Replacing the battery in your key fob

Below are the general steps to replace the battery in a 2019 Honda CR-V key fob. Have a fresh CR2032 battery on hand before starting.

1. Prepare your tools and the new battery: CR2032 3V coin cell.


2. Locate the small seam on the edge of the fob where the two halves meet.


3. Use a small flat-head screwdriver or a fingernail to gently pry apart the two halves. Do not force the plastic.


4. Carefully lift out the old battery, noting its orientation (which side is facing up).


5. Insert the new battery with the correct polarity (the + side typically faces up toward you).


6. Snap the fob halves back together and ensure they click into place.


7. Test the remote by pressing lock/unlock and other buttons to confirm proper operation. If it does not respond, re-check battery orientation or try a fresh CR2032 again.

Important precautions: Avoid touching the battery’s terminals with your fingers to reduce oil transfer, and dispose of the old battery following local recycling guidelines.

Where to buy and cost considerations

CR2032 batteries are widely available at auto parts stores, supermarkets, and online retailers. Expect to pay a few dollars per battery, often less if bought in multi-packs. If you’d rather avoid DIY, a dealership can perform the replacement for a higher service charge.
