Locating the Right Battery for Your Subaru Key Fob

First, you need to identify the correct battery type for your specific Subaru model. Most Subaru key fobs use a CR2032 3V lithium battery, but it’s always best to check your owner’s manual or search online using your Subaru’s year and model.

Changing your Subaru key fob battery is straightforward. Most Subaru key fobs have a small release button or notch on the side. Here’s a detailed guide:

1. Locate the release button/notch: Examine your key fob and find the small release button or notch, often located near the key ring.
2. Release the key: Press the release button and gently separate the metal key from the fob. You’ll use the key blade as a lever in the next step.
3. Open the fob casing: Insert the tip of the metal key (or a small flat-head screwdriver) into the notch or slot you identified earlier. Carefully twist or pry open the fob casing. Avoid using excessive force, which can damage the fob.
4. Remove the old battery: Once the casing is open, you should see the CR2032 battery. Gently pry it out using your fingernail or the flat-head screwdriver. Be careful not to damage the battery contacts.

7. Test the fob: Try locking and unlocking your car doors with the key fob to ensure the new battery is working correctly.
