KEY, LOCKS AND ALARM
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.

Remote key 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 illustration is generic - details may vary according to vehicle model.
