The door key at the girlfriend’s house was not interested in entering the lock let alone turning. Went to Home Depot, picked up a small overpriced tube of graphite and lubed them up. Works like a brand new lock now.

      Yeah, basically just rub it on whatever metal surface needs lubricating. Use the side of the point like you’re shading a drawing to cover more surface area quicker. It worked well on sticky door latches, but I could see the key and lock mechanism being more trouble to lubricate this way.
