my notes are locked and i cant remember my code. can anyone help? this is incredibly important, whole my life is on my notes.

I'm sorry, but the bad news is that you cannot access the notes without remembering the password. As Apple points out in the support document linked above your name.......

Apple doesn't have access to locked notes and can’t help you access them if you forget your notes password.

More encouraging news is that you get unlimited tries at the password. Normally, Apple locks you out after 10 or so unsuccessful attempts.

The support document also points out that you can set up a new password for notes, but unfortunately that will not help you on the old notes with the old password.

Did the link at the top of the page help?
