Step-by-Step Guide to Changing Your Mazda 3 Key Fob Battery

Ready to bring your key fob back to life? Follow these simple steps:

Locate the release button: On the back of your key fob, you’ll find a small button or notch. This is the release button for the key fob cover.
Release the key fob cover: Using your fingernail or the tip of your flat-head screwdriver, gently press the release button. The back cover of the key fob should pop open slightly.
Separate the key fob halves: Carefully separate the two halves of the key fob, taking care not to damage the internal components.
Identify the battery: You’ll see the CR2032 battery nestled inside one of the halves. It’s usually held in place by a small clip or pressure.
Remove the old battery: Using your fingernail or the screwdriver, carefully pry the old battery out of its compartment. Avoid touching the flat surfaces of the battery, as this can reduce its lifespan.
Install the new battery: Place the new CR2032 battery in the compartment, making sure the positive (+) side faces up (usually marked on the battery).
Reassemble the key fob: Align the two halves of the key fob and press them together firmly until you hear a click, indicating the cover is secure.
Test your key fob: Press the buttons on your key fob to ensure it’s working properly. If the buttons still seem unresponsive, double-check that the battery is correctly installed and making good contact.

Pro Tip: “Always store your spare key fob battery in your car’s glove compartment. That way, you’ll be prepared for a dead battery, even when you’re on the go!” – John Smith, Senior Automotive Technician.
