Why is My Honda Civic Key Fob Not Working?
Before we jump into battery replacement, it’s helpful to understand why your key fob might be acting up. Here are the telltale signs of a failing key fob battery:
- Decreased Range: You find yourself standing closer and closer to your car to lock or unlock it.
- Intermittent Functioning: The key fob works sometimes, but not always, leading to frustrating inconsistencies.
- Dashboard Warning: Some Honda Civics might display a “Key Fob Battery Low” warning on the dashboard.
- Slow Response Time: There’s a noticeable delay between pressing a button on your key fob and the car’s response.
If you’re experiencing any of these issues, a dying key fob battery is likely the problem.
What Kind of Battery Does a 2012 Honda Civic Key Fob Take?
Your 2012 Honda Civic key fob uses a CR2032 battery, a common type of lithium coin battery. You can easily find these batteries at most hardware stores, automotive stores, and online retailers.
