Introduction to the topic  
If you sell the vehicle, you will not be able to transfer any  
mobile keys already installed on it to the buyer. In this  
case, delete all mobile keys ÿ p. 213, Indications for use. If you  
lend or sell the vehicle, inform the user or buyer that the vehicle  
has mobile keys.  
The function “mobile phone as vehicle key” in combination with  
the Volkswagen We Connect app is called a mobile key.  
This allows the use of a suitable mobile phone device instead  
of a conventional vehicle key. With the active mobile key it is  
possible to lock and unlock the vehicle and start the engine. For  
these operations it is not necessary for the vehicle or the mobile  
phone device to be connected to the Internet.  
The vehicle can be locked with mobile keys, even if there  
is an ignition key belonging to the vehicle inside.  
The vehicle is supplied from the factory with the “Mobile Key”  
function disabled. This would also be the state when the  
infotainment is reset to factory settings. In order to activate the  
function, you will first need to install and activate one or more  
mobile keys. You will need a suitable mobile phone device for  
this, on which the Volkswagen We Connect app must be installed
