Reduced Range When Using the Key Fob:
Reduced range when using the key fob indicates a weakening battery. Typically, a functioning key fob should work from a distance of approximately 30 feet. If you find that you must be closer to the vehicle than before, the battery may be about to fail. According to a study by the Automotive Electronics Council (AEC), most key fob batteries last approximately four to five years before beginning to show signs of reduced performance. -
Intermittent Functionality:
Intermittent functionality occurs when the key fob only works sporadically. This often manifests as a need to press the buttons multiple times or experiencing delays in response. A study by researchers at the University of Michigan found that intermittent signals in remote key fobs often correlate with battery drain. If this issue persists, it is advisable to replace the battery as it indicates failing power. -
Flashing LED Light on the Key Fob:
A flashing LED light signifies that the battery is weak or nearing its end. Most key fobs have an LED indicator that lights up when buttons are pressed. If the light flashes dimly or does not illuminate at all, this suggests that the battery power is low. According to key fob manufacturers, consistent flashing usually necessitates battery replacement. -
Difficulty Starting the Car:
Difficulty starting the vehicle indicates potential key fob issues, including battery failure. If the ignition does not recognize the key fob signal, it may be a sign of weak battery power. Research conducted by auto industry experts highlights that often, issues with starting the engine can be traced back to inadequate power supplied by the key fob. -
Key Fob Not Unlocking or Locking Doors Properly:
When the key fob fails to unlock or lock the doors consistently, it suggests that the battery may be drained. This malfunction is bothersome and can hinder access to the vehicle. Automotive safety experts point out that consistent issues with locking or unlocking typically indicate that the key fob battery is on the decline.
Recognizing these signs can help you maintain your Audi A4 2017’s functionality and prevent inconvenience.
