Knowing the specifics of your key fob battery is the first step in ensuring a smooth replacement.
Battery Type and Specifications
The 2022 Mazda CX-30 key fob battery is a CR2032 3V lithium coin cell battery. This is a widely available and inexpensive battery type that you can find at most drugstores, supermarkets, and online retailers.
Here are the key specifications to remember:
- Battery Type: CR2032
- Voltage: 3V

It’s always a good idea to keep a spare CR2032 battery at home so you’re prepared when your key fob battery starts to weaken.
Recognizing the Signs of a Low Key Fob Battery

Step-by-Step Guide to Replacing Your 2022 Mazda CX-30 Key Fob Battery
Replacing the battery in your 2022 Mazda CX-30 key fob is a simple process that requires no special tools. Follow these steps to get your key fob working like new again:
Step 1: Gather Your Materials
Before you begin, make sure you have the following:
- A new CR2032 battery
- A small flathead screwdriver or a similar thin tool (like a key or a pen)
- A soft cloth to protect the key fob

Step 3: Open the Key Fob Casing
Once the emergency key is removed, you’ll see a small slot or notch where the key was inserted. This is where you’ll use your flathead screwdriver or thin tool.
Carefully insert the tip of your screwdriver into the slot and gently twist. This should start to separate the two halves of the key fob casing. You may need to work your way around the seam, gently prying until the case splits open. Avoid using excessive force, as you could damage the casing.
Step 4: Remove the Old Battery
With the key fob casing open, you’ll see the CR2032 battery. Note the orientation of the battery (usually the positive side facing up). Gently pry the old battery out of its holder. You can use your fingertip or the edge of the screwdriver, being careful not to damage the battery contacts.

Step 5: Insert the New Battery
Take your new CR2032 battery and insert it into the battery compartment. Ensure the battery is oriented correctly, matching the orientation of the old battery you removed (positive side usually facing up). Press down gently until the battery is securely in place.
Step 6: Reassemble the Key Fob
Carefully snap the two halves of the key fob casing back together. Press firmly until you hear a click, ensuring the case is completely closed and secure.
Step 7: Test Your Key Fob
Insert the emergency key back into the key fob. Now, test all the buttons on your key fob – lock, unlock, and panic alarm – to ensure they are working correctly. Your 2022 Mazda CX-30 key fob should now be functioning with a fresh battery.
Troubleshooting and Additional Tips
- Key Fob Still Not Working? If your key fob still doesn’t work after replacing the battery, double-check that you installed the new battery correctly and that it’s the right type (CR2032). If problems persist, there might be an issue with the key fob itself, and you may need to consider a replacement.
- Extreme Temperatures: Extreme hot or cold temperatures can sometimes affect battery performance. If you experience key fob issues in extreme weather, battery replacement might be the solution.
- Professional Programming: While battery replacement doesn’t require reprogramming, if you need to replace the entire key fob due to damage or loss, you will need to have a new OEM Mazda remote professionally programmed by a dealer or a qualified automotive locksmith. This is because modern key fobs like the one for your 2022 Mazda CX-30 have advanced security features that require professional programming to sync with your vehicle’s immobilizer system.
Conclusion
Replacing the battery in your 2022 Mazda CX-30 key fob is a simple maintenance task that can save you inconvenience and potential costs. By following this guide, you can easily keep your key fob working reliably and enjoy the convenience of keyless entry and remote functions. Remember to use the correct CR2032 battery and handle your key fob with care during the battery replacement process. For replacement key fobs and professional programming services, always consult with a trusted source like a certified automotive locksmith or your Mazda dealership.
