Short answer: Locks are mechanical, and like anything mechanical they wear, gum up, and drift out of alignment over time. A little regular upkeep keeps them turning smoothly and spares you the cost and stress of an emergency call.

When a key starts to feel gritty or the cylinder turns hard, the instinct is to reach for a spray oil. The trouble is that heavy petroleum lubricants attract dust and grit, which eventually cakes the pins and makes the problem worse. For pin-tumbler locks, a dry lubricant such as powdered graphite or a PTFE (Teflon) based spray is the safer choice, because it lets the internals move without leaving a sticky film behind. Apply a small amount, work the key in and out a few times to distribute it, and wipe away the excess. Doing this once or twice a year keeps most cylinders smooth for a long time.
A key that sticks or a bolt that drags is your lock warning you, and forcing it is exactly how keys snap off inside cylinders. Start simple: try a spare key in case your everyday key is worn, clear any debris from the keyway, and add a touch of dry lubricant. If a deadbolt only throws when you lift or lean on the door, the real issue is usually alignment, meaning the door has sagged or the strike plate has shifted, not the lock itself. Catching this early keeps it a five-minute adjustment instead of a broken bolt at the worst possible moment.
A lock is only as reliable as the door around it. Over the years, hinge screws loosen and doors settle, so the bolt stops lining up cleanly with the strike plate, and you feel that as a lock you have to wrestle. Tightening the hinge screws, swapping in a longer screw that bites into the framing behind the jamb, and adjusting the strike so the bolt slides home freely all extend the life of the lock and make the door seat more securely. When the misalignment is severe or the frame itself is damaged, that is the moment to bring in a locksmith rather than keep muscling the door shut.
