1. Preparation

Gather necessary tools and parts.
Ensure you have a replacement battery compatible with the Toyota Camry key fob (typically CR2032).
Work in a well-lit area to avoid losing small parts.

2. Open the Key Fob

Use a flathead screwdriver or a coin to gently pry apart the key fob at the seam.
Carefully insert the screwdriver or coin into the slot and twist to separate the two halves of the fob.
Take care not to damage the plastic casing.

3. Remove the Old Battery

Locate the battery inside the key fob. Note the orientation of the battery (positive side facing up).
Use your fingers or a plastic tool to gently lift the battery out of its compartment.

4. Install the New Battery

Insert the new battery into the compartment, ensuring the positive side is facing the same direction as the old battery.
Press down gently until the battery is seated firmly in place.

5. Reassemble the Key Fob

Align the two halves of the key fob and press them together until you hear a click, indicating they are securely closed.
Ensure there are no gaps around the edges of the fob.
