What You’ll Need to Change the Battery

A replacement battery: Refer to your Subaru owner’s manual or look up the exact model of your key fob online to find the correct battery type. CR2032 batteries are commonly used.
A small flat-head screwdriver: This will help you pry open the key fob casing.
Optional: A plastic pry tool: This can help prevent scratching your key fob casing.

Step-by-Step Guide to Changing Your Subaru Key Fob Battery

Locate the Battery Compartment: Most Subaru key fobs have a small release button or notch on the back. Use your fingernail or a flat-head screwdriver to gently release the back cover.
Identify the Battery: Once the back cover is removed, you’ll see the battery. Note its orientation (positive (+) and negative (-) sides).
Remove the Old Battery: Carefully pry out the old battery using the flat-head screwdriver or plastic pry tool. Avoid touching the battery’s flat surfaces.
Install the New Battery: Insert the new battery into the compartment, ensuring the positive (+) side faces up, matching the orientation of the old battery.
Reassemble the Key Fob: Align the back cover and press it firmly back into place until you hear a click, indicating it’s securely closed.

Common Issues and Troubleshooting

Key Fob Still Not Working?

Check Battery Orientation: Ensure the new battery is installed correctly with the positive (+) and negative (-) sides in the right direction.
Clean the Contacts: Over time, battery contacts can accumulate dirt or corrosion. Use a cotton swab and rubbing alcohol to gently clean the contacts inside the key fob.
Reprogram the Key Fob: Some Subaru models may require reprogramming after a battery change. Consult your owner’s manual for instructions.
Seek Professional Help: If you’ve tried all the steps and your key fob still isn’t working, there might be a more complex issue. Contact a qualified Subaru dealership or automotive locksmith for assistance.
