Owning a 2017 Mazda 6 means enjoying sleek design and a smooth ride. However, even the most reliable cars need some TLC, like changing the key fob battery. A dead key fob battery can leave you stranded, so knowing how to replace it yourself is a handy skill. This guide will walk you through the process of changing the battery in your 2017 Mazda 6 key fob, ensuring you’re never left out in the cold.

Signs You Need a New Mazda 6 Key Fob Battery

Before we dive into the replacement process, let’s look at some telltale signs that your key fob battery is on its last legs:

Decreased Range: You find yourself standing closer to your car to lock or unlock it.
Intermittent Functioning: The key fob works sometimes but not others, leading to frustrating inconsistencies.
Warning Light on Dashboard: Some Mazda models display a warning light on the dashboard, indicating a low key fob battery.
No Response: The key fob completely stops responding, and you’re left fumbling with the physical key.

If you’re experiencing any of these issues, it’s highly likely your key fob battery is the culprit.

What You’ll Need for the Battery Replacement

The good news is that changing your Mazda 6 key fob battery is a quick and easy process. Here are the tools you’ll need:

A new CR2025 battery: This is the standard battery for most Mazda key fobs.
A small flathead screwdriver: You’ll need this to pry open the key fob casing.

Step-by-Step Guide: Replacing Your 2017 Mazda 6 Key Fob Battery

Now, let’s get down to business. Follow these simple steps to replace your Mazda 6 key fob battery:

Locate the small release button on the back of your key fob. This button is usually located near the key ring hole.
Press the release button and gently pull out the metal emergency key. This will expose a small slot on the side of the key fob.
Insert the flathead screwdriver into the slot and gently pry open the key fob casing. Be careful not to damage the plastic clips holding the casing together.
Locate the old CR2025 battery inside the key fob. It will be sitting in a small compartment.
Gently remove the old battery and install the new one, making sure to match the ‘+’ side up. This is crucial for the key fob to function correctly.
Carefully align the key fob casing halves and press them together until they snap shut.
Test all the buttons on your key fob to ensure it is working correctly. If everything is working, you’re good to go!

Tips for a Smooth Battery Replacement

Here are a few additional tips to ensure a hassle-free battery replacement:

Avoid touching the battery terminals: This can shorten the lifespan of the battery.
Dispose of the old battery properly: Car batteries contain hazardous materials and should never be thrown in the regular trash.
Consider having a spare key fob battery on hand: This will save you from any unexpected lockouts in the future.

Common Issues and Troubleshooting

While replacing your Mazda 6 key fob battery is usually straightforward, you might encounter some issues. Here’s a quick troubleshooting guide:

Problem: The key fob still doesn’t work after replacing the battery.

Solution:

Double-check the battery orientation: Make sure the ‘+’ side is facing up.
Inspect the battery contacts for corrosion: Clean any corrosion with a cotton swab and rubbing alcohol.
Try reprogramming the key fob: Refer to your owner’s manual for instructions on how to do this.

Problem: You’re having trouble opening the key fob casing.

Solution:

Ensure you’re using the correct screwdriver size: Using a screwdriver that’s too big can damage the casing.
Try applying gentle but firm pressure: The casing might be a bit stiff, especially if it’s the first time you’re opening it.
