Oh...Stirfry, there is a built in key lock on the roof box. It got painted over too so it's hard to see.
2step: I like the spear idea! Chrome handles might be good as there are no handles on the box as is. If I put them on the "beltline" they could serve as a way to open the top easily. You have to just lift up on the edge of the top to get it to open now.
