Solution

1. Preparation

Gather necessary tools: a small flat-head screwdriver or coin.
Ensure you are in a clean, well-lit area to avoid losing any small components.

2. Open the Key Fob

Locate the seam on the edge of the key fob.
Insert the flat-head screwdriver or coin into the seam and gently twist to pry open the key fob casing. Be cautious not to damage the plastic.

3. Remove the Old Battery

Once the key fob is open, locate the battery compartment.
Carefully lift the old battery out of its slot, taking note of the battery orientation (positive and negative sides).

4. Install the New Battery

Insert the new battery (typically a CR2032 lithium coin battery) into the compartment, ensuring it is oriented correctly with the positive side facing up.

5. Reassemble the Key Fob

Align the two halves of the key fob casing.
Press the halves together until you hear a click, indicating that the fob is securely closed.

6. Test the Key Fob

Stand near your vehicle and press any button on the key fob to check if it functions correctly.
