This guide will walk you through the simple steps to replace your Mazda CX-5 key fob battery, saving you time and a trip to the dealership.
Knowing how to change your key fob battery is essential for every Mazda CX-5 owner. When your key fob battery starts to weaken, you might notice symptoms like reduced remote range or needing to press buttons multiple times for your vehicle to respond.

Fortunately, replacing the battery in your Mazda CX-5 key fob is a quick and easy DIY project. You’ll only need a few simple tools and a replacement battery, readily available at most stores. Let’s get started and ensure you’re never caught out by a dead key fob battery again.
What You’ll Need
Before you begin, gather these simple tools:
- A new CR2025 battery. This is the standard battery type for most Mazda CX-5 key fobs.
- A small flathead screwdriver. A precision screwdriver or even a butter knife will work. Just ensure it’s not too sharp to avoid damaging the key fob.
- A soft cloth (optional). This can help protect the key fob from scratches during the process.
Step-by-Step Guide to Replacing Your Mazda CX-5 Key Fob Battery
-
Locate the Notch on Your Key Fob: Examine your Mazda CX-5 key fob. You’ll find a small notch, typically on the side or bottom of the fob. This notch is where you’ll insert your flathead screwdriver to open the casing.
-
Carefully Pry Open the Key Fob: Wrap the tip of your flathead screwdriver with a soft cloth to prevent scratches. Gently insert the screwdriver into the notch and twist to separate the two halves of the key fob casing. Don’t force it; apply steady pressure until the case begins to split.
-
Remove the Old Battery: Once the key fob is open, you’ll see the battery. Take note of the battery’s orientation (+ side up or down) before removing it. You can usually gently pry the old battery out with your finger or the tip of the screwdriver if needed.
-
Insert the New Battery: Take your new CR2025 battery and insert it into the battery compartment in the correct orientation you noted earlier. Ensure it sits snugly in place.
-
Reassemble the Key Fob: Carefully align the two halves of the key fob casing and press them firmly together until they snap back into place. Ensure the case is securely closed.
-
Test Your Key Fob: Test your key fob by pressing the lock and unlock buttons to ensure it’s working correctly. Your Mazda CX-5 should respond as expected.
Tips and Considerations
- Battery Type: Always use the correct CR2025 battery for your Mazda CX-5 key fob. Using a different type might not work or could damage your key fob.
- Gentle Handling: Be gentle when prying open the key fob casing to avoid damaging the plastic clips.
- Battery Orientation: Pay close attention to the battery’s orientation when removing the old one and ensure you insert the new battery in the same way.
- If you encounter difficulties: If you’re having trouble opening your key fob or replacing the battery, consult your Mazda CX-5 owner’s manual or seek assistance from a qualified mechanic or Mazda dealership.
Conclusion
Replacing the battery in your Mazda CX-5 key fob is a simple maintenance task that any owner can perform. By following these easy steps, you can ensure your key fob remains functional and avoid the inconvenience of a dead battery.
