The Replacement Key for Thule Racks and Carriers # THKEYN3021 is the correct replacement key need for your Sears X-Cargo 3021 Carrier per the manufacturer.
If you need the whole lock with key The Replacement Lock Core and Key for SportRack Explorer Cargo Box # SR03807 will work for you per the manufacturer as long as your current lock resembles this one.
