Top Tools to Program BMW BDC Key by OBD

 Yanhua ACDP, Autel and Xhorse released BMW F series BDC immobilizer key programming via OBD recently.

NOTE: This update is for BDC only. It will not work with FEM.

At the moment only some BDC are supported. 085 version is not supported (need pre-processing).

 

 

Autel IM508/IM608 Pro/IM608 II

Autel released this for free.

For example: Mini Countryman 2019 model – it read data first and has you make a save of it. Then it will go into pre-processing and let’s you add a key or disable / remove keys. It worked by OBD.

Yanhua Mini ACDP1/ACDP2

085 version is not supported either. Need to do pre-processing with module 2.

Is it safe to program BMW BDC Key via OBD?

ONLY BDC has a gap in the system that is why they are doing it – the BDC is already fixed and there is no mistake.

You can unlock BDC by OBD if versions are supported.

Before proceeding make a backup of the original information and not regret a bad procedure.

Better take out the BDC to make backup and program key on the bench.

Bench is not 100% safe either if it has a clip read going wrong.
