Short answer: A quality deadbolt can turn smoothly for ten or fifteen years, or it can start grinding and sticking within two. The difference is rarely the brand you bought and almost always the handful of minutes of care nobody ever put into it. Here is what actually keeps a lock alive.

The single most common mistake we see is homeowners spraying an oil-based penetrant like WD-40 into a sticky lock. It frees things up for a week, then the oil attracts dust and grit and turns into a sticky paste that wears the pins faster than before. A pin-tumbler lock wants a dry lubricant: powdered graphite or a PTFE (Teflon-based) spray. Puff or spray a small amount into the keyway, insert and withdraw the key a dozen times to carry it through the mechanism, then wipe the blade clean so you are not tracking black graphite onto your hands and door. Do the latch and strike plate too, since a dragging latch bolt makes a lock feel far worse than it is. You rarely need much; a lock is a small machine, and a little goes a long way.
Most 'the lock is failing' calls are not the lock at all. Three culprits do the real damage. Grit and pocket lint ride in on your key and slowly abrade the pins. Moisture creeps into exterior cylinders and quietly corrodes the springs. And a door that has settled on its hinges throws the latch or deadbolt out of alignment, so every turn is forcing metal against metal. Before you condemn a lock, check whether the deadbolt slides freely when the door is open versus closed. If it moves cleanly open but binds when shut, the fix is the door or the strike plate, not a new lock, and tightening the top hinge screws or filing the strike opening solves it for free.
Tie lock care to something you already do seasonally, like changing smoke-detector batteries or resetting sprinkler timers, so it actually happens. Twice a year, walk every exterior door and gate: work the key and thumbturn to feel for stiffness, add dry lubricant to any cylinder that feels gritty, snug up loose handle and strike-plate screws with a screwdriver, and glance for rust or green corrosion around the keyway. Ten minutes across a whole house catches the small problems while they are still small. Locks almost never fail without warning; they get progressively harder to turn for months first. The homeowners who pay for a 2 a.m. lockout are usually the ones who felt the warning and ignored it.
