A BitLocker recovery key cannot be retrieved or recreated by Microsoft Support.
Use the recovery key ID to match the correct key in one of these locations:
- Microsoft account
- On another device, open https://aka.ms/myrecoverykey
- Sign in with the Microsoft account associated with the device
- Find the recovery key that matches the key ID and use it to unlock the drive
- Work or school account
- If the device was ever signed in with a work or school account, open https://aka.ms/aadrecoverykey
- Sign in, select Devices, expand the device, and select View BitLocker Keys
- Match the key ID and use that recovery key
- Printed copy
- Check any papers printed when BitLocker was turned on
- USB flash drive
- If the key was saved to USB, connect it and follow the prompts, or read the text file from another device
- If the device is managed by an organization
- Contact the IT department to retrieve the recovery key
If the recovery key cannot be found, the remaining supported option is to reset the device using Windows recovery options. This removes all files.
