Sometimes when I depress the lock cylinder to open the rear hatch on my camper, the cylinder sticks in the depressed position.  It will pop back out when I close the hatch, usually.  Occasionally I have to bump the hatch adjacent to the lock.  Is this due to a need for lubrication, and if so, what lubricant do I use?  I have had locksmiths tell me not to lube a lock with anything, including graphite, claiming any lubricant would cause the lock to hold dirt.   On the other hand, I have used graphite to great advantage so far as I could tell.  Suggestions?  Thanks, David McNeely
