BitLocker Recovery Key Not Found: How to Find It in Windows 11/10
Seeing the BitLocker recovery key not found message can be worrying, especially when Windows is asking for a 48-digit recovery key before allowing you to access your computer or files. BitLocker is a Windows security feature that encrypts a drive and can request a recovery key when it detects a hardware, firmware, or other security-related change.
The important thing to understand is that the recovery key is not the same as your Windows password, PIN, or product key. Microsoft says the BitLocker recovery key is a unique 48-digit number, and Microsoft Support cannot retrieve or recreate a lost key.
If you cannot find your key, do not immediately reset or reinstall Windows. First, work through the recovery locations below. One of them may contain the key you need.
Let’s learn in detail!
BitLocker Recovery Key Not Found

If your BitLocker recovery key is not found, first note the Recovery Key ID shown on the BitLocker screen. Then, using another device, sign in to the Microsoft account associated with the PC and check your BitLocker recovery keys at Microsoft’s recovery-key page. If the PC belongs to a school or workplace, check the organization’s account or contact IT. You can also check a printed key or USB flash drive where the recovery key may have been saved. If the key cannot be found anywhere, Microsoft cannot recreate it, and resetting the PC may be necessary, which can result in data loss.
Let’s explore the steps in detail!
Step 1: Write Down the BitLocker Recovery Key ID
Before searching for the recovery key, look carefully at the BitLocker recovery screen on your computer.
You should see information about the recovery process along with a Recovery Key ID. Write down the first eight characters or digits of this ID exactly as displayed.
Do not confuse the Recovery Key ID with the actual recovery key. The ID is only used to identify which recovery key belongs to your computer. The actual BitLocker recovery key is a 48-digit number.
If you have more than one recovery key stored in your Microsoft account, the Recovery Key ID makes it much easier to select the correct one.
Take a photograph of the screen with your phone if necessary. This is particularly useful if you need to use another computer or smartphone to search for the key.
Step 2: Check Your Microsoft Account
The first place you should check is your Microsoft account.
This is especially important if you normally sign in to Windows using a Microsoft account. Windows Device Encryption can automatically associate a recovery key with the Microsoft account used during device setup.
Using another computer, tablet, or smartphone, open a web browser and visit Microsoft’s BitLocker recovery key page:
Microsoft BitLocker Recovery Key Page
Sign in using the same Microsoft account that was used on the locked computer.
After signing in, look through the listed recovery keys. Compare the Recovery Key ID shown online with the first eight characters or digits you wrote down from the BitLocker screen.
When the IDs match, use the corresponding 48-digit recovery key on your locked computer.
If you see several keys, do not randomly enter them. Match the Recovery Key ID first. This helps prevent confusion between an older key and the key associated with your current BitLocker-protected drive.
Step 3: Try Other Microsoft Accounts You Have Used
If you do not see the key in the Microsoft account you initially expected, think about whether someone else originally set up the computer.
For example, a family member, previous owner, or another person may have used their Microsoft account during Windows setup or when encryption was enabled.
Microsoft specifically notes that if somebody else set up the device or enabled BitLocker, the recovery key may be stored in that person’s Microsoft account.
Ask that person to sign in to their Microsoft account and check the BitLocker recovery-key page.
If the computer was purchased second-hand, contact the previous owner if possible. However, do not ask for their Microsoft account password. You only need the appropriate BitLocker recovery key associated with your device.
Step 4: Check Your Work or School Account
If the computer has ever been connected to a work or school organization, the recovery key may have been saved by that organization.
This commonly applies to company-owned or school-managed computers. Organizations can manage BitLocker recovery information through their administrative systems.
From another device, visit:
Microsoft Work or School BitLocker Recovery Page
Sign in using your work or school account.
Depending on how your organization manages the device, you may be able to select your device, open its information, and view the available BitLocker keys.
If you cannot access the recovery key yourself, contact your organization’s IT department. Microsoft recommends contacting IT when a managed device’s recovery key is controlled by the organization.
Step 5: Look for a Printed BitLocker Recovery Key
If the online search does not work, check whether you printed the recovery key when BitLocker was enabled.
Look through important computer documents, folders, files, or paperwork that you normally keep for your PC.
A printed recovery key generally contains the 48-digit recovery number and information that can help identify the associated key.
If you find several printed recovery keys, compare their Recovery Key IDs with the ID displayed on your computer.
Do not assume that the newest-looking document is automatically the correct one. The ID is the better way to identify the required key.
Microsoft lists a printed copy as one of the possible places where users may have saved their BitLocker recovery key.
Step 6: Check Your USB Flash Drives
Another possibility is that you previously saved the recovery key to a USB flash drive.
Think about whether you used a USB drive when BitLocker was originally configured.
If the recovery key was saved as a text file, you can connect the USB drive to another computer and open the file using Notepad or another text editor.
If the BitLocker recovery screen allows you to use a USB recovery key, follow the instructions shown on the screen.
Be careful when checking USB drives. Do not format or erase a drive simply because you cannot immediately see the recovery-key file.
Microsoft identifies a USB flash drive as another possible location for a saved BitLocker recovery key.
Step 7: Check Files and Backups Where You May Have Saved the Key
If you previously backed up your BitLocker recovery information, search your personal files for documents containing terms such as BitLocker, Recovery Key, or Recovery Key ID.
You may have saved the key as a text file, printed it, or stored it in another secure location.
If you use cloud storage for personal documents, check your relevant folders from another device. Microsoft also recommends keeping additional copies of a recovery key in secure locations.
Remember that the recovery key itself is sensitive. Anyone who obtains the correct key may potentially use it to unlock the encrypted drive, so do not post it publicly or send it to strangers.
Step 8: Think About Recent Hardware or Firmware Changes
If Windows suddenly started requesting a BitLocker recovery key, think about what changed immediately before the problem appeared.
BitLocker can request recovery information when it detects a possible security issue or certain hardware, firmware, or software changes.
For example, the prompt might appear after a significant hardware change or another change that affects the system’s trusted startup environment.
If you know exactly what change caused the prompt, reversing that change may sometimes help. However, do not start randomly changing BIOS, UEFI, Secure Boot, TPM, or boot settings if you are unfamiliar with them.
Changing additional security settings without understanding them can make troubleshooting more complicated.
The safest approach is to locate the correct recovery key first.
Step 9: Do Not Confuse the Recovery Key With Your Windows Password
A common mistake is entering your Windows PIN or password when BitLocker is asking for a recovery key.
These are different things.
Your Windows password or PIN normally helps you sign in to Windows. The BitLocker recovery key is a separate 48-digit number used to unlock an encrypted drive when BitLocker enters recovery mode.
Similarly, your Windows product key is not your BitLocker recovery key. A Windows product key is generally a 25-character activation code, while a BitLocker recovery key is a 48-digit number.
Entering the wrong type of key will not solve the BitLocker recovery screen.
Step 10: Contact Your Organization or Manufacturer When Appropriate
If the computer belongs to a company, school, or another organization, contact the organization’s IT administrator before attempting a reset.
The organization may have automatically backed up the recovery key and may be able to retrieve it for you.
If the computer is your personal device and you have exhausted all recovery-key locations, you can contact the computer manufacturer for general hardware or recovery guidance.
However, do not expect the manufacturer or Microsoft Support to generate a replacement BitLocker recovery key. Microsoft states that it cannot retrieve, provide, or recreate a lost BitLocker recovery key.
Step 11: Consider Windows Recovery or Reset Only as a Last Resort
If you cannot find the recovery key and cannot undo whatever caused BitLocker recovery to activate, you may eventually need to use Windows recovery options.
This is where you need to be especially careful.
Microsoft states that if the BitLocker recovery key cannot be found, resetting the device may be necessary, and resetting can remove files depending on the selected option.
Do not choose Remove everything simply because you are frustrated with the BitLocker screen.
If important files are stored on the encrypted drive and you do not have the recovery key, resetting the computer should be treated as a last resort. Carefully review the available recovery choices before proceeding.
