Solution

1. Preparation

Tools Required: Small flat-head screwdriver, new battery (commonly CR2032).
Ensure you are working in a clean, well-lit area.

2. Open the Key Fob

Use the small flat-head screwdriver to carefully pry open the key fob casing along the seam.
Start at one end and gently work the screwdriver around the fob to release the clips without damaging the plastic.

3. Remove the Old Battery

Once the key fob is open, locate the battery.
Note the battery orientation (positive and negative sides).
Carefully remove the old battery by lifting it out with your fingers or the screwdriver.

4. Install the New Battery

Place the new battery in the same orientation as the old one, ensuring it fits snugly in the compartment.
Press down gently to ensure it makes good contact with the terminals.

5. Reassemble the Key Fob

Align the two halves of the key fob casing.
Press the two halves together firmly until you hear a click, indicating that the clips have re-engaged.

6. Test the Key Fob

Press the buttons to ensure the key fob is functioning correctly.
Test the range by attempting to lock and unlock the vehicle from a distance.
