This automotive
maintenance tutorial was specifically written to assist owners of the
refreshed first generation (2013, 2014, 2015, 2016, 2017, 2018 & 2019) Ford
Flex crossover SUV equipped with the smart or "intelligent" key fob remote
control for the keyless entry and push button start systems in changing a
weak or dead battery. Owners of other Ford or Lincoln vehicle such as the Explorer, Fiesta, Focus, Fusion, C-Max, Mustang, Taurus, EcoSport, Escape, Edge, Expedition, Transit Connect, F-150, Ranger, MKZ, MKC, Navigator, MKX and Continental may also find these DIY instructions to be helpful. The compatible replacement coin cell (also known as a "button" or "watch") battery part number is CR2032. The only tool needed to open the fob to access and replace the battery is a flathead screwdriver or a plastic pry bar tool. (If you have an earlier 2009, 2010, 2011 or 2012 model year Flex with the standard key fob with a metal ignition key, please take a look at my Ford F-150 Key Fob Battery Replacement Guide.) |

Insert a flathead

Test New Fob Battery |
|
The ignition key
should "click" securely into place. To test the new battery, stand near your vehicle and press the "Unlock" and "Lock" buttons. If the new battery is working properly, you should see the parking lights flash and also hear the door locks opening or closing. (The fob should not need to be reprogrammed. Just changing the battery does not clear the original programming.) Be sure to record the battery change in your vehicle's service records. Please
