Understanding Your Mazda 2018 Key Fob

The key fob for your 2018 Mazda is more than just a key; it’s a sophisticated piece of technology that allows you to lock, unlock, and even start your car remotely. Understanding its components, including the battery, is crucial for maintaining its functionality. The battery powers the key fob’s wireless communication with your car. When the battery weakens, you might experience decreased range or intermittent functionality.

Identifying the Correct Mazda 2018 Key Fob Battery

Choosing the correct battery is the first step in a successful replacement. The 2018 Mazda typically uses a CR2025 battery. This small, coin-shaped battery is readily available at most electronics stores, pharmacies, and online retailers. Using the incorrect battery type can damage your key fob, so always double-check the owner’s manual or look for markings on the old battery to confirm the correct type.
