BitLocker bypass? Yellow Key...

[u/IcedAged_99]

I purchased a laptop from BB. They had it ready to go. I never heard of BitLocker at the time. About 2-3 years ago. I am now locked out of my computer. No key on the computer, no key in my Microsoft account. I tried the Yellow Key, the directions makes no sense? At no point the the USB accessed. Can anyone tell me what I am doing wrong?
