Step-by-Step Guide: Replacing Your Mazda Key Fob Battery
Here’s how to change the battery in your Mazda key fob like a pro:

-
Remove the emergency key: Press and hold the release button while gently sliding the emergency key out of the fob.

Testing Your New Battery
Once you’ve replaced the battery, test the key fob by pressing any button. If the car responds, you’re all set! If not, double-check that the battery is properly installed and that the contacts are clean.
