The Mazda CX-3 key fob typically uses a CR2032 battery. This small, coin-shaped battery is commonly found in various electronics, including car key fobs.

How to Replace Your Mazda CX-3 Key Fob Battery

Replacing your Mazda CX-3 key fob battery is a quick and easy process that you can do yourself at home. Here’s a step-by-step guide:

Remove the old battery: Carefully remove the old CR2032 battery from its compartment. Note the orientation of the positive (+) and negative (-) sides.
Insert the new battery: Place the new CR2032 battery into the compartment, ensuring the positive (+) side faces up, matching the orientation of the old battery.

That’s it! You’ve successfully replaced your Mazda CX-3 key fob battery.

Tips for Extending Key Fob Battery Life

While key fob batteries have a limited lifespan, here are a few tips to help you maximize their longevity:

Avoid frequent short trips: Short trips don’t allow your car battery to fully charge, which can put a strain on your key fob battery as well.
Don’t leave your key fob in extreme temperatures: Extreme heat or cold can impact battery performance.
Keep your key fob away from electronic devices: Other electronic devices can interfere with the signal and drain the battery.
