With the cheap locks I've seen, that should be enough. But even if not, the
lock body will just be soft "pot metal", so it's easy to drill once the
(relatively) hard skin of the knob is out of the way.
Of course, it depends somewhat on what your time is worth to you. But even
a medium-grade lock is only $30 or so, while a locksmith on a Saturday is
bound to be several times that much.
