Changing the battery in your Toyota Auris key fob is a simple task that can be done in just a few minutes. This guide will walk you through the process step-by-step, making it easy for even the most tech-challenged individuals.

Why Your Key Fob Battery Might Be Dying

Before diving into the replacement process, it’s helpful to understand why your key fob battery might be losing its charge. Here are a few common culprits:

• Age: Batteries have a limited lifespan. If your key fob battery is a few years old, it’s probably time for a replacement.
• Frequent use: The more you use your key fob, the faster the battery will drain.
• Extreme temperatures: Heat and cold can shorten the life of your battery.
• Leaving the key fob in direct sunlight: Prolonged exposure to sunlight can also damage the battery.

Gathering Your Supplies

Before you begin, make sure you have the following items on hand:

• A new CR2032 battery: This is the standard battery used in most Toyota Auris key fobs. You can find them at most electronics stores or online retailers.
• A small flathead screwdriver: This will be used to pry open the key fob.
• A clean cloth: This will help you wipe away any dirt or grime from the key fob.

Step-by-Step Guide to Replacing Your Toyota Auris Key Fob Battery

Now that you have everything you need, let’s get started:

1. Locate the battery compartment: On most Toyota Auris key fobs, the battery compartment is located on the back of the key fob. It’s usually marked with a small arrow or a “+” sign.
2. Open the battery compartment: Use the flathead screwdriver to gently pry open the battery compartment. You may need to apply a bit of force, but be careful not to damage the key fob.
3. Remove the old battery: Once the battery compartment is open, you’ll see the old battery. Gently lift it out of the compartment.
4. Insert the new battery: Take the new CR2032 battery and insert it into the compartment, ensuring the positive (+) side is facing up.
5. Close the battery compartment: Gently press the battery compartment closed. You should hear a click when it’s properly secured.

Testing Your New Battery

After replacing the battery, test it to make sure it’s working properly. Press the unlock button on your key fob. If the car unlocks, your new battery is working correctly. If not, double-check that the new battery is inserted correctly and that the battery compartment is closed securely.

Important Tips for Key Fob Battery Care
