How to Replace the Battery in a Toyota Prius Key Fob

Introduction

In this tutorial, I will guide you through the process of replacing the battery in your Toyota Prius key fob. This is a straightforward task that you can easily accomplish at home. You will need a CR2032 battery, which is readily available online or at most electronic stores. Follow these steps, and you’ll have your key fob working in no time.

Tools and Materials

Before we begin, make sure you have the following items:

• CR2032 battery
• Flathead screwdriver
• Precision screwdriver (optional)
• Paperclip, toothpick, or bobby pin (optional)

Step 1: Remove the Internal Key

First, locate the switch at the bottom of your key fob. Hold this switch down to release the internal key. Set the key aside for now, as we will not need it for the battery replacement process.

Step 2: Open the Key Fob

Next, take your flathead screwdriver and look for the keyhole on the fob. This is the larger hole, and beside it, there is a small indentation in the plastic. Insert your screwdriver into this indentation and twist it gently. This action will crack open the key fob.

Once the fob is open, flip it over to remove the internal component that houses the battery. Set this component down on a flat surface.

Step 3: Remove the Old Battery

Now, you need to remove the old battery. There is a small opening at the top of the battery compartment. Insert a small precision screwdriver, paperclip, toothpick, or bobby pin into this opening and pry the battery out. The battery should click out easily.

Step 4: Insert the New Battery

Take your new CR2032 battery and ensure that the positive side is facing up. Insert the battery into the compartment, making sure the plus sign is visible. The battery should sit on top of the small circle with the battery symbol on the back of the device.

Step 5: Reassemble the Key Fob

With the new battery in place, click the top of the key fob back on. Squeeze the two halves together until they click into place. Finally, reinsert the internal key into the fob.
