Yanhua ACDP2 BMW BDC2 Read Key Info Error Solution

Problem:

Tried to add a spare smart key to BMW G series BDC2 system with Yanhua ACDP2 and module 38. But ACDP cannot detect new key (Autel BMW ikey) to be added. Any idea?

Solution:

For Yanhua ACDP BMW BDC3 function, use original BMW BDC3 key only.

Autel ikey works with Autel devices only.
