Problem:

BMW BDC3 key cloning usingKeydiy KD-X4definitely key is Hungary. Failed with errors code B7 I have tried both laptop and cellphone. Is this key locked (encrypted) ?

Possible reasons:

1). Keydiy cannot copy all BDC3 Hungary keys. Only 90% success rate. Still some models are not supported.

2). The date on the key is before 2020, it can’t be copied.

Better read vehicle information first to verify if it is BDC2 or BDC3 system.
