How to Replace the Battery in a Toyota RAV4 Key Fob (2019-2021)

Introduction

Replacing the battery in your Toyota RAV4 key fob is a simple task that you can do at home. This guide will walk you through the steps to open the key fob and replace the internal battery. Whether your key fob has three or four buttons, the process remains the same.

Tools and Materials Needed

• CR2032 battery
• Flathead screwdriver
• Precision screwdriver
• Optional: Paper clip, bobby pin, or toothpick

Step 1: Remove the Internal Key

First, locate the small switch on the bottom of the key fob. Hold down the switch and pull out the internal key. Set the key aside for now.

Step 2: Open the Key Fob

Now that the internal key is removed, you will see a keyhole. Directly opposite the keyhole, there is a small indentation in the plastic. This is where you will insert your flathead screwdriver.

It’s best to have the back side of the key fob facing up, not the button side. Insert the flathead screwdriver into the indentation and twist it to pop open the key fob. Remove the back cover and set it aside. Be cautious as the buttons may fall out; keep everything oriented correctly.

Step 3: Remove the Old Battery

With the key fob open, locate the small hole above the battery. Use a precision screwdriver to pry the old battery out. If you don’t have a precision screwdriver, you can use a paper clip, bobby pin, or toothpick. However, a precision screwdriver is recommended for ease and to avoid damage.

Step 4: Insert the New Battery

Take a new CR2032 battery and place it into the slot with the positive side facing up. Ensure the plus sign is visible once the battery is in place.

Step 5: Reassemble the Key Fob

Now that the new battery is in place, it’s time to reassemble the key fob. Align the back cover with the front part of the key fob and click them together. Ensure everything is snug and secure.

Finally, insert the internal key back into its slot. Your key fob should now be fully functional with a new battery.
