How to Change Battery in 2021 Honda Civic Key Fob

Is your 2021 Honda Civic key fob acting up? Before you run to the dealership, a dying battery might be the culprit. Luckily, replacing it is a quick and easy fix you can do yourself. This guide will walk you through the simple steps to get your key fob back in top shape and your Civic starting smoothly.

Replacing the battery in your key fob is a small task that can make a big difference. Let’s dive into exactly how to change the battery in your 2021 Honda Civic key fob.

What You’ll Need

A small flathead screwdriver
A fresh CR2032 battery (easily found at most supermarkets, drugstores, and online retailers)

Locating the Battery Compartment

Grab your 2021 Honda Civic key fob and locate the small release button on the back.
Gently press the release button. This will allow you to separate the physical key part of the fob from the main body.
Once separated, you’ll see the battery compartment nestled inside.

Replacing the Battery

Carefully wedge the flathead screwdriver into the small notch on the battery compartment cover.
Gently pry open the cover. Be careful not to use excessive force, as this might damage the fob.
Inside, you’ll find the CR2032 battery. Note which side is facing up, as the new battery needs to be placed in the same way.
Using your fingers or the edge of the screwdriver, carefully remove the old battery.
Place the new CR2032 battery into the compartment, ensuring it’s facing the correct direction (the same way the old battery was positioned).
Align the cover and press down firmly until you hear a click, indicating it’s securely closed.

Testing Your Key Fob

Put the physical key piece back onto the main fob body.
Test your key fob by attempting to lock and unlock your car doors. If successful, congratulations! You’ve successfully replaced your key fob battery.

Troubleshooting Tips

Key fob still not working? Double-check that the new battery is properly seated in the compartment and facing the right direction.
Make sure the battery you are using is a CR2032. Using the wrong type of battery may result in improper function.
Avoid touching the battery terminals. Doing so can drain its energy.
