Solution

1. Preparation

Gather necessary tools and materials.
Ensure you have a replacement battery (CR2032 or as specified).
Work in a clean, well-lit area.

2. Open the Key Fob

Using a small flat-head screwdriver or a key fob opening tool, carefully insert it into the seam of the key fob.
Gently twist the screwdriver to separate the two halves of the fob. Take care not to damage the plastic casing.

3. Remove Old Battery

Locate the battery inside the key fob.
Note the orientation of the battery (which side is positive).
Use the screwdriver to gently pry the old battery out from its compartment.

4. Install New Battery

Take the new battery, ensuring it is oriented the same way as the old battery (positive side facing up).
Press the new battery securely into the compartment until it fits snugly.

5. Reassemble the Key Fob

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

6. Test the Key Fob

Stand near the vehicle and test the key fob's functionality (lock/unlock doors).
If it works correctly, the battery replacement is complete.
