Our successful laser track key simulator set of the 1st Generation has been refined to work on the latest series ! It now comes with a special car tension tool (Article 3438). The advantage of the newly adjusted series is that it allows you to work even more effectively using the tensioner. Also the cylinder can be kept in tension when changing the simulator. In addition, the applied tension allows you to work more successfully and contributes to a much longer life span of the individual simulator keys.
