Yaris Key Fob Battery Change: A Comprehensive Guide

Changing the battery in your Yaris key fob is a simple task that can save you time and money. This guide will walk you through the process, covering everything from identifying the correct battery type to programming your key fob afterward. Whether you’re a car owner, mechanic, or automotive technician, this guide provides the information you need to tackle this common issue effectively.

Understanding Your Yaris Key Fob

Before you begin, it’s important to understand the different types of Yaris key fobs and their corresponding batteries. Different Yaris models and years may use different key fobs, and using the wrong battery can damage your key fob.

Identifying Your Key Fob Type

Toyota Yaris key fobs generally fall into two categories: the standard key fob with a flip-out key and the smart key/push-button start fob. Knowing which type you have is crucial for selecting the correct replacement battery. The standard key fob usually uses a CR2032 battery, while the smart key often utilizes a CR2025 or similar battery. Check your owner’s manual for the specific battery type for your Yaris model.

Signs of a Low Battery

Recognizing the signs of a dying key fob battery can prevent frustrating lockouts. Some common indicators include:

• Reduced key fob range: You might need to be much closer to the car for the key fob to work.
• Intermittent operation: The key fob may work sometimes but not others.
• Dim or no indicator light: The LED light on the key fob may be fainter than usual or not illuminate at all.

How to Change a Yaris Key Fob Battery

Now that you’ve identified your key fob and confirmed a low battery, let’s get to the replacement process. This is a straightforward procedure, but be careful not to damage the key fob components.

Step-by-Step Instructions

1. Gather your tools: You’ll need a small flathead screwdriver and the correct replacement battery.
2. Open the key fob: Carefully insert the flathead screwdriver into the designated notch on the key fob. Gently pry the two halves of the fob apart. Be careful not to scratch or damage the plastic.
3. Locate the battery: The battery is usually housed in a small compartment within the key fob.
4. Remove the old battery: Use the flathead screwdriver to gently pry the old battery out of its compartment. Avoid puncturing the battery.
5. Install the new battery: Place the new battery into the compartment, ensuring the positive (+) side faces up (or as indicated in the key fob compartment).
6. Reassemble the key fob: Align the two halves of the key fob and press them together firmly until they snap shut.
7. Test the key fob: Try locking and unlocking your car to ensure the new battery is working correctly.

Programming Your Key Fob (If Necessary)

In some cases, you may need to reprogram your key fob after changing the battery. This process varies depending on the Yaris model and year. Refer to your owner’s manual for specific instructions. Typically, this involves a sequence of actions using the key fob and the car’s ignition.

Troubleshooting Common Issues

Even with careful execution, you might encounter some hiccups. Here’s how to address common issues:

• Key fob still not working: Double-check that you’ve installed the correct battery type and that it’s positioned correctly in the compartment. If the problem persists, you may need to reprogram the key fob.
• Key fob damaged during battery change: If you accidentally damage the key fob, you may need to replace it. Contact a Toyota dealership or a qualified locksmith for assistance.

“A common mistake people make is using the wrong battery type. Always double-check your owner’s manual or consult a professional to ensure you’re using the correct battery for your specific Yaris model,” says John Smith, Senior Automotive Technician at Smith Auto Repair.
