Remote key

The remote key is used to lock and unlock doors, the tailgate and the fuel filler door. The remote key must be in the vehicle in order to start the engine.

16w17 - SPA - Remote Keys overview both variants
Remote key1 and button-less key (Key Tag)*.

The remote key is not physically used to start the ignition because the vehicle is standard-equipped with keyless start (Passive Start). The key only needs to be in the front section of the passenger compartment.

For vehicles equipped with keyless locking and unlocking (Passive Entry)*, the engine can be started with the key anywhere in the vehicle. A smaller, lighter and button-less key (Key Tag) is also provided.

The remote keys can be linked to different driver profiles to store personal settings in the vehicle.


The remote key contains a button cell battery. Keep new and used batteries out of the reach of children. If batteries are swallowed, they can cause serious injury.

If any damage is detected, e.g. if the battery cover cannot be closed properly, do not use the product. Keep defective products out of the reach of children.

Be aware of the risk of locking the remote key in the vehicle.

  • If the remote key or key tag is left in the vehicle, it will be deactivated when the vehicle is locked and the alarm set using another valid key. The key will be reactivated when the vehicle is unlocked.

Button-less key (Key Tag)*

The button-less key2 provided with the keyless locking and unlocking function works in the same way as the regular remote key for keyless start, locking and unlocking. The key is waterproof up to a depth of approx. 10 meters (30 feet) for up to 60 minutes. It does not have a detachable key blade and its battery cannot be replaced.


Electromagnetic fields or obstructing objects may interfere with the remote key's functions for keyless start and keyless locking and unlocking*.


Avoid storing the remote key near metal objects or electronic devices, e.g. cell phones, tablets, laptops or chargers – preferably no closer than 10-15 cm (4-6 in.).

If you experience interference, use the remote key's detachable blade to unlock the vehicle and then place the remote key in the backup reader in the tunnel console storage compartment to disarm the alarm and start the vehicle.


When the remote key is placed in the backup reader in the storage compartment, make sure that no other vehicle keys, metal objects or electronic devices (e.g. cellular phones, tablets, laptops or chargers) are also placed there. Multiple vehicle keys close to each other in the storage compartment can disrupt their functionality.
