The correct way to change to sans serif font is to put
\renewcommand{\familydefault}{\sfdefault}
in the preamble.
If you want to use the helvetica font instead of the default Computer Modern
Sans Serif font, then use
\renewcommand{\sfdefault}{phv}
In lyx, you can do the latter by selecting helvetica as the font in the
document dialog.
