Unknown Bitlocker Key

[Philip Shaw]

Good afternoon. I just got a call from a potential customer who has a Dell Optiplex 3050 that is set up as an imaging server. They had a power surge and it took out the power supply. They replaced the power supply and now it asks for a Bitlocker key. They have no clue what the key is and neither does the company that set it up. I told her where to look in her Microsoft account and the key is nowhere to be found. Since it is the original drive in the original computer is there any way to get the computer to recognize the Bitlocker key? Any other suggestions?

Thanks.

Or someone chosen and setup a password

or it is a transparent bitlocker pre activation

I bet someone entered a password without paying enough attention

otherwise it is linked with a Microsoft/Outlook/MSN account and it is matter of searching in the correct one.

Obviously it can also be linked to the self hardware so first of all this should be managed on the original computer

Only a really low percentage of possibilities is that this is what said above. You can discover that only pluggin' the drive to the DE.

If it asks you just an unlock confirmation, it is the first stage of the encryption

if it prompts for the three options (password, key and I right now I forget the third one) you'll have the confirmation that despite what the customer says, he/she/they had entered a password or the login is linked to a Microsoft account

 It sounds like you're dealing with a "modern standby" or "automatic device encryption" issue, which is common with Dells. When the power supply failed and was replaced, the TPM (Trusted Platform Module) likely detected a change in the power state or hardware environment, triggering a security lockout. 

  Some situations the data can be decrypted with recovery tools as the drive sometimes is just in a "suspended" state, however, the system would need to be reinstalled if it needs to log back into the OS as without the recovery key, there is no way to "decrypt it" via Windows.

 Sometimes, the Dell BIOS will prompt for the BitLocker key because it has defaulted to RAID On instead of AHCI (or vice versa) after a power loss, you can check this setting.

Hi Philip, how are you?

Did you have any success with this case?
I had two similar cases where, unfortunately, I wasn't successful. I hope you have better luck with yours. If you could, please share the status of your request and how you managed to overcome this problem. Thank you.

Because it’s the same original drive in the same Dell OptiPlex 3050, the most likely issue is that the power surge or PSU replacement changed/reset TPM or BIOS settings, which triggered BitLocker recovery.

BitLocker usually relies on the motherboard’s TPM chip, not just the drive itself. If the TPM state changed, Windows will ask for the 48-digit recovery key.

The best thing to try first is:

• restart and press F2 for BIOS
• make sure TPM Security = Enabled
• TPM On = Enabled
• Secure Boot = Enabled
• confirm boot mode is still UEFI
• do not clear the TPM

If BIOS settings were reset, restoring them may allow it to boot normally.

If the key is not in the customer’s Microsoft account, check whether the machine was set up under:

• the IT company’s Microsoft account
• Active Directory / domain controller
• Microsoft 365 / Entra / Azure device records

For a business imaging server, the recovery key is often stored there instead of a personal Microsoft account.

If the surge damaged the motherboard or TPM, there is no bypass without the recovery key. At that point the options are to recover the key from backups / IT records or wipe and rebuild the server.

IF you want to trust the customer

- mean: he/she says that they didn't setup any password,

AND

IF the customer owns a pro computer

the starting point is the original computer with its original BIOS setup

Then, again, if the first IF is true, the Microsoft account (if any)

It can be tested on DataExtractor in some few cases , it asks if you want to unlock.the drive which appears really locked ... but then it doesn't ask the password/key and it mounts the partition with the unlocked icon 🔓
