For most 2011 Mazda models, the key fob battery size is CR2032. This small, coin-shaped battery is commonly used in various electronics, including watches, calculators, and, of course, car key fobs.
Important Note: While the CR2032 battery is the most common size for 2011 Mazda key fobs, it’s essential to verify the exact battery type for your specific Mazda model. Refer to your owner’s manual or look for a battery compartment diagram on the back of your key fob.

How to Replace the Battery in a 2011 Mazda Key Fob
Replacing the battery in your 2011 Mazda key fob is a simple task that can be done at home with just a few tools. Here’s a step-by-step guide:
- Gather your tools: You will need a small flat-head screwdriver and a new CR2032 battery.
- Locate the battery compartment: Examine the back of your key fob for a small groove or indentation. This typically indicates the battery compartment cover.
- Open the battery compartment: Gently insert the flat-head screwdriver into the groove and pry open the cover.
- Remove the old battery: Carefully remove the old battery from the compartment, noting the positive (+) and negative (-) sides.
- Insert the new battery: Insert the new CR2032 battery into the compartment, matching the positive (+) and negative (-) sides with the markings in the fob.
- Close the battery compartment: Align the cover and press it firmly until it snaps back into place.
- Test the key fob: Ensure all buttons are functioning correctly by locking and unlocking your car and testing the panic button.
Pro Tip: When replacing the battery, avoid touching the battery’s flat surfaces with your fingers. This can transfer oils from your skin, potentially affecting the battery’s performance.
Maintaining Your Mazda Key Fob
Properly maintaining your Mazda key fob can help extend its lifespan and prevent premature battery drain. Here are some helpful tips:
- Keep your key fob dry: Exposure to moisture can damage the key fob’s internal components, including the battery.

- Replace the battery regularly: Even with proper care, key fob batteries have a limited lifespan. Consider replacing your key fob battery every 2-3 years as a preventative measure.
Still Having Issues with Your 2011 Mazda Key Fob?
While replacing the battery usually solves most key fob issues, there might be instances where the problem lies elsewhere. If you’re still experiencing problems with your key fob, consider the following:
