Thieves utilize 2 devices to magnify the signal from a key fob located inside a house, fooling the car into thinking the owner is standing right next to it with the key.

To avoid this, Audi owners can:

• Use a Faraday Pouch: These signal-blocking sleeves prevent the fob from transmitting its ID when not in usage.
• Store Keys Wisely: Avoid leaving key fobs near the front door or windows of a home.
• Disable Keyless Entry: Some more recent Audi designs allow owners to briefly disable the distance function via the MMI settings.

Fixing Common Audi Key Issues

If a key fob quits working unexpectedly, it may not constantly be the battery.

• Signal Interference: Large metal items, cell phones, or radio towers can hinder the fob's signal.
• De-synchronization: Occasionally, if the battery is dead for an extended period, the fob might lose its sync with the car. This often needs a professional reset.
• Faulty Keyless Entry Sensors: If the buttons on the fob work but the door deals with don't, the issue may lie with the sensing units inside the car door rather than the fob itself.
