Short answer: Most locks do not fail suddenly, they warn you for weeks first, then get ignored until they strand someone outside. A little routine care keeps your locks smooth, quiet, and reliable, and spares you an emergency call. Here is what actually helps and what quietly makes things worse.

Locks are precision mechanisms full of small pins and springs, and they need the right lubricant. Reach for a dry lubricant such as powdered graphite or a PTFE- or silicone-based lock lubricant, applied sparingly into the keyway, then work the key in and out a few times to distribute it. Avoid the common mistake of spraying general-purpose oil like WD-40 into a lock; oily products attract dust and grit, which over time forms a sticky paste that traps the pins and can make the problem worse than the squeak you started with. A light application once or twice a year, and after any lock feels dry or gritty, is plenty. Deadbolts, doorknob cylinders, and padlocks all benefit, and padlocks left outdoors especially appreciate a fresh treatment before winter.
When a key gets harder to turn, or a deadbolt only throws if you lift or pull the door, the lock is telling you something before it strands you. The usual culprits are a strike plate that no longer lines up with the bolt, a door that has shifted on worn or loose hinges, or a cylinder that is simply wearing out. A quick check: if the bolt slides freely when the door is open but binds when it is closed, the problem is alignment, not the lock itself, and often a strike plate adjustment or a hinge screw tightened down fixes it. Catching these early is the whole game, because the same worn cylinder or misaligned bolt that is merely annoying today is what fails at the worst possible moment. If a lock resists after cleaning and lubrication, have it looked at rather than forcing it, forcing is how keys snap off inside the mechanism.
Keys wear down with use, and a worn or bent key slowly chews at the pins every time you use it. Cut duplicates from a fresh original rather than copying a copy of a copy, since each generation loses a little accuracy, and retire any key that is visibly bent or has thinned teeth before it fails in the lock. For deadbolts, make sure the bolt extends fully into the frame, a bolt that only throws partway because of a tight strike is both a security weakness and extra strain on the mechanism. Tighten loose handle and strike-plate screws when you notice them, and give exterior hardware a wipe now and then so grit does not migrate into the keyway. None of this takes special tools, and it is the difference between a lock that lasts many years and one that quits early.
