How to Replace a Toyota Highlander Key Fob Battery

Have you ever walked up to your Toyota Highlander, key fob in hand, only to find that your car won’t unlock? Before you panic and start searching for a tow truck, there’s a good chance the issue is simply a dead battery in your key fob. Thankfully, replacing a Toyota Highlander key fob battery is a quick and easy process you can do yourself, saving you time and money. This guide will walk you through each step, making sure you’re back to enjoying the convenience of your keyless entry in no time.

What You’ll Need to Replace Your Toyota Highlander Key Fob Battery

To replace your Toyota Highlander key fob battery, you’ll need just a few things:

• A new CR2032 battery: This is the standard battery for most Toyota Highlander key fobs. You can usually find them at electronics stores, auto parts stores, or even your local grocery store.
• A small flathead screwdriver: This will be used to pry open the key fob casing.

Steps to Replace Your Key Fob Battery

Now that you have your tools, follow these simple steps to change your Toyota Highlander key fob battery:

1. Locate the release button on the back of your key fob. This is usually a small, indented button.
2. Press the release button and gently slide out the metal key from the fob. Set the key aside.
3. Identify the seam or notch on the edge of the fob. This is where the two halves of the casing connect.
4. Carefully insert the flathead screwdriver into the seam and gently pry open the casing. Work your way around the edge of the fob until the two halves separate. Be careful not to damage the casing or internal components.
5. Locate the old battery. It’s typically housed in a small compartment within the fob.
6. Gently remove the old battery and note the orientation of the positive (+) and negative (-) sides. This will ensure you insert the new battery correctly.
7. Insert the new CR2032 battery, making sure the positive (+) side faces up, matching the orientation of the old battery.
8. Align the two halves of the key fob casing and press them together firmly until you hear a click. This indicates the casing is securely closed.
9. Reinsert the metal key into the fob.
10. Test your key fob to ensure it’s functioning properly. Lock and unlock your Highlander a few times to confirm the new battery is working.

Troubleshooting Tips

If your key fob still isn’t working after replacing the battery, here are a few additional things to check:

• Ensure the new battery is properly seated and making good contact.
• Clean the battery contacts inside the fob with a cotton swab and rubbing alcohol. This can help improve conductivity.
• Try reprogramming your key fob to your Highlander. This process can vary slightly depending on your model year, so refer to your owner’s manual for specific instructions.

When to Seek Professional Help

While replacing the battery in your Toyota Highlander key fob is a relatively simple task, there are times when it’s best to consult a professional. If you’ve tried troubleshooting the issue and your key fob still isn’t working, it’s possible there’s a more complex problem at hand, such as a malfunctioning receiver in your vehicle.

You may also want to consult a professional if:

• Your key fob casing is severely damaged.
• You’re uncomfortable working with small electronics.
• You’re unsure about the correct battery type for your key fob.
