Solution

1. Preparation

Gather necessary tools: flathead screwdriver, small Phillips screwdriver.
Ensure you have the correct replacement battery (typically CR-V models use CR2032 type).

2. Open the Key Fob

Locate the seam on the key fob.
Use a flathead screwdriver to gently pry apart the two halves of the key fob. Insert the screwdriver into the seam and twist slightly to create an opening.
Be careful to avoid damaging the casing.

3. Remove the Old Battery

Once the fob is open, locate the battery compartment.
Note the orientation of the battery (positive and negative sides).
Using the small Phillips screwdriver, remove any screws holding the battery in place, if applicable.
Carefully lift out the old battery using your fingers or tweezers.

4. Install the New Battery

Insert the new battery into the compartment, ensuring it is oriented correctly (positive side facing up).
If there were screws holding the battery in place, reattach them securely.

5. Reassemble the Key Fob

Align the two halves of the key fob back together.
Press down firmly until the halves snap back into place.
Ensure no gaps are visible and the fob feels secure.
