A small flathead screwdriver or a similar tool for prying open the key fob.
Your Subaru key fob owner’s manual (optional, but recommended for specific instructions).

Locate the key release: On the side of your key fob, you should see a small button or switch. Press this release and slide the metal key out of the fob.
Open the key fob: Use the flathead screwdriver to carefully pry open the key fob casing. Start at the seam where the two halves of the fob meet. Gently insert the screwdriver and twist to separate the halves. Be careful not to damage the plastic.
Remove the old battery: Once the fob is open, you should see the CR2032 battery. Gently pry the old battery out of its compartment using your screwdriver or fingernail.
Install the new battery: Place the new CR2032 battery into the compartment, making sure the positive (+) side is facing up.
Reassemble the key fob: Align the two halves of the key fob and press them together until they snap securely into place.

Troubleshooting Common Subaru Key Fob Issues

Sometimes, even after replacing the battery, your key fob might not work. Here are a few troubleshooting tips:

Check the battery orientation: Ensure the new battery is inserted correctly with the positive (+) side facing up.

Try reprogramming the key fob: Consult your owner’s manual for instructions on how to reprogram your key fob to your car. This is sometimes necessary after a battery replacement.
