While uploading any document on FLEX is easy sometimes a locked document will require an extra step before it can be loaded to FLEX.
For any locked PDF, you can unlock the document by saving the document in .pdf format again, you can achieve this by using any programs that help you to convert files or retains the original format. Once you have the new file labelled as 'my file (1).pdf', you can now upload this file to FLEX.
