One New OEM key blank for a 2010-2011 Ford Explorer Sport Trac. This key blank says 'Ford' on one side of the black plastic key bow or head and is blank on the other side. This is a regular key and not a transponder key. Some Ford vehicles within the same year may have an optional transponder system and require a transponder key. You can quickly find out if your vehicle has a transponder system by calling your dealership and providing them with the vehicle VIN.
