removing read only option from word 2010

[curioustechy]

I've created a document using office 2003 & set a password to open it as well as another password for allowing editing. Now I'm using office 2010. I wanted to remove both the passwords. But could only remove the first one. How to remove the password for editing

Just go to file and select Save As..
That means save it as a new document. I don't think there is an option to remove password from a document.
