VVDI MB Cannot Read or Renew v51 Key Password with NEC Adapter??

Here comes the problem: why I can read the NEC v51 key with the xhorse vvdi mb adapter without any issues shown in picture but cannot read the password or renew it? Only works with the NEC adapter I have to clip it on?

Tried 2 different v51 keys. Both had the same issue. Could not renew or read password from it.
Receiving “Read failed error – 1004” notification.
