Toyota Corolla Key Fob Battery Replacement (2010 – 2013)

Introduction

Changing the battery in your Toyota Corolla key fob is a straightforward process. You don’t need to be a tech expert to do it. In this guide, I will show you how to replace the battery in your key fob for the 2010, 2011, 2012, and 2013 models.

All you need is a flathead screwdriver and a CR1632 battery. If you prefer to buy the battery online, I’ve included a link to purchase it conveniently from Amazon.

Gather Your Tools

Before you start, ensure you have the necessary tools. You will need:

• Flathead screwdriver
• CR1632 battery

These items are readily available. If you don’t have a CR1632 battery, you can find one online for a few dollars.

Remove the Internal Key

The first step is to remove the internal key from the fob. Look at the side of the key fob and find a button labeled “push.” Press and hold this button while pulling out the internal key.

Set the internal key aside. You will see a keyhole and a smaller indentation in the plastic, perpendicular to the keyhole.

Open the Key Fob

To open the key fob, insert the flathead screwdriver into the smaller indentation. Hold the device loosely in your hand and twist the screwdriver. This action will crack open the key fob.

Once the key fob is open, set it aside. You will see a small circuit board inside. The battery is located under this circuit board.

Remove the Circuit Board

To access the battery, you need to remove the circuit board. You can either knock it out gently or use the screwdriver to lift it from the corner where there is a small space.

Be careful while lifting the circuit board to avoid damaging any components.

Replace the Battery

Now that you have access to the battery, use the flathead screwdriver to pry it out from the top corner. Place your finger on the battery to prevent it from popping out.

Once the old battery is removed, take your new CR1632 battery. Ensure the positive side is facing up when you insert it into the key fob.

Click the new battery into place. Make sure it is secure and properly aligned.

Reassemble the Key Fob

With the new battery in place, it’s time to reassemble the key fob. Start by placing the circuit board back into its original position. Ensure it is seated correctly.

Next, align the two halves of the key fob and press them together until they click into place. Make sure the edges are flush and the fob is securely closed.

Finally, reinsert the internal key into the key fob. Your key fob is now ready to use with the new battery.

Conclusion

Replacing the battery in your Toyota Corolla key fob is a simple process that can save you time and money. Instead of going to a dealership, you can do it yourself at home with minimal tools.
