Hi josém78829581,

By locking PDF if you mean to secure PDF with password, please refer the steps provided in this help document: Securing PDFS with passwords, Adobe Acrobat

You will need Adobe Acrobat DC application to add security to the PDF.

Let us know if you are referring to something else or need any help.
