Identifying Your Mazda 6 Key Fob

Before you begin, it’s important to identify the type of key fob you have. Mazda 6 models have used different key fob designs over the years, and the battery replacement process may vary slightly. Generally, you’ll encounter either a “flip” key or a “smart” key fob. Knowing which type you have will help you locate the correct instructions and tools.

What Type of Key Fob Do I Have?

A flip key integrates the key blade into the fob itself, while a smart key fob has a separate, detachable key blade. Smart key fobs often have additional features like push-button start. Once you’ve determined your key fob type, you can proceed with the battery replacement. You can learn how to change a 2016 Mazda 3 key fob battery by visiting 2016 mazda 3 key fob battery change.

Gathering the Necessary Tools

You’ll need a few simple tools for the job:

A small flathead screwdriver or a similar tool for prying open the key fob.
A new CR2032 battery. This is the most common battery type for Mazda 6 key fobs.
Optionally, a small pick or tweezers can be helpful for removing the old battery.

Steps to Change the Battery in your Mazda 6 Key Fob

Locate the release button or notch: This is usually on the side or back of the key fob. Press the release button or insert the flathead screwdriver into the notch and gently twist to separate the key fob halves.
Identify the battery compartment: Once the key fob is open, you should see the battery compartment. It’s usually a small, circular slot holding the CR2032 battery.
Remove the old battery: Carefully pry the old battery out using your flathead screwdriver, pick, or tweezers. Avoid damaging the contacts inside the key fob.
Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side is facing up. Press gently until it clicks into place.
Reassemble the key fob: Align the two halves of the key fob and press them together firmly until they snap shut.

Testing the New Battery

After you’ve changed the battery, test all the key fob functions (lock, unlock, panic) to ensure it’s working correctly. For specific instructions on a 2014 Mazda 6, see our guide on 2014 mazda 6 key fob battery change.
