Gather necessary tools: small flathead screwdriver or a coin, and a new CR2032 battery.
Ensure you are working in a clean, well-lit area.
Have a soft cloth or mat to place the key fob on to avoid scratches.

2. Open the Key Fob

Use the small flathead screwdriver or coin to gently pry open the key fob at the seam.
Start at one end and work your way around the fob to avoid damaging the plastic.

3. Remove the Old Battery

Locate the old battery inside the key fob.
Note the orientation of the battery (positive side facing up).
Carefully remove the old battery by lifting it out with your fingers or the screwdriver.

4. Insert the New Battery

Take the new CR2032 battery and insert it into the key fob in the same orientation as the old battery (positive side facing up).
Ensure the battery sits snugly in its compartment.

5. Reassemble the Key Fob

Align the two halves of the key fob and press them together until you hear a click, indicating that they are securely closed.
