How to activate the keyless entry function for Audi A6L?

[DelElliott]

When the key approaches the Audi, the doors automatically unlock and the anti-theft alarm is deactivated, while the turn signals flash twice. When the key moves 3-5 meters away from the Audi A6, the doors automatically lock and the anti-theft alarm is activated. When remotely locked, the doors are secured, the turn signal flashes once, the horn sounds once, and the vehicle enters anti-theft alarm mode.
