This automotive maintenance tutorial was specifically written to assist owners of the second generation 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020 and 2021 Ford EcoSport compact SUV in changing a weak or dead battery in the Intelligent Access or "smart" key fob remote control.

Owners of other Ford or Lincoln vehicles such as the Fiesta, B-Max, Escape, Edge, Bronco Sport, Explorer, Expedition, Transit, Focus, Mondeo, S-Max, Puma, Kuga, Endura, Everest, Ka, Figo, Endeavour, Aviator, Corsair, Nautilus and Navigator may also find these DIY instructions to be helpful.

The compatible replacement coin cell (also known as a "button" or "watch") battery for the smart key fob for this 2020 EcoSport Titanium is part number CR2450 which is available from various manufacturers such as Panasonic, Duracell, Energizer, Sony and Maxell.

Please double check the part number on the old battery in your key fob before ordering a new one. Earlier model years with the standard key fob may instead use the CR2032 battery.

If your SUV is equipped with the older style key fob with a metal ignition key, check out this Ford Escape Key Fob Battery Replacement Guide.

The tools you may need to access and replace the key fob battery include a standard flat head screwdriver or a plastic pry bar tool and a small flat head screwdriver such as from a precision screwdriver set (also known as a "jeweler's screwdriver set").

The first step is to locate the small black plastic release button at the bottom right corner of the smart key fob.

Install New Battery
Orientate the new battery with the "+" positive side facing up towards you and the "-" negative side facing down into the socket.

The OEM (original equipment manufacturer) battery in the fob for this 2020 EcoSport Titanium was a Panasonic CR2450.

Lower the battery into the right side of the socket first.

Then gently pop the new battery down below the two black retaining clips on the left side of the socket.

Make sure the new battery is fully seated in the socket.

Test New Fob Battery
Replace the ignition key into its slot.

The key should "click" back securely into place.

To test the new battery, stand near your SUV and press the "Unlock" or "Lock" buttons.

If the new battery is working properly, you should see the parking lights flashing and also hear the door locks opening and closing.

Be sure to write down the battery change in your vehicle's service records.

(You shouldn't have to re-program the key fob. Just changing the battery should not clear the original programming from the factory.)
