Owning a 2017 Mazda means enjoying a sleek ride and innovative technology, including your key fob. But even the most advanced tech needs a little juice to run. If your Mazda key fob is acting up – locking and unlocking intermittently or failing to start your car – a dead battery might be the culprit. This article guides you through everything you need to know about your 2017 Mazda key fob battery, from identifying the correct size to replacing it yourself.
Understanding Your 2017 Mazda Key Fob
Before popping open your key fob, it’s crucial to identify the battery type it uses. Most 2017 Mazda models, including the Mazda3, Mazda6, CX-3, CX-5, and Miata, utilize a CR2032 battery for their key fobs.

Ignoring a fading key fob battery only leads to frustration down the road. Here are some telltale signs that it’s time for a replacement:
- Decreased Range: You find yourself standing closer to your Mazda to lock or unlock the doors.
- Intermittent Functioning: The key fob works sometimes but not others, creating a frustrating guessing game.
- Dashboard Warning Light: Your Mazda’s dashboard may display a “Key Fob Battery Low” warning message.
- No Response: The key fob completely fails to respond, leaving you stranded.
