Go to "Advance" >> Command Prompt >> input command: Manage-bde -unlock C: -rp 48 digitals

also pop "failed to unlock with this recover key".

the key is stored in AD and Password ID is same

Answer 1

Hello there,

Your recovery key does not work for some reason and you already checked that the key ID in AD is matching the requested key ID.

Firstly, make sure your environment meet the following conditions:

The domain must be configured to store BitLocker recovery information.
The computers protected by BitLocker must be joined to the domain.
BitLocker Drive Encryption must have been enabled on the computers.
