Bit locker recovery key

Question

I can’t get into my computer and can’t find the bit locker key

Answer 1

If your drive is encrypted with Bitlocker, the only place the Bitlocker Recovery key is automatically stored is on the associated Microsoft account on the link below, be sure to check any Microsoft account that may have been used on the PC and also any work or school account that may be linked to the PC.

Are you able to find the Bitlocker Recovery Key on any account that may have been used or linked to the laptop?

If not, do you have a safe backup of your files, or use a cloud service like OneDrive to sync your files online.

If you are unable to find the Bitlocker Recovery Key on any account that may have been used on that device, then I am sorry for the bad news, a Windows reset does not work on an encrypted drive, the only way to access that device is to create a bootable Windows 11 USB on another working PC and use that to clean install Windows and at the start of the installation, delete all partitions on the drive to remove the encryption, which will sadly result in loss of all data on the drive.

Answer 2

BitLocker encryption can’t be bypassed. Access to the PC requires the 48‑digit BitLocker recovery key. If the key can’t be found in any of the supported locations, the only option is to reset the device, which erases all data on the encrypted drive.

Use these steps to try to locate the key:

1. Note the Recovery Key ID
   • On the blue BitLocker screen, write down the first 8 digits of the recovery key ID. This helps match the correct key if multiple keys exist.
2. Check personal Microsoft account
   • From another device, open a browser and go to https://aka.ms/myrecoverykey.
   • Sign in with the Microsoft account that might have been used on the locked PC.
   • Look for a key whose Key ID matches the one shown on the BitLocker screen and use that 48‑digit key to unlock.
3. Check work or school account / Intune
   • If the device was ever joined to an organization (work or school):
     • Go to https://aka.ms/aadrecoverykey and sign in with the work/school account, then go to Devices → select the device → View BitLocker Keys.
     • Or, if the device is Intune‑enrolled, sign in to the Company Portal website → Devices → select the locked PC → Get recovery key → Show recovery key.
4. Check other backup locations
   • Printed copy: Look for any printout labeled “BitLocker recovery key.”
   • USB flash drive: Insert any USB drive that might contain the key into another PC and look for a .txt file with the recovery key.
   • Microsoft Entra ID / Active Directory (for organization‑managed devices): Contact the organization’s IT/helpdesk to retrieve the key.
5. If the key cannot be found
   • If none of the above locations contain the key, the recovery key cannot be recreated by anyone, including Microsoft Support. BitLocker is designed this way to protect data.
   • The only remaining option is to reset or clean‑install Windows using the available Windows recovery options. This will remove all files on the encrypted drive.

For future protection, when BitLocker is turned on again, ensure the recovery key is backed up to a Microsoft account, work/school account, or printed/USB copy stored safely.
