I could never get her to work on my mother's 2009 Ford Escape. I bought two different programmers that were recommended to work with these sensors and put the car in programming mode, but they never synced. I would return them but not worth taking them out of the hoop. I'll try to install them with forscan or I'll just shut down the system altogether. In the end, I blame Ford. Honda and GM make better TPM systems and that will probably put me off buying another Ford. From what I've found, Ford Genuine TP sensors should last seven years or 150,000 miles.
