Boost Your Highlander’s Performance: A Step-by-Step Guide to Changing the Key Fob Battery in Your Toyota Highlander 2019

The dreaded “click” of a dying key fob battery is a familiar sound for many Toyota Highlander 2019 owners. While it might seem intimidating, replacing your key fob battery is a simple task that can be done in minutes. This guide will walk you through the process step-by-step, so you can get back to enjoying the convenience of your keyless entry system.

Why You Need to Change Your Key Fob Battery

A dying key fob battery can make your life a lot more difficult. You’ll have to manually unlock your doors, and the key fob’s range will be significantly reduced, making it harder to start your car. In some cases, a completely dead battery can even prevent your key fob from working altogether.

Tools You’ll Need

Before you begin, gather the following tools:

• A small flathead screwdriver or a coin: This will be used to pry open the key fob.
• A new CR2032 battery: This is the standard battery size for Toyota Highlander 2019 key fobs.

Step-by-Step Guide to Replacing the Battery

Now, let’s get started:

1. Locate the Key Fob’s Battery Compartment: Your Toyota Highlander 2019 key fob has a small seam or groove on one of its sides. This is where the battery compartment is located.

2. Open the Key Fob: Use your flathead screwdriver or coin to gently pry open the key fob along the seam. Be careful not to apply too much force, as you could damage the key fob.

3. Remove the Old Battery: Once the key fob is open, you’ll see the old battery. Carefully pull it out of the compartment.

4. Insert the New Battery: Take your new CR2032 battery and insert it into the compartment, ensuring the positive (+) side faces up.

5. Close the Key Fob: Once the new battery is in place, gently close the key fob. Make sure the seam is properly aligned and the key fob snaps shut securely.

Testing Your Key Fob

Now that you’ve replaced the battery, it’s time to test your key fob.

1. Unlock Your Doors: Try unlocking your car doors using the key fob. If it works, you’re good to go!

2. Start Your Car: If you’re using a push-button start system, try starting your car with the key fob.

3. Check the Range: Test the range of your key fob by walking away from your car and seeing how far you can get before the signal starts to fade.

Key Fob Battery Life

The lifespan of a key fob battery can vary depending on factors like usage and temperature. However, you can expect a CR2032 battery to last for 1-2 years on average. If you notice your key fob’s range decreasing or the buttons becoming sluggish, it’s probably time to replace the battery.

Tips for Extending Battery Life

Here are a few tips to help you extend the life of your key fob battery:

• Avoid Extreme Temperatures: Heat and cold can affect battery life. Try to keep your key fob out of direct sunlight and extreme temperatures.
• Minimize Button Presses: Use your key fob sparingly. If you can, try to unlock your doors manually when possible.
• Store Your Key Fob Correctly: When you’re not using your key fob, store it in a cool, dry place.

Taking Care of Your Key Fob

In addition to replacing the battery, there are other things you can do to take care of your key fob and ensure it lasts for years to come:

• Keep It Clean: Wipe down your key fob regularly with a damp cloth to remove dirt and grime.
• Avoid Dropping It: A dropped key fob can damage the internal components, so try to handle it carefully.
• Protect It From Water: Keep your key fob away from water and moisture.
