Or skip the locks and fill the manholes with sand.  Then provide the service
folks those big suction trucks to remove the sand for servicing :)

It doesn't stop it, it just makes it slightly harder, and they'll go after
another point.


IMHO, I think manhole locks would only serve to HEIGHTEN the threat, not
minimize it.  Flag this under the whole "obscurity" category, but think
about this - if you're a vandal itching to do something stupid, and you see
a bunch of manhole covers and a couple of them have locks on them, which
ones are you going to target?  The ones with the locks, of course.  Why?
 Because by the very existence of the locks, it implies there's something of
considerable value beyond the lock.
