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.

Set the ignition key aside in a safe place.

Locate the small notch in between the fob assembly and the back cover.

Very gently pry the rear cover off the back side of the fob assembly.

Use a small flat head screwdriver or your fingernail to gently pry out the old battery from the socket.

Try to avoid bending, damaging or breaking the retaining clips.

Don't scratch the green circuit board situated below the battery or damage the metal electrical contacts.

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.

First, re-insert the small tab on the top edge into place.

Then lower the rear edge and push on it to secure the retaining clips.

Make sure the rear cover is flush with the rest of the fob housing at every edge.

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.)
