Looking for the best Mercedes key to use with VVDI MB Tool Programmer?
You need to buy new virgin oem keys which are not available to my understanding and are one time use only.
You can buy Xhorse BE Keys for best quality or any aftermarket BE keys both will work but Xhorse are better quality and logic. If you are using VVDI MB tool Xhorse keys will bring you 200 points from each key which you can use to exchange for token and I tested the frequency can be changed through software or with resistance!
Look at the following table, it includes all Mercedes Benz keys from xhorsevvdi.com to use with VVDI MB tool.
