I am an ASE certified technician working in a shop. We have many trucks that can be lifted and other vehicles with lugnuts that require keys. With this kit I can just take what I need and remove the wheels instead of trying to search the car for a key. I had no problems with this kit or removing the wheels. It just saves me a lot of time. Some of the other posters were angry because they didn't fit their locks. When you have real locks with a very, very unique key, no other set will help you other than the exact key for the exact set.
