Solution

1. Preparation

Gather necessary tools: flathead screwdriver and a replacement battery (CR2032).
Ensure you are in a well-lit area to see the key fob components clearly.

2. Open the Key Fob

Locate the small slot on the side of the key fob.
Use the flathead screwdriver to gently pry open the key fob at the slot.
Carefully separate the two halves of the key fob, taking care not to damage the casing.

3. Remove and Replace the Battery

Identify the old battery in the key fob and note its orientation (positive and negative sides).
Using the flathead screwdriver, gently lift and remove the old battery from its compartment.
Insert the new CR2032 battery in the same orientation as the old one, ensuring the positive side (+) is facing up.

4. Reassemble the Key Fob

Align the two halves of the key fob back together.
Press down firmly but gently until the halves snap back into place.
Ensure that all edges are flush and the casing is secure.

5. Test the Key Fob

Stand within range of the vehicle and test the key fob buttons to ensure proper functionality.
Make sure the lock and unlock functions work smoothly.
