Replacing the battery in your 2021 Honda Accord Sport key fob is a simple procedure that requires minimal tools. Here’s a step-by-step guide to help you through the process:
-
Gather Your Tools: You will need a small flathead screwdriver or a similar tool to gently pry open the key fob. Of course, you’ll also need a new CR2032 battery.

Locate the Notch: Examine your Honda Accord Sport key fob. You’ll find a small notch, usually on the side or bottom of the fob. This notch is designed to help you open the case.

Install the New Battery: Insert the new CR2032 battery into the compartment, making sure the polarity is correct (match the + and – signs). It should snap into place easily.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob case and press them firmly together until they snap back into place. Ensure the case is fully closed and secure.
