Lock Replacement & Upgrade

Every morning the front door key needs the same little dance: push in, lift, wiggle, turn. It has been getting worse for a year, and this week it took three tries in the cold before the deadbolt finally gave.

Lock Replacement & Upgrade

In plain words

Not every complaint about a lock ends in a new lock, and a good visit says so. A cylinder that turns stiffly may only need cleaning and fresh pins; a lost key calls for rekeying, which keeps the hardware and changes the key; a loose lever often wants a tightened spindle. Replacement earns its place when the mechanism is worn through, the housing is damaged, the grade was never adequate for the entrance, or you want a different function, finish or a keypad. The locksmith lays the three routes side by side so the choice rests on what the door needs rather than on what is in the van.

How the visit goes

How the visit goes

  1. The key plan for the whole house

    A lock is only half of a system; the other half is who holds which key. The locksmith asks how many exterior doors there are, which ones should open with the same key, whether a garage man-door or a shed should join them, and who in the household needs a key of their own. If keys have been lent out over the years, the plan can retire all of them at once. Where copying keys without permission is a worry, a restricted keyway can be offered. Settling this before the hardware is chosen means the new locks arrive ready to be pinned alike rather than fixed up afterwards.

  2. Stepping up the grade of a deadbolt

    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.

  3. Keys counted, named and planned

    You receive the agreed number of keys, cut from the new pinning and tried in every door they should open, plus any code cards for a restricted system, which are what future copies are cut from. It is worth deciding on the spot who gets one and where the spare lives, ideally with a trusted neighbour or in a lockbox rather than in a drawer inside. If the house is now on a single key, retire every old key so none can be confused with the new one. A written list of which key does what goes in the home file.

What affects the quote

Same fees day, night or weekend

  1. 1Keys 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. 2Older and mortise hardware

    Servicing an original mortise case, sourcing a compatible cylinder or fitting a conversion plate on a century door involves more assessment and fitting time than a standard cylindrical replacement.

  3. 3Changes to the door preparation

    Adjusting a strike mortise is minor; boring a new hole for a deadbolt, fitting a filler plate over an old mortise pocket or adapting a thick door with extension kits is quoted as its own item.

Lock Replacement & Upgrade: questions

How long does a lock replacement take?

A straightforward like-for-like deadbolt or knob set on a standard door is often a matter of an hour or less including testing. Add time for a reinforced strike, for keying several locks alike and cutting keys, for a smart lock's setup and pairing, and for repairing a split jamb or adapting an older door. When several entrances are done together, the locksmith gives a realistic window before starting so you can plan the day.

Which finishes stand up to salt and winter?

Finish is one of the three categories on the residential hardware label, and it covers exposure to sun, humidity, salt and skin oils. In practice, PVD brass, satin nickel and stainless finishes tolerate a salted driveway well, powder-coated black holds up when it is not chipped, and traditional lacquered brass tends to bloom green where salt reaches it. A storm door or a small overhang helps any finish, and wiping salt off in a thaw helps more.

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.
