Lock Replacement & Upgrade

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

After a break-in or an attempt, the door tells a story, and the new hardware should answer it. Splintered wood around the strike means the jamb gave before the lock did, so the repair pairs a heavier deadbolt with a reinforced strike and 75 millimetre screws that reach the framing behind the jamb. A bent bolt or cracked housing is replaced with a graded deadbolt whose bolt has a hardened core. A knob lock that was bumped or forced is swapped for a set with better pins. The aim is a whole opening that resists force, not merely a shinier lock.

Sound familiar?Milton

The call
The century home's original mortise lock takes a key the size of a spoon, sticks in humid weather and has worn its strike to a groove. You want a lock that works every day without giving up the old door.

How the visit goes

Illustrative locksmith scene
  1. Scene 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. Scene 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. Scene 3

    An opening that is stronger, not just newer

    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.

In the van

  • Chisels, mallet and hand screwdrivers
  • Cylinders, plug follower and pinning kit
  • Manufacturer-approved cylinder lubricant
  • Graded deadbolt
  • 75 millimetre strike and hinge screws

What shapes the quotePeru Lock Services

Special-order hardware
Most standard locks come from the van. A specific style, an unusual finish or a restricted system may need ordering, which affects scheduling and is noted in the quote rather than discovered on the day.
Older 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.
Type of lock
A knob set, a lever, a deadbolt, a full handleset with deadbolt above, a patio door lock and a keypad or smart deadbolt each carry a different hardware cost and take different time to fit.

Questions we hear most

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.

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.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 19 in 100 homes · newer homes
  • About 19% of homes in Milton were built in 1980 or earlier, according to the 2021 Census.Newer homes are built to standard bores and backsets, so nearly any modern deadbolt, lever set or smart lock fits straight on. The locksmith can offer a wide range of hardware knowing it will mount cleanly without new holes.
  • Single-detached houses make up about 57% of homes in Milton (2021 Census).Where housing types are mixed, the same lost-key call means different things. In a house, rekey every door on the property. In an apartment, rekey the suite door and check with management about the common entrance. The locksmith asks which it is first.
