Finding the correct Bitlocker-key

I want to install an unsigned driver. Therefore, I followed all the steps to do an advanced (re)boot of the system, and just before rebooting it asks me for a Bitlocker recovery key. A bit of research showed me that I can find that on my Windows account,
and indeed for this laptop it says that the Bitlocker is enabled. However, when I click on the link that says show recovery key, it only gives me a wrong recovery key (the device has a different name and the key does not have the same ID).

How/where can I find the correct recovery key?

 

BitLocker Recovery key not correct

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues with BitLocker recovery key on your PC. I will certainly try my best to assist you with the issue.



Let’s try disabling secure boot on the PC. Follow the steps mentioned below and check if that helps.

1. Power the device off and then back on.
2. Look for a message on the boot screen just before or after the manufacturer logo appears. You may need to press the F1, F2, or Delete button, whatever key is indicated on the boot screen to enter BIOS Settings.
3. Inside BIOS, look for a tab called BOOT and select that page. Depending on the BIOS manufacturer, this page could be BOOT, ADVANCED, STARTUP, etc.
4. Look for a setting for UEFI Secure Boot. Each BIOS could have a different name for this. These are the keywords to look for: UEFI, Secure Boot, Legacy Boot.
5. Toggle the Secure Boot setting to disabled and attempt to boot the machine.

In addition, you can try disabling BitLocker using the manage bde commands and see if that helps. Try booting the PC in WinRE mode and then refer the article

Disable-BitLocker



Kindly follow the steps to boot to WinRE mode.

1. Reboot the PC using Power button and once you see the manufacturer logo press the power button again.
2. Repeat step 1 at least 2-3 times until you see the System Recovery Options screen
3. On the System Recovery Options screen, select
   Troubleshoot> Advanced options > Command Prompt.

If the issue persists, I would suggest you to post your query on TechNet
