Step-by-Step Guide: How to Open a Mazda CX-5 Key Fob

Locate the release notch: Examine your Mazda CX-5 key fob. There’s a small notch or slot on the side, typically near the key ring. This is the release point for the emergency key blade.
Insert the screwdriver: Gently insert the tip of the small flathead screwdriver into the notch. Be careful not to pry too hard, as you could damage the plastic.
Release the emergency key: Gently twist the screwdriver to release the emergency key blade. The key blade will partially eject from the fob.
Separate the key fob halves: With the emergency key blade partially out, you can now use it to gently pry open the two halves of the key fob casing. Start by widening the gap where the key blade emerged. Work your way around the edge of the fob, gently separating the two halves.
Access the battery: Once the key fob is open, you should see the battery compartment. The battery is typically a CR2032. Note its position for proper replacement.
Replace the battery (if needed): If you’re replacing the battery, carefully remove the old one and insert the new one, ensuring the positive (+) side faces upwards.
Reassemble the key fob: Align the two halves of the key fob and press them together until they snap firmly back into place. Ensure the emergency key blade is fully inserted and functional.
