The compatible replacement coin cell (also known as a "button" or "watch") battery is part number CR2032 which is available from various manufacturers such as Sony, Duracell, Energizer, Panasonic and Maxell.

The only tool that is required to complete this procedure is a small flat head screwdriver or a plastic pry bar tool.

I recommend detaching the key ring and your other keys from the loop on the bottom of the fob for easier access to the battery.

Insert the blade of your flat head screwdriver or a plastic pry bar tool into the small notch at the bottom rear edge of the battery cover on the back side of the fob.

Gently pry open the bottom edge of the battery cover.

Set the rear cover aside in a safe place.

Use the small flat head screwdriver or your finger nail to carefully pry the old battery out of its socket.

Try to avoid bending the metal electrical contacts or damaging the green circuit board by scratching it with the screwdriver.

You could also try turning over the fob and tapping it on the table to dislodge the old battery from the holder.

The old battery might be covered with a bit of dielectric grease which helps ensure a reliable electrical connection.

Push the new CR2032 battery into the socket until it is fully seated.

Line up the back cover with the rear of the fob.

Then lower the bottom of the cover towards the loop for the key ring.

Gently pop the cover on to the fob assembly to secure the retaining clips.

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

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

(The key fob should not need to be reprogrammed. Simply replacing the battery should not clear the original programming.)

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