To access the battery, you’ll need to open the key fob casing. Follow these steps:

2. Insert the screwdriver or pry tool: Gently insert the screwdriver or pry tool into the seam and carefully twist or pry to separate the two halves. Apply gentle pressure to avoid damaging the casing or internal components.
3. Pop open the casing: Once the halves are separated, use your fingers to carefully pry open the casing. Be cautious not to apply excessive force as you may break any delicate plastic tabs holding the casing together.

Step 4: Remove the Old Battery

Now that the key fob casing is open, it’s time to remove the old battery:

1. Identify the battery: Locate the battery within the key fob. It’s usually a small, round cell positioned in a specific slot or compartment.
2. Take note of battery orientation: Observe the orientation of the old battery, including the positive (+) and negative (-) sides. This will ensure that you insert the new battery correctly.
3. Remove the old battery: Using your fingers or a non-metallic tool, carefully lift the old battery out of its compartment. Take extra care not to damage any surrounding components or lose any small parts inside the key fob.

Step 5: Install the New Battery

With the old battery removed, it’s time to install the new one:

1. Check battery type and voltage: Verify that the replacement battery matches the specifications required by your Subaru key fob. If it’s the correct battery, proceed to the next step.
2. Insert the new battery: Position the new battery in the same orientation as the old one, ensuring the positive and negative sides align with the corresponding terminals in the key fob. Press it down gently to secure it in place.
3. Close the key fob casing: Carefully bring the two halves of the key fob casing back together. Press firmly until you hear a click, indicating that the casing has snapped shut. Double-check that the casing is properly aligned and flush on all sides.

Step 6: Test the Key Fob

After replacing the battery, it’s crucial to test whether the key fob is functioning correctly:

1. Reattach any keychain attachments: Once the key fob casing is securely closed, reattach any keychains or accessories you removed earlier.
