Solution

1. Preparation

Gather the necessary tools: small flathead screwdriver or a coin, and a new CR2032 battery.
Ensure you are working in a clean, well-lit area to avoid losing small components.

2. Open the Key Fob

Locate the seam of the key fob where the two halves meet.

Carefully separate the two halves without damaging the casing.

Identify the battery location inside the fob.
Note the orientation of the battery (positive and negative sides).
Gently pry out the old battery using the screwdriver, taking care not to damage any internal components.

4. Install the New Battery

Place the new CR2032 battery into the slot, ensuring that it is oriented the same way the old battery was (positive side facing the correct direction).
Press down gently until the battery is securely in place.

5. Reassemble the Key Fob

Align the two halves of the key fob back together.
Press the two halves together until you hear a click, indicating they are securely closed.
