This comprehensive guide will walk you through everything you need to know about your 2016 Mazda 6 key fob battery, from identifying signs of a failing battery to step-by-step replacement instructions.

Recognizing a Dying Key Fob Battery

Before rushing to the store for a new battery, it’s essential to ensure that the battery is the real issue. Here are some telltale signs indicating your 2016 Mazda 6 key fob battery might need a replacement:

Decreased Range: You need to be much closer to your car for the key fob to unlock or lock the doors.
Intermittent Functioning: The key fob buttons work sporadically, requiring multiple presses.
No Response: The key fob buttons fail to elicit any response from your vehicle.
Dashboard Warning: Some Mazda models may display a “Key Fob Battery Low” warning on the dashboard.

Gathering the Necessary Tools

Replacing your 2016 Mazda 6 key fob battery requires minimal tools, most of which you might already have around the house:

A small flat-head screwdriver: This will be used to pry open the key fob casing.
A fresh CR2025 battery: This is the standard battery type used in many Mazda key fobs, including the 2016 Mazda 6.

Step-by-Step Guide to Replacing Your 2016 Mazda 6 Key Fob Battery

Once you’ve gathered your tools and your new battery, follow these easy steps to replace your key fob battery:

Locate the key fob’s release button: On the back of your Mazda 6 key fob, you’ll find a small button.
Release the metal key: Press the release button and gently slide the metal key out of the fob.
Pry open the key fob casing: Carefully insert the flat-head screwdriver into the seam where the two halves of the key fob meet. Gently twist the screwdriver to separate the halves.
Remove the old battery: Locate the circular CR2025 battery. Note the battery’s orientation for correct placement of the new battery. Gently pry out the old battery.
Insert the new battery: Place the new CR2025 battery into the compartment, ensuring the positive (+) side faces up – the same orientation as the old battery.
Reassemble the key fob: Align the two halves of the key fob and press them together until you hear a click, indicating they’re securely closed.
Reinsert the metal key: Slide the metal key back into its slot on the key fob.

Expert Tip: Avoid touching the top and bottom surfaces of the new battery, as this can transfer oils from your skin and reduce battery life.
