Signs Your Key Fob Battery Needs Replacing

- Decreased range: Notice you have to stand closer to your CX-3 for the key fob to work? That’s a classic sign of a weakening battery.
- Intermittent function: Does your CX-3 sometimes respond to your key fob, and sometimes act like it’s not even there? Inconsistent responses are a strong indicator of a battery on its last legs.
- Warning lights and messages: Your CX-3 might be smart enough to tell you directly! Keep an eye out for dashboard warnings related to the key fob battery.
