A key choice
The S4 comes with a choice of two keys: the remote control key (standard) or the advanced key (optional).
The remote control key – convenient and practical
- Locks and unlocks the doors, windows, luggage compartment and tank filler flap at the press of a button
- Locks and unlocks the boot separately
- Remembers customised driver settings for up to four users
The advanced key – the key you can keep in your pocket
The optional advanced key allows you to keep the key in your pocket all the time. The doors unlock automatically when you approach the car and you can start the engine simply by pressing the start/stop button in the centre console.
