Solution

1. Preparation

Gather the necessary tools: a small flathead screwdriver, a new CR2032 battery, and a clean workspace.
Ensure that you are in a well-lit area to see small components clearly.

2. Open the Key Fob

Use the small flathead screwdriver to gently pry open the key fob along the seam, starting at one end and working your way around the fob.
Be careful not to damage the plastic casing or internal components.

3. Remove the Old Battery

Once the key fob is open, locate the battery compartment.
Carefully note the orientation of the existing battery (positive and negative sides).
Remove the old CR2032 battery by gently lifting it out with your fingers or the screwdriver.

4. Install the New Battery

Take the new CR2032 battery and insert it into the compartment, ensuring it matches the original orientation (positive side facing up).
Ensure the battery is seated firmly in place.

5. Reassemble the Key Fob

Align the two halves of the key fob and press them together until they click securely.
Make sure there are no gaps along the seam, indicating a proper seal.

6. Test the Key Fob

Stand near the vehicle and press the lock/unlock buttons on the key fob to ensure it operates correctly.
Confirm that all functions are working, including any panic or trunk release buttons.
