Introduction

Replacing the battery in your Toyota C-HR key fob is a simple process you can do at home. Whether your key fob has three or four buttons, the procedure remains the same. In this guide, I will walk you through each step to ensure your key fob is back in working order.

What You Will Need

Before we start, gather the following items:

• CR2032 battery

• Precision screwdriver
• Optional: paper clip

You can purchase these items online. For convenience, here’s a link to the CR2032 battery.

Step 1: Remove the Internal Key

The first step is to remove the internal key from the key fob. Locate the switch at the bottom of the device. Hold down this switch and pull out the internal key. This will expose the keyhole and a small slot in the plastic.

Step 2: Open the Key Fob

Next, you need to open the key fob. Insert a flathead screwdriver into the small slot perpendicular to the keyhole. Hold the device loosely and twist the screwdriver. The key fob should come apart easily. Set the key fob down and remove the rubber component and battery housing.

Step 3: Remove the Old Battery

To remove the old battery, you will need a tool that fits into the small area around the battery. A precision screwdriver works best, but if you don’t have one, a paper clip can also do the job. Insert the tool into the small area and pry the battery out.

Step 4: Insert the New Battery

Now, take your new CR2032 battery. Ensure the positive side is facing up so you can see the text on the battery. Click the new battery into place securely.

Step 5: Reassemble the Key Fob

Once the new battery is in place, it’s time to reassemble the key fob. Place the battery housing back into the rubber component. Ensure the rubber sits securely over the buttons. Click the back of the key fob into place, making sure everything is aligned.

Step 6: Test the Key Fob

Finally, reinsert the internal key into the key fob. The light on the key fob should come on, indicating the new battery is working correctly. If the light does not come on, double-check that the battery is inserted properly.
