A replacement coin cell (A.K.A. "button" or "watch") battery is part number CR2032.

The only tool needed to access and replace the battery is a small flathead screwdriver.

Separate Two Halves
Pry Out Old Battery
Old Battery Removed
Insert the blade of the small flathead screwdriver in to the notch on the bottom right edge of the fob near the red "Panic" button.

Gently pry apart the two halves of the fob and turn over the rear cover to expose the old battery.

Either pull out the old battery with your finger nail or gently pry it out with the small flathead screwdriver.

Try to avoid damaging the metal electrical contacts with the screwdriver.

Maxell CR2032 3V
"+" Positive Side Down
Push In New CR 2032


Push a new # CR2032 3 volt coin cell battery in to the holder on the rear cover of the fob.

Make sure the "+" positive side is facing down and the "-" negative side is facing up towards you.

New CR2032 3V batteries are available from a variety of manufacturers such as Panasonic, Maxell, Energizer, Sony, GE and Duracell.

Double check that the new battery is securely installed in to the socket.

Line Up Two Halves
Snap Together Key Fob
Test New Key Fob Battery
Line up the two halves of the key fob and gently pop them back together.

Make sure that the front and rear of the key fob are flush together at every edge.

To test the new key fob battery, stand near your Acadia and press the "Unlock" and "Lock" buttons.

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