  • Hi,

    Have you tried manage –bde tools?

    You can try to unlock a BitLocker-protected drive by using a recovery password or a recovery key.

    The following example illustrates using the -unlock command to unlock drive E with a recovery key file that has been saved to a backup folder on another drive.

    manage-bde –unlock E: -recoverykey "F:\Backupkeys\recoverykey.bek"

    For more information, please refer to the link:

    Manage-bde: unlock
