How do I activate the keyless entry feature on my Audi A6?

I just purchased an Audi A6 and I can't figure out how to use the keyless entry feature. Can someone provide a step-by-step guide on how to activate it?

To activate the keyless entry feature on your Audi A6, first ensure that the key fob is in your possession. Then, simply walk towards the car and it will automatically unlock when it detects the presence of the key fob.

You can also activate the keyless entry feature from a short distance away, by pressing and holding the unlock button on the key fob for a couple of seconds. This will unlock all the doors and the trunk as well.

If you're having trouble getting the keyless entry feature to work, try replacing the battery in your key fob. Sometimes a weak battery can prevent it from connecting with the car.
