Lock Replacement & Upgrade
The brass handleset has gone blotchy and green where the winter salt reaches it, and the coating on the deadbolt is lifting in flakes. It still locks, but it looks tired beside the fresh paint on the door.

Sometimes the reason is simply that the hardware looks wrong or has weathered badly. Road salt, freeze-thaw and humid summers are hard on finishes, and a brass handleset can go blotchy while a lacquered knob peels. The locksmith helps you pick a finish that suits the exposure, whether matte black, satin nickel or a PVD brass that resists tarnish, and matches the deadbolt, handleset and interior levers so the entrance reads as one design. Function and grade are chosen alongside looks, so a door refreshed for appearance also comes out better protected.
How the visit goesThe house is fifteen years old and every exterior door still wears the light hardware the builder fitted: a short bolt, a thin strike held by two small screws, and a knob lock that never suited a street entrance.

How the visit goes

- 1
The rest of the openings
One failing lock is often the loudest of several, so the locksmith takes a short tour. The back door, the garage man-door, a basement walkout, a sliding patio door and a storm door all count, and so does the door from the garage into the house, which is often the lightest lock on the property. Each is noted for grade, condition and whether it has a deadbolt at all. You are not obliged to do them all at once; the value of the tour is a clear list ranked by what matters most, so the first replacement goes where it makes the largest difference.

Mounting the cylinder and the interior side
The exterior housing goes on with its tailpiece passing through the slot in the bolt, oriented as the maker specifies so the keyway sits upright. The interior thumb-turn or rose is offered up and the two long mounting screws are drawn down evenly by hand until firm, not crushed; zinc housings distort and threads strip under a drill, and an over-tight rose makes a lever heavy forever. On thick doors, extension kits bring screws and spindle to length. A knob or lever set adds the latch spindle and the spring cage, and the handle is checked to return crisply to level before the trim is snugged.

Simple habits that keep new hardware new
New locks ask very little. Once or twice a year, or at whatever interval the lock maker specifies, a puff of the lubricant that maker calls for in the keyway and a few turns of the key keep the pins moving freely, since the wrong product for that cylinder gathers grit instead of helping it. In winter, wipe salt spray off the exterior hardware when it appears, since salt is the finish's main enemy here. Each spring and fall, check that the hinge and strike screws are snug, because wood doors move with humidity and a dropped door makes a good lock feel worn. A key that starts to need coaxing is an early word from the cylinder.

What affects the quote
- 1
Keys cut
Each key is counted, and restricted keys cut against a card are a different item from standard blanks. Say how many people need one and the quote lists them.
- 2
Strike reinforcement and jamb repair
A reinforced strike with long screws is a modest addition; repairing a jamb split from a forced entry, or fitting a strike box into a frame that has never had one, adds labour and materials.
- 3
Restricted keyway system
Patented cylinders and controlled key blanks cost more than standard hardware and involve setting up your key records, which is quoted separately from an ordinary replacement.
Same fees day, night or weekend.
Lock Replacement & Upgrade: questions
My deadbolt only locks if I push the door. Will a new lock cure that?
The push is a sign the bolt and the strike pocket are out of line, which is a door and frame matter more than a lock fault. A new deadbolt is welcome if the old one is worn, but the visit also adjusts the strike, deepens the pocket or tightens hinges so the bolt throws freely with the door simply closed. Done together, the door locks with a fingertip and the new hardware works as designed.
I have just bought a house. What should I do about the locks?
Assume that copies of the old keys exist somewhere and act on the day you take possession. Walk every exterior door with the locksmith, keep hardware that is sound and have it rekeyed to a new key, replace hardware that is worn or too light, and add a deadbolt to any door that lacks one. Ask for everything to be keyed alike so you leave with one key and a known number of copies.
Can the same visit replace locks on more than one door, or does each door need its own appointment?
One visit usually covers every door on the job. The locksmith brings a range of cylinders and strikes, measures each door's backset and bore, and works through the list in order, front entrance first if a key change matters most there. Having a rough list ready, which doors, and whether they should end up on one key or several, lets the locksmith plan hardware before arriving rather than working it out door by door on site.

What the census means at the door
52%
Older homes. About 52% of homes in London were built in 1980 or earlier, according to the 2021 Census.
Layers of paint build up on older doors and frames, and a lock that seemed to fail is sometimes a latch glued shut by the last coat. Part of the visit in an older area is freeing hardware, cleaning the edges and checking the door swings true.
49%
A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).
In mixed neighbourhoods, a family may move from an apartment to a house or the other way around. A locksmith who knows both kinds of door can rekey the old place for the next occupant and set up the new one on the same visit.
