Signs Your 2012 BMW 3 Series Key Fob Battery Needs Replacing
Before you start digging around for a replacement battery, let’s make sure that’s actually the problem. Here are some telltale signs that your key fob battery is nearing its end:
- Decreased Range: Are you noticing that you need to be closer to your car for the key fob to work? A dying battery often means weaker signals.
- Intermittent Functioning: Does your key fob sometimes work perfectly and other times barely register? This inconsistency is a strong indicator of a failing battery.
- Warning Messages: Your BMW might display a “Key Fob Battery Low” message on your dashboard, giving you a heads-up that it’s time for a change.
- No Response: This one’s pretty obvious. If your key fob is completely unresponsive, a dead battery is the most likely explanation.
What Type of Battery Does a 2012 BMW 3 Series Key Fob Use?
