- The call
- The 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.
Three teenagers, a dog walker, a cleaner and one house key that keeps going missing. You are tired of cutting copies and would rather give each person a code you can switch off, with a proper deadbolt behind it.
In plain words
A keypad or smart lock is a lock replacement with a few extra steps, and it suits households where keys circulate widely. The locksmith fits the new deadbolt to the existing bore, checks that the bolt throws freely so the motor is never straining against a misaligned strike, sets up user codes and any phone pairing, and shows you the mechanical override and the battery warning. Because these locks still rely on a bolt and a strike, the same attention goes into the frame as for any deadbolt. You gain convenience without giving up the mechanical basics that make a door hard to force.

How the visit goes
Scene 1
Measuring the existing preparation
Before any product is chosen the door is measured. Backset first, the distance from the door edge to the centre of the bore, which on most doors here is 60 or 70 millimetres. Then the cross-bore diameter, the edge-bore size, the shape of the latch faceplate, the door thickness and the handing. The strike cut-out and any glass, trim or storm door that limits where hardware can sit are noted too. These few numbers decide which locks will drop straight into the door and which would need a filler plate, an extension kit or fresh drilling, so they are written down before the catalogue is opened.
Scene 2
Installing a keypad or smart deadbolt
A smart lock is fitted like any deadbolt, then brought to life. The bolt and exterior keypad go on first, the interior module with its battery pack after, and the door is closed so the lock can learn where the bolt sits; a bolt that meets resistance in the strike is corrected before pairing, because a straining motor drains batteries and fails early. Codes are programmed for each person, auto-lock and sound settings are set to your liking, any phone or hub pairing is completed, and the mechanical override cylinder is tested with its key. Fresh batteries go in last.
Scene 3
A record of what went on the door
You are told plainly what was fitted: the maker and model, the grade, the function and finish of each lock, whether the strike was reinforced, and how the doors are keyed. The instruction sheets and packaging stay with you, since they carry the model numbers needed for a matching lever or a spare cylinder later. The old hardware is handed over or taken away as you prefer; a sound old cylinder can be worth keeping as a spare. For a rental, this account doubles as the note a landlord or property manager will want about the new keys.

What shapes the quotePreston Locksmith Co.
- Condition of the old hardware
- Hardware that comes off cleanly is one thing; painted-over trim, seized or stripped screws and a cylinder that has to be drilled out add time before the new lock can go on.
- Smart lock setup
- Fitting a keypad or smart deadbolt includes programming codes, pairing to a phone or hub and calibrating the bolt, which is time on top of the mechanical installation and is named in the quote.
- 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.

Good questions about locks
What information helps before the visit?
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.
Can a lever replace a knob on the same door?
Yes, and it is a common change for anyone who finds a knob hard to grip. Levers use the same bore and backset as knobs, so the swap is usually a direct fit. Levers are handed, so the locksmith checks which way the door swings and chooses or adjusts the lever accordingly. A keyed entry lever pairs well with a deadbolt above it, and interior passage and privacy levers complete the set.
What does a higher grade of lock actually give me?
Grades follow ANSI/BHMA standards, with Grade 1 the highest and Grade 3 the lightest, and residential hardware carries a separate label that scores security, durability and finish. The grade reports how the lock performed on the standard's own operational, strength and security tests; a higher grade often comes with a longer bolt, a sturdier housing, pins that resist picking and a strike built to anchor into the framing, but those features are worth confirming on the specific model rather than assumed from the grade alone.

2021 census: what it means at the door
Every square is one home in a hundred.
- 48 in 100 homes · mixed ages
- 57 in 100 homes · mixed housing
- About 48% of homes in Cambridge were built in 1980 or earlier, according to the 2021 Census.In areas with homes from many decades, a locksmith gets to match the solution to the house rather than apply one answer everywhere. Period hardware stays on the houses that suit it; modern security goes where the door and the household want it.
- Single-detached houses make up about 57% of homes in Cambridge (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.
