Solution

1. Preparation

Gather necessary tools: small flat-head screwdriver, a new CR2032 battery.
Ensure the vehicle is turned off to avoid any electronic interference.

2. Open the Key Fob

Locate the seam on the side of the key fob.
Use the small flat-head screwdriver to gently pry open the key fob at the seam. Start at one end and work your way around the fob to fully separate the halves.

3. Remove the Old Battery

Locate the battery compartment inside the key fob.
Note the orientation of the battery (positive side facing up).
Carefully remove the old battery from the compartment using the screwdriver if necessary.

4. Install the New Battery

Insert the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up.
Ensure the battery is seated properly and fits snugly in the compartment.

5. Reassemble the Key Fob

Align the two halves of the key fob together.
Press down firmly around the edges until the fob clicks back into place.
Inspect the fob to ensure it is securely closed.
