Autel MaxiIM KM100 Key Programmer can successfully program 2007 BMW 323i all keys lost via OBD. It worked for this particular CAS3 because it wasn’t encrypted. Below I will show how to do it.

Procedures:

Plug MaxiVCI V200 into OBD,
Make sure network connection is good during process.
When I was performing key add or all keys lost, KM100 failed and said:”Current key is locked, please check that a new key is inserted.”
So I should unlock the key at first.
