4. Is it possible to disable a lost key?
Yes. When a new key is programmed at a dealer, the professional can clean the old key's digital signature from the car's memory, guaranteeing that if someone finds the lost key, it will no longer start the engine.
5. How do I secure my key from "Relay Attacks"?
Relay attacks take place when thieves use a signal booster to "imitate" your key's proximity signal from inside your house. To avoid this, keep your Audi keys in a Faraday pouch or a metal box, which blocks the transmission of radio frequency signals.
