Someone tried the back door while you were away. The jamb is splintered around the strike, the bolt is bent, and the knob turns with a grinding feel.
Lock replacement and upgrade is the service that takes tired or under-built door hardware off and puts hardware suited to the door in its place. It ranges from a like-for-like deadbolt on a back door to a complete refit of every entrance with heavier-grade locks, reinforced strikes and one key for the house. The locksmith first confirms that the person ordering the work has the right to change the lock, then examines the door, measures the existing preparation and recommends hardware that fits it cleanly. The visit ends with each lock tested from both sides, keys in your hand and the packaging and instructions left with you.

Scene 1
The locksmith works the existing hardware the way you do every day and watches for the tell-tale signs. A key that must be lifted or wiggled points to worn pins or a worn key. A knob that turns too far, or a lever that droops, suggests a tired spindle or spring. A latch that stays retracted, or a bolt that stops short, can be internal wear or something outside the lock altogether. Doing this with the door open first, then closed, separates faults inside the mechanism from faults in the fit of the door, and that distinction decides whether new hardware is the answer or part of the answer.
Scene 2
When the brief is a stronger door, the new deadbolt is chosen for what is inside it: a bolt with a full 25 millimetre throw and a hardened steel insert that spins against a saw, a housing that stands low so a wrench has nothing to grip, and a cylinder with pins that resist picking and bumping. Fitting follows the normal steps, but the locksmith confirms the bolt reaches full extension with the door closed, because a high-grade bolt seated halfway into a shallow pocket behaves like a low-grade one. The strike is upgraded alongside it so both halves of the lock share the same standard.
Scene 3
Where the strike was reinforced, the improvement is mostly invisible and worth understanding. Long screws now tie the strike through the jamb into the framing, the pocket has been cut to take the whole bolt, and any split wood has been repaired. Together these make the frame the equal of the deadbolt, which is the part most break-ins defeat. The locksmith points out what changed so you can check it yourself: a bolt that seats fully with the door closed and a strike that stays put under a firm push. A twice-yearly look at those screws keeps it that way.

The lock hardware is the same; the door construction changes the method. Steel and fibreglass doors have a wooden or composite block inside the lock stile, and existing bores are used wherever possible. Where a new deadbolt must be added, the locksmith drills with a jig and bits suited to the skin so the hole is clean and square, and fits an edge plate designed for that door. Insulated doors also move less with humidity, so alignment tends to hold well.
Photographs of each lock from outside and inside, plus one of the door edge showing the latch plate and one of the strike on the frame, tell the locksmith most of what they need. Add the door thickness if you can measure it, whether the door is wood, steel or fibreglass, the finish you want to match, how many doors are involved and whether you want them all on one key.
Usually, yes. Most residential doors are prepared to standard sizes, a 54 millimetre cross bore and a backset of 60 or 70 millimetres, and most modern hardware adjusts between those backsets. The locksmith measures before choosing, so the new lock is matched to the door rather than the other way around. Where an older mortise lock or an unusual bore is found, filler plates, extension kits or a carefully jigged new bore bring the door to standard.
