This article will show you how to change the battery on Ford key fob remote. There are several Ford remotes but in this case, we will show you how to replace the battery on the Ford Smart Proxy Key which is similar to the flip key that uses the same shell. This Ford Key is used on several models with intelligent access such as Ford Mustang, Ford Fusion, F-150 and many other Ford models.  

These instructions are helpful for owners of Ford and Lincoln vehicles such as the Focus, Fiesta, C-Max, Mustang, Escape, Transit Connect, Edge, Flex, Explorer, Expedition, Taurus, F-150, EcoSport, MKC, MKZ, MKS, MKX, MKT and the Navigator.

New Ford Vehicles Use CR2025 Batteries. We would recommend using CR2025 Energizer Lithium Batteries as they last longer and have great reviews on Amazon.
