Replacing the Key Battery on a 2019 Ford Focus

Model: Ford Focus MK 4 - Years 2018-2025
Part: Key

The video shows how to replace the battery in a 2019 Ford Focus key, but it also applies to a Ford Fiesta. It is a very simple operation, but be careful as, unlike many other remotes, this one has two separate compartments: the emergency blade and the battery compartment. To extract the battery, lever on the side of the key with a small screwdriver, open the key into two parts, and remove the flat battery. Insert the new battery, type CR 2032, in the correct orientation and close the key, aligning the two parts with the help of the pin present in one of the two halves.
