Yanhua ACDP2 Not Obtain Authorization A501?

Problem:

I was trying to add a new spare key to BMW F series BDC by OBD, but Yanhua mini acdp2 said i don’t have authorization for A501 module?

A501 authorization comes with module 31.

To program BMW BDC key or reset mileage via OBD, need to purchase module 31 A501 license.
