A realistic lifespan for common locks, plus the warning signs worth catching early.
A quality door lock lasts roughly seven to ten years on an exterior door, though heavy use, weather, and build quality move that number around. A back door used a few times a day outlives a front door used dozens of times, and a coastal-humidity environment wears hardware harder than a sheltered entry. When a lock starts acting up, it is usually telling you it is near the end.
The warning signs are worth knowing. A key that needs jiggling, a bolt that drags, a knob that turns loosely, or a deadbolt that no longer throws fully all point to wear. Caught early, many of these are a simple lock repair or an alignment fix rather than a full replacement.
If the lock is sound and you just want fresh keys, rekeying is the move. If it is worn or damaged, new lock installation is the better spend, and it is a chance to step up to a stronger deadbolt or a high-security lock. A smart lock through smart lock installation is another option at replacement time.

If you only take one thing from this, take this: handling a lock problem on purpose, before it becomes a crisis, is almost always cheaper and calmer than handling it in a panic at the worst possible moment. A little planning, a spare key, a rekey after a move, goes a long way.
