Auto lock may be available depending on your car's build date but you should be warned that if you ever go to a car wash you better have another key with you if you have this added. The car may roll through the tunnel at a speed which will trigger the auto-lock since the key must be on for the car to be in Neutral and with the key on the feature is active.

The auto lock feature has caused a many a distressful visit to a carwash on the vehicles so equipped.
