Question: Are the locks and keys for these racks included or do I have to order them separately?
Document: That what I am looking for........ Perfect for my Prius. Shipping was very care, no damages. I like it. I would recommended that for anyone who own Prius.
These are sturdy and well built. I recommend following the measurements provided for the placement of the bars. They provide labels for identifying where to place the bars - use them!!! !My only improvement would be that would be the hinge for the over the door frame. I would like it to be attached to the brackets. So when you unlock the bars they release the pressure. The Allen wrenchs would then not be needed.
Well built and very sturdy. However it whistles in the wind and the front clamps don't fit as well as the rear. The clips are lifting the seals away from the door frame and may lead to leaks if caught in rain.
Answer: no
