Honda Civic Key Battery Replacement Guide (2014 – 2020)

Introduction

Replacing the key fob battery in a Honda Civic is a straightforward process. This guide will walk you through the steps required to change the battery in the smart key fob used in Honda Civics from 2014 to the present.

The key fob requires a CR2032 coin battery. You can easily purchase this battery online or at a local store.

Materials Needed

Before you begin, ensure you have the following materials:

• CR2032 coin battery
• Valet key (included with your key fob)

Step-by-Step Instructions

Step 1: Remove the Valet Key

First, locate the small notch on the back of the key fob. This notch is a little knob that you can pull towards you.

Pulling this knob will release the valet key from the key fob. Remove the valet key and set it aside for the next step.

Step 2: Pry Open the Key Fob

With the valet key removed, look for the slot between the two pieces of the key fob. The key fob is designed to come apart easily.

Insert the valet key into this slot. Twist the key gently to pry the two pieces apart. This will give you access to the internal battery.

Step 3: Remove the Old Battery

Once the key fob is open, you will see the CR2032 battery. Use the valet key to gently pop out the old battery.

Make sure to dispose of the old battery properly, as it contains materials that can be harmful to the environment.

Step 4: Insert the New Battery

Take the new CR2032 battery and ensure the positive side (marked with a “+”) is facing towards you.

Insert the battery under the larger prongs first, then press it down to secure it in place. Make sure it is firmly seated.

Step 5: Reassemble the Key Fob

With the new battery in place, align the two halves of the key fob and press them together until they snap securely.

Reinsert the valet key into its slot. Your key fob should now be fully functional with the new battery.

Tips and Tricks

Use the Valet Key for Leverage

The valet key is a useful tool for prying open the key fob and removing the battery. Its small size and sturdy construction make it ideal for this task.

Check Battery Orientation

Always ensure the new battery is inserted with the positive side facing up. Incorrect orientation can prevent the key fob from functioning properly.

Test the Key Fob

After replacing the battery, test the key fob to ensure all functions work correctly. This includes locking/unlocking the doors and starting the engine.

Common Issues and Solutions

Key Fob Not Functioning

If the key fob doesn’t work after replacing the battery, double-check the battery orientation. Ensure the battery is seated correctly.

If the issue persists, the new battery may be defective. Try another CR2032 battery from a different package or supplier.

Difficulty Opening the Key Fob

If you have trouble prying open the key fob, use a small flathead screwdriver instead of the valet key. This can provide additional leverage.

Battery Not Staying in Place

If the battery doesn’t stay in place, ensure it is fully inserted under the larger prongs first. This helps secure the battery properly.
