What You'll Need

Before you begin, gather these items:

A new CR2032 battery: This is the standard battery type for most Honda key fobs from this period. You can find these at most electronics stores, supermarkets, or online.
Small flathead screwdriver (or similar prying tool): This will be used to carefully pry open the key fob. A plastic pry tool is ideal to avoid scratching the fob.

Step-by-Step Instructions

Here's how to change your Honda key fob battery:

Step 1: Locate the Key Release Button

Most 2019-2021 Honda key fobs have a small, sometimes almost invisible, button or switch on the side. This button releases the key blade. Locate this button. It's often subtly recessed.

Step 2: Release the Key Blade

Press the small button to release the key blade. The key should pop out slightly, offering a small gap to work with.

Step 3: Separate the Key Fob

Gently pry open the key fob using your small flathead screwdriver or plastic pry tool. Start at the seam where the two halves meet. Apply even pressure along the seam. Don't force it; if it's not coming apart easily, double-check for any hidden clips.

Step 4: Access the Battery

Once the key fob is open, you'll see the battery compartment. The CR2032 battery will likely be held in place by a small metal clip or simply nestled in its compartment.

Step 5: Replace the Battery

Carefully remove the old CR2032 battery. Note the position of the '+' side; this is important for correct polarity. Insert the new battery, ensuring the '+' side is facing upwards (as the old one was).

Step 6: Reassemble the Key Fob

Carefully snap the two halves of the key fob back together. Make sure they align perfectly before pressing firmly. You should hear a slight click when they are securely fastened.

Step 7: Test the Key Fob

Try locking and unlocking your car using the key fob. If everything works correctly, you've successfully changed the battery!

Troubleshooting

Key Fob Doesn't Work After Battery Replacement: Double-check the battery polarity. Make sure the battery is securely seated.
Key Fob is Difficult to Open: Use a thin plastic pry tool to avoid scratching the surface. Try applying even pressure along the entire seam.

This process should be straightforward. However, if you encounter any significant problems, consult your Honda owner's manual or contact a qualified technician. Replacing the battery yourself can save you time and money compared to going to a dealership. Remember to dispose of your old battery responsibly.
