How to change your KeyFob Smart Key battery for your 2017 2018 2019 or 2020 Ford Fusion. This video was on a 2018 Ford Fusion Hybrid. This should work on the Ford Mustang, Explorer and Edge Key fob as well if yours looks just like the one in the video. This specific Keyfob / Smart Key takes a CR2450 battery. You can use a small screwdriver to release the battery very carefully.
