[VonEverett]

When the key approaches the Audi A6, the doors automatically unlock and the anti-theft alarm is deactivated, accompanied by the turn signals flashing twice. When the key moves away from the Audi A6, the doors automatically lock and the anti-theft alarm is activated, with the turn signals flashing once and the horn sounding briefly.
