I have a four lever Chubb lock which sometimes sticks when it is turned
towards the LOCK position. I looked at the mechanism and it appears that
it is either the lever(s) not moving properly, or the adjacent locking bar
that fits in the levers. I would like to clean the area (I suspect there#s
some dirt there) and re lubricate it, but I'm not sure what lubrication to
use. It looks as if there's some light grease that has been used, rather
than oil (I may be wrong).
The key or mechanism isn't well worn is it? or the keys poor copies ?
They assemble them with normal grease. However, if poss try to avoid the
places where the key will touch or users may object.
I normally just spray wd40 in situ though :-)

Lever locks (lever padlocks too) can use almost anything as a
lubricant, so long as it doesn't go soapy or waxy with age. Yery
little, of a very light grease is OK, or even vaseline. I use a
PTFE-loaded white grease, sold for bicycle wheels, because it has good
rain resistance. Powdered graphite is OK too, but you'll probably
need to clean old grease from out of the case first - it's not a good
Cylinder locks should only be lubricated with powdered graphite.
WD40 is a bad idea on either.
