the sensors did not connect to my truck. Tried the tire shop 3 times but the front left one didn't connect. He also had trouble connecting the front right side to the pair, which occurred intermittently. I can't return them as they are built into my bikes. Now my TPMS in my truck is not working and every time I drive I get a warning and a light which is very frustrating.
