Changing your Subaru key fob battery is a quick process. You’ll need a small flat-head screwdriver and a replacement CR2032 battery, which is a common type used in many key fobs.

Locate the release button or notch: Most Subaru key fobs have a small release button or notch on the side. This releases the physical key, which you’ll need to remove.
Remove the physical key: Gently press the release button and slide the key out.
Open the key fob casing: Use the flat-head screwdriver to carefully pry open the key fob casing at the seam where the two halves join. Be gentle to avoid damaging the plastic.
Remove the old battery: The CR2032 battery is usually located in a small compartment. Gently pry it out using the screwdriver.
Install the new battery: Insert the new CR2032 battery, making sure the positive (+) side faces up, which is usually indicated on the battery and inside the key fob compartment.
Close the key fob casing: Align the two halves of the casing and press them firmly together until they snap shut.
Reinsert the physical key: Slide the physical key back into its slot.
Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Troubleshooting Common Issues

Sometimes, even after replacing the battery, your key fob might not work. Here are a few things to check:

Battery Orientation: Make sure the new battery is installed with the positive (+) side facing up.
Key Fob Programming: In rare cases, you might need to reprogram your key fob after replacing the battery. Refer to your owner’s manual for specific instructions. If you’re having trouble with a 2016 Subaru Forester key fob, check out our resources for troubleshooting.
