Gather the Necessary Tools
Before you begin, it’s important to gather all the tools you will need to change the CX5 key battery. Here’s what you’ll need:

Locate the Battery Compartment
To begin the battery replacement process, you’ll need to locate the battery compartment on your CX5 key fob. The battery compartment is typically located on the back of the key fob. Look for a small indentation or a groove that indicates where the compartment is.
Step 1: Open the Key Fob Case
Using the small flathead screwdriver, carefully insert it into the groove or indentation on the key fob case. Gently twist the screwdriver to pry open the case. Be cautious not to apply too much force to avoid damaging the key fob or the case.
Step 2: Remove the Old Battery
Once the key fob case is open, you will see the battery inside. Carefully remove the old battery from its compartment. Take note of the battery’s orientation, as you will need to install the new battery in the same position.
Step 3: Install the New Battery
Take the new battery and place it into the battery compartment, ensuring that it is properly aligned. Press down gently to secure the battery in place.
Step 4: Close the Key Fob Case
With the new battery installed, it’s time to close the key fob case. Align the two halves of the case and press them together firmly until you hear a click or feel that they are securely fastened.
Testing the New Battery
Once you have replaced the battery and closed the key fob case, it’s important to test the functionality of your key fob. Follow these steps to ensure that the new battery is working properly:
Step 1: Stand Near Your Vehicle
Position yourself near your Mazda CX5, within a reasonable distance for the key fob to send a signal.
Step 2: Test the Lock and Unlock Buttons
Press the lock and unlock buttons on the key fob to check if they are working correctly. If the doors lock and unlock as expected, it’s a good indication that the new battery is functioning properly.
Step 3: Test the Engine Start Button
If your Mazda CX5 has a push-to-start ignition, press the engine start button with the key fob nearby. The engine should start without any issues. If it does not, double-check the battery installation or consult your owner’s manual for further troubleshooting steps.
Additional Tips and Precautions
To ensure a smooth battery replacement process and avoid any potential issues, here are a few additional tips and precautions to keep in mind:
- Always handle the battery with care and avoid touching the battery terminals with your bare hands. Oils and dirt from your skin can potentially affect the battery’s performance.
- If you are unsure about the correct battery type for your key fob, consult your owner’s manual or contact a Mazda dealership for assistance.
