Windows 10: Surface Go locked out by Bitlocker

Hi

I have been locked out of my Surface Go by Bitlocker. I know my Bitlocker key, but the next screen asks for an admin password that I don't have. I have tried my Microsoft password, but it isn't this. When I hit the 'forgotten your password' option, it just sends me right back to the beginning again.

I can't get access to any of my work. This is really having a dreadful affect.

Has anybody got any ideas about how to get past this?

Thanks

:)

 

problem with bitlocker

Hi Roeslie,

Thank you for writing to Microsoft Community Forums.

We need some more details to help you find the solution to your problem.

• Which edition of Windows 10 is installed on your surface machine?
  
• Did you notice any changes on the computer recently?
  
• When you say, you have a problem with your Surface machine about BitLocker key, do you mean that the surface machine asks you to enter the BitLocker key to allow you to sign into Windows?
  
• Does the other computer ask you to enter the BitLocker key to allow you to access the files saved on it?
  

If you are being asked to enter a BitLocker key to sign into your surface machine and you don’t remember your BitLocker key, you can follow the instructions given in the link below to find the BitLocker recovery key.

Bitlocker has locked me out of windows during doing a full reset on surface book.

Bitlocker has locked me out of windows during doing a full reset. Don't have keycode or access to any windows directory including being prevented from doing full factory reset because it appears that the volume where the instalation copy of windows is stored,
seems to be 'Volume 3', is the only volume listed twice over, and both are locked by bitlocker. The system is a surface book with windows 10.

How do I work around this to do a full factory reset?

 

BitLocker on Surface Pro 3 not working correctly

Hi JulianSchubert,

Thank you for posting your question in the Microsoft Community

TPM will lock itself out after a few incorrect authentication attempts. These could be due to incorrect PIN entry for BitLocker or incorrect PIN entry for TPM virtual smartcard PIN. For TPM version 1.2, the lockout behavior depends
on individual TPM manufacturer. For TPM 2.0, the specification states that the TPM will enter lockout after 32 incorrect attempts.

To terminate this BitLocker recovery loop, you need to suspend BitLocker within WinRE, I suggest you to follow the below steps.

Step 1:

1. Choose the “Skip this drive” link at the bottom of the page where you are asked to enter the recovery key. You should be presented with a menu that will let you get to a command prompt (The sequence is Advanced
   options -> Troubleshoot -> Advanced options -> Command prompt).
   
2. Once you have a command prompt,
   use the following command to check the BitLocker status of the C: drive:
   manage-bde -status c:
   
3. If the status is returned as locked, you’ll need to use the following command to unlock it using your recovery password:
   manage-bde -unlock c: -rp <your 48-digit recovery password>
   
4. Once the drive is unlocked you'll need to use the following command to suspend protection:
   manage-bde -protectors -disable c:
   
5. Then exit and reboot. The computer should now successfully boot Windows. Once there, use the BitLocker control panel to resume BitLocker protection.
   
6. You can reset TPM lockout using
   tpm.msc
   

Note: The recovery loop can occur for other reasons such as cases where TPM is disabled or malfunctions. You can still use the above steps to suspend BitLocker and boot Windows in such cases

Hope it helps.
