Introduction

Replacing the key battery in your Honda CR-Z is a straightforward process. Whether your key fob is not working or you just want to ensure it doesn’t fail unexpectedly, following these steps will guide you through the process.

In this guide, I will provide detailed instructions on how to replace the battery in the physical key fob used in the Honda CR-Z models from 2011 to 2014.

Required Tools and Materials

Before starting, make sure you have the following items:

• CR1616 coin battery
• Precision screwdriver set
• Flathead screwdriver

You can purchase the CR1616 coin battery and the precision screwdriver set online. Links to these items are available in the video description.

Step-by-Step Instructions

Step 1: Remove the Small Screw

First, flip the key over. You will see a small screw at the base of the key. Using a precision screwdriver, carefully remove this screw. It might take a bit of effort, but once it’s out, the rest of the process will go smoothly.

Set the screw aside in a safe place to avoid losing it.

Step 2: Separate the Key Fob

Next, take a flathead screwdriver and locate the notch in the middle of the base of the key. Insert the flathead screwdriver into this notch and twist gently. You will notice the base of the key fob starting to move.

Pull the base towards you and then flip it up. This will detach the base from the key fob easily.

Step 3: Remove the Internal Section

Now, you can pull out the internal section of the key fob. Set the outer case aside.

Look at the internal section of the key fob. In the upper right corner, you will find a small notch in the middle.

Step 4: Open the Internal Section

Using the flathead screwdriver again, insert it into the notch and twist. This will separate the two pieces of the internal section, giving you access to the coin battery.

Step 5: Replace the Battery

With the internal section open, use the flathead screwdriver to pop out the old CR1616 coin battery. Take the new CR1616 battery and place it into the slot, ensuring the positive side is facing down.

The battery should snap into place easily.

Step 6: Reassemble the Key Fob

Now that the new battery is in place, you can start reassembling the key fob. First, snap the internal section back together.

Then, align the internal section with the outer case. Make sure to start from the top, aligning the top ridge first. This will make it easier to close the case.

Step 7: Secure the Screw

Finally, replace the small screw you removed earlier. Tighten it securely, but be careful not to overtighten and strip the screw or the plastic.

Once the screw is back in place, test the key fob to ensure it’s working correctly. You should see the red light come on when you press the buttons.

Common Issues and Troubleshooting

Sometimes, even after replacing the battery, you might encounter issues with the key fob. Here are some common problems and their solutions:

Key Fob Not Working

If your key fob is still not working after replacing the battery, try the following:

• Check the battery orientation
• Ensure the battery is properly seated
• Inspect for any visible damage

Difficulty in Removing the Screw

If you have trouble removing the screw, make sure you are using the correct precision screwdriver. Applying gentle pressure and turning slowly can help prevent stripping the screw.

Case Not Closing Properly

If the key fob case is not closing properly, ensure that all internal components are aligned correctly. Starting from the top ridge can make it easier to close the case.
