Identifying Your Toyota Yaris Key Fob Type

Before diving into the battery replacement process, it’s important to identify the type of key fob you have. Toyota Yaris key fobs come in two main variations:

• Smart Key Fob: This more advanced key fob is typically larger and features a keyless entry system. It might have a small, retractable key blade housed within the fob.

Knowing the type of key fob you have will determine the exact steps involved in battery replacement.

Gathering the Necessary Tools

To change your Toyota Yaris key fob battery, you’ll only need a few basic tools:

• A small Phillips screwdriver: This will be used to open the key fob casing.
• A new CR2032 battery: This is the standard battery used in most Toyota Yaris key fobs. You can find these at most electronics stores or online.

Step-by-Step Guide to Changing the Key Fob Battery

Now, let’s get started with the battery replacement process:

1. Locate the Battery Compartment:

• Standard Key Fob: The battery compartment is usually located on the back of the key fob. Look for a small seam or a release button.
• Smart Key Fob: The battery compartment might be located on the side or the bottom of the key fob. Look for a small latch or a release button.

2. Open the Key Fob Casing:

• Standard Key Fob: Use the Phillips screwdriver to carefully pry open the key fob casing along the seam or release button.
• Smart Key Fob: Locate the release button or latch and press or slide it to open the casing.

3. Remove the Old Battery:

• Gently lift the old battery out of the compartment. Dispose of it properly according to local regulations.

4. Insert the New Battery:

• Align the new CR2032 battery with the positive (+) and negative (-) terminals inside the compartment. The battery should fit snugly.

5. Close the Key Fob Casing:

• Carefully snap the key fob casing back together. Ensure that all the edges are properly aligned.

6. Test the Key Fob:

• Press the unlock or lock button on your key fob to test if the battery is working. If the key fob responds, you have successfully replaced the battery.

Tips and Precautions

Here are some helpful tips and precautions to keep in mind:

• Use a suitable screwdriver: Avoid using a screwdriver that is too large or too small, as it could damage the key fob casing.
• Be gentle: When opening and closing the key fob casing, handle it with care to avoid breaking any delicate parts.
• Dispose of the old battery properly: CR2032 batteries contain mercury and other hazardous materials. Dispose of them responsibly at a designated battery recycling facility.
• Replace the battery regularly: While the battery life can vary, it’s generally recommended to replace the key fob battery every 1-2 years to ensure optimal performance.

Beyond Battery Replacement: Troubleshooting Key Fob Issues

While a dead battery is the most common reason for a malfunctioning key fob, other issues might arise. If your key fob is still not working after replacing the battery, consider the following troubleshooting steps:

• Check the key fob’s range: Try standing closer to your vehicle and pressing the unlock button. If the key fob works at a shorter distance, the antenna might be faulty.
• Ensure the key fob is registered to your vehicle: If you’ve recently purchased a used key fob, it might need to be registered with your Toyota Yaris’s computer system. Consult your owner’s manual or a Toyota dealership for instructions.
• Look for damage: Inspect the key fob for any signs of physical damage, such as cracks, scratches, or water damage. If there is visible damage, the key fob might need to be repaired or replaced.

Keeping Your Key Fob in Top Shape

To ensure your key fob continues to function flawlessly for years to come, follow these simple maintenance tips:

• Avoid extreme temperatures: Extreme heat or cold can damage the key fob’s internal components. Store it in a cool, dry place when not in use.
• Keep it clean: Wipe down the key fob regularly with a soft, dry cloth to remove dirt and debris. Avoid using harsh chemicals or abrasive cleaners.
• Protect it from water: Water damage can be detrimental to the key fob’s electronics. Keep it away from rain, spills, and other sources of moisture.
