Remote control key, on left, and button-less key (Key Tag)*, on right.

The remote control key is not physically used when starting since the car is equipped with support for keyless starting (Passive Start) as standard. The key must be in the front part of the passenger compartment, e.g. in the driver's pocket or the runnel console cup holder, for it to be possible to start the car.

Keyless locking and unlocking of doors, boot lid (Passive Entry*) is also available as an option. The key then has a range extending in a semicircle with a radius of approx. 1.5 metres (5 feet) out from the driver's door and approx. 1 metre (3 feet) out from the boot lid respectively.

With keyless starting and keyless locking and unlocking, the remote control key can be located anywhere in the passenger compartment or the cargo area and maintain the functionality to start the car.

Each one of the remote control keys included with the car can be linked to a driver profile with unique settings for the car. When a key with a certain profile is used, the car's settings are adapted according to the profile.

Button-less key (Key Tag)

For cars equipped with keyless locking and unlocking*, a slightly smaller, lighter and button-less key (Key Tag) is supplied. It works the same way as the normal remote control key when it comes to keyless starting and locking and unlocking1. It has no detachable key blade and the battery cannot be replaced.

Be aware of the risk of locking the remote control key/Key Tag in the car.

A remote control key/Key Tag left in the car will be deactivated when the car is locked and the alarm is armed using another valid key. The "Double lock" function is also deactivated.

The deactivated key is reactivated when the car is unlocked.


Remote control key functions for keyless starting and keyless locking and unlocking* can be disrupted by electromagnetic fields and screening.


Avoid storing the remote control key close to metal objects or electronic apparatus, e.g. mobile phones, tablets, laptops or chargers - preferably no closer than 10-15 cm (4-6 inches).

If there is still interference - use the remote control key's detachable key blade to unlock and then place the key in the backup reader in the cup holder to disarm the car.


When the remote control key is placed in the cup holder, make sure that no other car keys, metal objects or electronic apparatus (e.g. mobile phones, tablets, laptops or chargers) are in the cup holder. Several car keys close to each other in the cup holder can cause interference with each other.
