Ford Flex Key Fob Battery Remote Replacement 2009 – 2019

The Ford Flex reminds me of my old Scion xB, but on steroids. The large box of an SUV has massive room and visibility, and thankfully, some pretty easy key fob batteries to change! The Flex has had just two key models in it’s first decade of life, and both take the small CR 2032 battery. If you have another Ford car, check out our Ford Fob Batteries guide.
