I have the correct recuperation key for Bitlocker but can't access the OS/Drive

Question

I had one Windows on one hard drive and then installed a second windows on another drive. So I had two Windows two boot on one or another (both Windows 11) Then I Bitlocker the second drive directly from its Windows but when it did the first retart to verify the keys, the blue screen demands me the bitlocker key but the key didnt work. I know the key is correct because de key ID is correct.

I tried going throughthe advance recovery option and manage-bde etc. but it prompts that the key couldn't unlock the volume (also from the other Windows 11 through the terminal), I tried the key directly through the blue screen, and through the first drive Windows, and unpluging the ssd from the computer and pluging it again with and usb adaptor, I tried also in another computer. When I tried through another Windows it prompts "key doesnt match with this unit". I tried writing it with the keyboard and through copy-pasting the code.

Hello Sutil X,

here are some steps you can try:

1. Make sure you're using the correct BitLocker recovery key.
2. Make sure that the time and date in your computer's BIOS are set correctly. If the time and date are incorrect, it may cause BitLocker-encrypted drives to fail to unlock.
3. Try to boot your computer using Windows installation media and use the "Repair Computer" option to fix the boot issue. During the repair process, you can try to unlock the drive using the BitLocker recovery key.
4. If your computer boots with UEFI, you can try disabling the "Safe Boot" option and then restart your computer and try to unlock the drive.

Best regards,

Lei
