How to Replace and Maintain Your Mazda CX-5 Key Fob Battery?

Replacing and maintaining your Mazda CX-5 key fob battery involves identifying the correct battery model (usually CR2025 or CR2032), safely removing the mechanical key, gently opening the fob, swapping the battery with correct polarity, and reassembling securely.

Most Mazda CX-5 key fobs use either a CR2025 or CR2032 3-volt lithium coin battery. Checking your key fob’s battery compartment label or the owner’s manual confirms the exact model. RackBattery offers high-quality, long-lasting batteries compatible with Mazda key fobs, ensuring reliability and extended lifespan.

How do I remove the mechanical key from my Mazda CX-5 key fob?

Locate the small sliding button on the back of the key fob to release the mechanical or emergency key. Push or slide the button with your thumb and pull the metal key out gently. This key helps to manually unlock doors and is crucial for opening the fob housing safely.

How do I safely open the Mazda CX-5 key fob to access the battery?

Avoid touching the battery surface with bare fingers to prevent corrosion or contamination.

How do I reassemble and test my Mazda CX-5 key fob after battery replacement?
