• Use a Faraday Pouch: These signal-blocking sleeves avoid the fob from sending its ID when not in usage.
• Shop Keys Wisely: Avoid leaving key fobs near the front door or windows of a home.
• Disable Keyless Entry: Some more recent Audi designs permit owners to temporarily disable the proximity function by means of the MMI settings.

Repairing Common Audi Key Issues

If a key fob stops working suddenly, it might not always be the battery.

• Signal Interference: Large metal objects, cellular phone, or radio towers can disrupt the fob's signal.
• De-synchronization: Occasionally, if the battery is dead for a long duration, the fob may lose its sync with the car. This frequently requires a professional reset.
