Replacing your key fob battery is much like changing a small household battery. You’ll need a few simple tools and a replacement battery, readily available at most drugstores or online. Let’s get started.
1. Gather Your Tools and New Battery
Before you begin, make sure you have everything you need. You will need:
- A new CR2025 or CR2032 battery (check your owner’s manual or the old battery for the exact type – CR2032 is commonly used for Mazda CX-5 key fobs).
- A small flathead screwdriver, preferably wrapped with a soft cloth or tape to prevent scratches.
Having these items ready will make the replacement process smooth and efficient.
2. Open the Key Fob Casing
The Mazda CX-5 key fob is designed to be opened for battery replacement. Locate the small notch or seam on the side of your key fob. This is usually near the key ring attachment.
Carefully insert your flathead screwdriver into this notch. Apply gentle pressure and twist the screwdriver to pry the two halves of the key fob casing apart. Work your way around the seam slowly to separate the case without damaging it.
