I work for a dealership and whenever we need Key replacements for roof racks I get them from this Seller. Ill argue to say it even better than my wireless g pro & viper ultimate. One thing I will say is that it could be a TINY bit more "heavy duty". Cant flip it and reverse feature is used often. Could have had slightly better instructions to explain the orientation of the rail guides. Not sure how long it will last but it solves my immediate problem. ITS LITERALLY THE SAME! Not only did it hold me, but placing weight on the bars seemed to solve the wobble problem. Out came the drill and the tape measure, pencil behind his ear, looking the part. When i first used them they served their base purpose.
