Dead Key Fob or Dying Battery? Spotting the Signs

It can be frustrating when your key fob suddenly stops working. But how can you tell if it’s simply a dead battery or a more serious issue? Here are a few telltale signs:

• Decreased Range: Noticing you need to be closer to your car for the key fob to unlock it? This reduced signal strength is often an early indicator of a weakening battery.
• Intermittent Functionality: Is your key fob working sporadically? One minute it’s fine, the next it’s unresponsive. This inconsistency usually points towards a battery on its last legs.
• Dashboard Warning: Some BMW models display a “Key Fob Battery Low” warning on the dashboard, providing a clear sign it’s time for a replacement.
• Physical Damage: While less common, physical damage to your key fob, like cracks or water exposure, can impact battery performance and require professional attention.
