I had an interesting discussion with a master. Lock. Smith. About cutting a spare key. For my Tiguan I only need a blade cut. So I can carry it in my wallet. He asked me if my car was one with the proximinity. Keys. I told him no He went on to tell me how easy they were to reposse he then show me the code breakers he had which could open any car. But he said the ones with steering locks were a lot harder to reposse where as once you cracked the I mobilizer and opened the door all he had to do was. Push the start button.
