Step-by-Step Guide to Mazda CX-5 Key Fob Battery Replacement
The method to open your Mazda CX-5 key fob varies slightly depending on the model year. Here’s how to access the battery compartment for both newer and older models:
For Newer Mazda CX-5 Models:
Locate the hidden key within your key fob and remove it. You’ll then find a designated slot revealed by removing the key. Insert the key into this slot. This action will allow you to gently pry open the key fob casing.
For Older Mazda CX-5 Models:
If your Mazda CX-5 is an older model, examine the key fob for a small notch. Using a thin, flat object, such as a flathead screwdriver, carefully insert it into the notch. Gently twist or pry to separate the two halves of the key fob casing.

Once the case is open, you’ll see the circuit board and the battery. Carefully lift the circuit board to gain full access to the battery. Before removing the old battery, take a moment to observe its orientation within the case. This will help you install the new battery correctly. Remove the depleted battery and replace it with your new CR2032 or CR2025 battery, ensuring the polarity is correct.
After inserting the new battery, carefully reassemble the key fob casing, ensuring it snaps closed securely. Test the functionality of your key fob by pressing the buttons. If it doesn’t work immediately, double-check the battery connections and ensure they are clean and making good contact.
