If the recovery key is not shown for any Microsoft account associated with the device, there is no supported way to bypass BitLocker or recreate the missing key. Microsoft Support also can’t retrieve, provide, or recreate a lost BitLocker recovery key.
Next steps:
- Check every possible place the key may have been saved:
- Another Microsoft account that may have been used when the device was first set up.
- A work or school account, if the device was ever connected to one.
- A USB drive, printed copy, text file, PDF, backup folder, or cloud storage.
- Match the Key ID shown on the BitLocker screen with the first 8 characters of any stored key.
- If the device was ever managed by work or school, contact the organization’s IT administrator. Recovery keys can be stored in Microsoft Entra ID, AD DS, MBAM, Intune, or Configuration Manager BitLocker Management.
- If the Surface started asking for the key after a UEFI or TPM firmware update, and the correct recovery key is available, the documented recovery path is:
- Create a Surface recovery USB from another computer.
- Boot the Surface from that USB.
- Go to Troubleshoot > Advanced Options > Command Prompt.
- Run:
manage-bde.exe -unlock -recoverypassword <Password> <DriveLetter>: manage-bde.exe -protectors -disable <DriveLetter>: - Restart and enter the recovery password again.
- If Windows still does not start but the correct recovery key is available, the drive can be unlocked from the recovery environment and data can be copied off with
copyorxcopybefore resetting the device. - If the recovery key cannot be found anywhere, the remaining option is to reset or reinstall Windows by using a Surface recovery image. Warning: this removes the existing data on the drive.
For a personal Surface device, support options listed include using the Surface app or Get Help. For a work or school device, contact the organization’s IT helpdesk or admin.
