The soft leather tonneau cover doesn't lock. There's a hard plastic piece that sits between the bars and the cab. The tonneau cover comes up and velcroes around the bars. Attached to the Baja with screws on the top of the sides and top of the tailgate is a metal bracket thing. The cover has a hard rubber material sewn into the cover. You stretch the cover over the bracket, and the hard rubber (which goes around the entire perimeter of the cover) comes down and hooks onto the brackets. If I had a digicam, I'd take pics, but the fiancee has that, and with our work schedules and lack of a joint house at this point, it's getting tough to see her, let alone use that time to take pics of my car/truck/suv thing. I'll see if I can do something this week or weekend, but it's doubtful.
