Changing your key fob battery is a routine maintenance task that can prevent unexpected lockouts and keep your Mazda 3’s keyless entry system functioning flawlessly. A dead key fob battery can be a real headache, especially if you’re in a hurry. Knowing how to change the battery yourself can save you time and money. Let’s dive into the details.

Locating the Right Battery for Your 2014 Mazda 3 Key Fob

Before you begin, it’s crucial to identify the correct battery type for your 2014 Mazda 3 key fob. The required battery is a CR2025 3V lithium battery. These are readily available at most electronics stores, pharmacies, and online retailers. Purchasing a few extra batteries allows you to have replacements on hand, preventing future inconvenience.

Step-by-Step Guide to Replacing the Battery

Follow these simple steps to change the battery in your 2014 Mazda 3 key fob:

1. Locate the small notch or slot on the side of your key fob. This is usually located near the key ring.
2. Insert a small flathead screwdriver or a key into the notch and gently pry open the key fob casing. Be careful not to damage the plastic. If you’re having trouble, try using a thin piece of plastic, like a credit card.
3. Once the casing is separated, you will see the battery compartment. The CR2025 battery is usually held in place by a small clip or pressure.
4. Carefully remove the old battery. Note the orientation of the positive (+) and negative (-) sides of the battery.
5. Insert the new CR2025 battery into the compartment, ensuring the positive (+) and negative (-) sides are correctly oriented, matching the position of the old battery.
6. Snap the key fob casing back together. Ensure it closes securely with a click.

Testing Your New Key Fob Battery

After replacing the battery, test all the key fob functions, including locking, unlocking, and panic button. If any of these functions aren’t working, double-check the battery installation and ensure the casing is completely closed.

“A common mistake people make is not paying attention to the battery orientation. Make sure the positive (+) side is facing up, just like the old battery,” advises John Smith, a seasoned automotive locksmith at KEYFOBPROG.

What if the Key Fob Still Doesn’t Work?

If your key fob still doesn’t function correctly after replacing the battery, there might be other issues, such as a damaged key fob or a problem with the car’s receiver. You might need professional assistance in such cases. Consider checking out our guide on 2014 mazda 6 key fob replacement for further information.
