Have three bike carriers ordered at the same time. This had different keys - of course I do not want to use multiple keys to a car. The dealer was unable to provide me with the same locks because Thule supplies the items unsorted and the code number is on the package probably not recognizable. The instructions for assembling can be improved. In particular, the images are so small that hardly anything can be recognized. The carrier is easy to mount on the roof. However, one must be very careful that dangling strap will not scratch the roof. In the degraded condition are parts without rights, one must be careful in the basement so that nothing is lost.
