Bit Locker

Question

Bit Locker has me locked out of my computer! How do I get back in?

Answer 1

To get back into a BitLocker-locked computer, a valid BitLocker recovery key is required. Without it, the drive cannot be unlocked and the data cannot be accessed.

Use these steps in order:

1. On the blue BitLocker recovery screen, enter the 48‑digit BitLocker Recovery Key exactly as shown (hyphens are optional). If the key is correct, Windows will start normally.
2. If the key is not already available, check all possible locations where it might have been saved:
   • Microsoft account (for personal/home devices): sign in at https://myaccount.microsoft.com, go to Devices, select the affected Windows device, and choose View BitLocker Keys.
   • Work or school account: recovery keys may be stored in Microsoft Entra ID or in on-premises Active Directory; contact the organization’s IT/helpdesk to retrieve the key.
   • Printed copy or written note kept with personal records.
   • USB flash drive where the recovery key or recovery password file was saved.
3. If the recovery key is found, enter the 48‑digit recovery password on the BitLocker recovery screen to unlock the device.
4. After successfully signing in, determine why BitLocker went into recovery (for example, too many wrong PIN attempts, firmware/BIOS changes, or hardware changes) and fix the root cause so it does not happen on every restart. If a PIN was forgotten, reset it from the BitLocker Control Panel after unlocking with the recovery key.

If the recovery key cannot be found in any of the supported locations, the key cannot be recreated or bypassed by anyone, including Microsoft support. In that case, the only option is to erase/reinstall Windows on the drive, which results in loss of the encrypted data.

Answer 2

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.

(Note, even if your device does not show on the Microsoft account, the Bitlocker Recovery Key may still be available on this link)

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 will 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.
