Introduction

Replacing the battery in your Toyota Land Cruiser key fob is a simple process that you can do at home. This guide will walk you through each step, ensuring that your key fob functions seamlessly. All you need is a CR2032 coin battery and a flathead screwdriver.

Gather Your Tools

Before you begin, make sure you have the necessary tools:

• CR2032 coin battery
• Flathead screwdriver

You can purchase the CR2032 battery online. I recommend getting it from Amazon for a few bucks. A link to the battery is provided in the description.

Step 1: Remove the Internal Key

First, flip the key fob over. You’ll notice a small switch. Hold down this switch while pulling out the internal key.

Once the key is out, you will see a large hole and a smaller slot beside it. This slot is where you will insert the flathead screwdriver.

Step 2: Open the Key Fob

Insert the flathead screwdriver into the slot beside the keyhole. Twist the screwdriver gently while holding the key fob loosely. This action will help you pry apart the two halves of the key fob.

Once you have a gap, use your fingers to pull the two halves apart carefully.

Step 3: Remove the Circuit Board

Inside the key fob, you’ll find a circuit board. Carefully remove this circuit board to reveal the battery underneath.

Step 4: Extract the Old Battery

Now, take your flathead screwdriver and insert it between the battery and the black plastic behind it. Hold the key fob by the sides and apply constant pressure with the screwdriver.

Wiggle the screwdriver to get under the battery and pry it out. You can also twist the screwdriver if needed. Once the battery is loose, pull it out with your fingers.

Step 5: Insert the New Battery

Take your new CR2032 battery. Ensure the positive side is facing up. Place the battery into the slot where the old battery was located.

Make sure the battery is securely in place before proceeding to the next step.

Step 6: Reassemble the Key Fob

Place the circuit board back into its original position. Align the two halves of the key fob and press them together until you hear a click.

Finally, insert the internal key back into its slot. Your key fob is now ready to use!

Conclusion

Replacing the battery in your Toyota Land Cruiser key fob is a straightforward process. With a CR2032 battery and a flathead screwdriver, you can complete the task in just a few minutes.
