Hi Bill,
Since your Thule Evo Flush Rail feet currently just have the black plastic plugs installed, you'll need the Thule One Key System, Part # TH450400. This kit includes four lock cylinders and two matching keys, so you'll have everything you need to replace the plugs and lock all four feet with a single key.
By the way, what are you planning to carry on the rack most of the time, bikes, skis, or a cargo box?
