What You’ll Need to Change Your Mazda Key Fob Battery

A small flat-head screwdriver

Pro Tip from John Smith, ASE Certified Master Technician: “Always make sure you’re using a brand-name battery for your key fob. Cheaper batteries may leak or die quickly, leaving you stranded.”

Steps to Change the Battery in Your Mazda Key Fob

Follow these simple instructions to change your Mazda key fob battery.

Locate the release button on the back of your key fob. It’s usually a small, round button.
Press the release button and gently pull out the emergency key. This will separate the key from the main fob.
Carefully pry open the key fob casing. Use the flat-head screwdriver to separate the two halves of the fob. There’s usually a small notch where you can insert the screwdriver.
Locate the old battery. It will be sitting in a small compartment, usually secured with a clip.
Remove the old battery and note the positive (+) and negative (-) sides. Make sure the positive side of the new battery faces the same direction as the old one.
Insert the new battery into the compartment. Ensure it’s securely in place.
Snap the two halves of the key fob casing back together. You should hear a click when it’s properly closed.
Reinsert the emergency key into its slot.

Testing Your New Mazda Key Fob Battery

After replacing the battery, test all the functions of your key fob to ensure it’s working properly.

Troubleshooting Tips: If your key fob still isn’t working after changing the battery, here are a few things to check:

Battery Orientation: Double-check that the new battery is inserted correctly with the positive and negative sides facing the right direction.
Battery Contacts: Ensure the battery contacts inside the key fob are clean and free of debris. You can use a cotton swab and rubbing alcohol to clean them gently.
Programming: In rare cases, you may need to reprogram your key fob after changing the battery. Refer to your owner’s manual for instructions or contact your local Mazda dealership.
