How to Replace the Battery in a Toyota RAV4 Key Fob

Introduction

Replacing the battery in your Toyota RAV4 key fob is a straightforward task you can do at home. This guide will walk you through the process step-by-step. Whether you have the three-button or four-button version, the procedure is the same.

Required Tools and Materials

Before you begin, you’ll need a few items:

• CR2032 battery
• Flathead screwdriver

If you don’t have a CR2032 battery, you can easily purchase one from Amazon.com.

Step-by-Step Guide

Follow these steps to replace the battery in your key fob:

1. Remove the Internal Key

First, locate the small button on the side of the key fob that says “push.” Press this button while pulling out the internal key.

2. Open the Key Fob

Next, you’ll need a flathead screwdriver. Look for the keyhole and find the small slot in the plastic perpendicular to it. Insert the screwdriver into this slot and twist it to open the back part of the key fob.

3. Remove the Circuit Board

Once the back part is off, you’ll see the circuit board that houses the battery. Carefully lift out the circuit board using the flathead screwdriver.

4. Extract the Old Battery

Insert the screwdriver between the battery and the black plastic behind it. Apply gentle, constant pressure while wiggling the screwdriver to pop out the old battery. Be cautious not to touch the delicate parts of the circuit board.

5. Insert the New Battery

Take your new CR2032 battery and ensure the positive side (marked with a plus sign) is facing up. Place it into the slot on the circuit board.

6. Reassemble the Key Fob

Position the circuit board back into the key fob. Snap the two halves of the key fob back together and give it a firm squeeze to ensure they are securely connected. Finally, reinsert the internal key.

Tips and Precautions

Here are some tips to help you through the process:

• Handle the circuit board carefully
• Ensure the new battery is placed correctly
• Check the key fob’s functionality after reassembly
