What Size Battery Does My 2017 Mazda 3 Key Fob Use?

How Can I Tell if My Key Fob Battery Needs Replacing?

Several signs might indicate that your 2017 Mazda 3 key fob battery is dying. Here are a few things to look out for:

Intermittent Functionality: The key fob may work sometimes but not others, or you may experience lag when using it.

How Do I Change the Battery in My 2017 Mazda 3 Key Fob?

Replacing the battery in your 2017 Mazda 3 key fob is a quick and easy process. Here’s a step-by-step guide:

Locate the small notch or slot on the side of the key fob. This is usually located near where the metal key inserts.
Insert a small flat-head screwdriver or a coin into the notch and gently twist to pry open the key fob.
Carefully separate the two halves of the key fob to reveal the battery.
Note the orientation of the battery (positive (+) side up).
Gently remove the old battery and install the new CR2025 battery, ensuring the positive (+) side faces up.
Align the two halves of the key fob and press them firmly together until you hear a click.

Expert Tip from John Miller, Senior Automotive Technician: “When replacing the battery in your key fob, be careful not to touch the metal contacts on the battery or inside the key fob. This can damage the contacts and shorten the lifespan of your battery.”
