Short answer. Lock: one drop of Atkinson Oil Co. Door Lock & Hinge Oil into the keyway and the latch, then work the key and handle several times. Hinge: one drop at the top of the knuckle, swing the door, wipe off excess. If the lock maker says to use a dry lubricant in the keyway, follow the maker.
