In plain words

Rekeying is really about knowing who can open your door. Over the life of a home, keys are lent to trades, handed to neighbours for the holidays, given to a cleaner or a dog walker, and copied at the hardware store. Nobody keeps a list. Rekeying draws a line: from today, the only working keys are the ones counted into your hand. Good practice afterwards is simple, and a locksmith will suggest it: know how many keys exist, know who holds each one, tag them with a colour or code rather than the address, and rekey again whenever a key leaves your control.

Sound familiar?

Your roommate moved out last weekend. Rent is settled, the room is empty, and the key is still on their ring. You trust them, but the lock on your front door should answer to the people who actually live here.

How the visit goes

How the visit goes

Double glass doors in metal frames with a horizontal push bar, beside a brick wall, with a parking lot and trees outside. — Chelsea Green
  1. 1

    Doors that belong to someone else

    A few openings around a home are not the occupant's to change, and sorting them out early avoids awkwardness later. In a condominium, the lobby, the garage, the locker room and the mailroom are the corporation's doors, and the suite door itself may need to remain on a system the building can access in an emergency. In a rental, the landlord has a say and must be given a key. A shared side entrance in a semi-detached or a duplex serves two households. The locksmith asks about each of these, confirms who needs to agree, and keeps them separate from the doors that are plainly yours.

  2. 2

    When a cylinder is swapped instead of repinned

    Sometimes the right move for a particular door is a new cylinder rather than new pins, and the locksmith says so before doing it. A cylinder with a keyway that cannot join the household key is replaced with one that can. A plug that has worn oval, springs that have collapsed, or a cylinder someone has already drilled is replaced because fresh pins would not fix its feel. In each case the replacement is pinned to the same new key as the rest of the house, so the swap is invisible in daily use. The old cylinder is handed to you or taken away as you prefer.

  3. 3

    For landlords: the tenant's copies and the paperwork

    After a rental unit is rekeyed, the incoming tenant receives their keys, the landlord keeps a copy as the tenancy rules expect, and the number issued is written on the move-in record so the count at move-out is easy to check. The former tenant's keys are retired. Where a building has several suites, the locksmith can keep each on its own key while the shared entry stays on a common one, and the note of which key belongs to which door becomes the start of a keying chart. That chart is what makes the next turnover a matter of one cylinder rather than a guessing game about who has what.

In the van

  • Graded bottom pin kit
  • Code cutter or key duplicator
  • Dry graphite or PTFE lubricant
  • Pinning tweezers and tray
  • Reset tool for user-rekeyable cylinders

What affects the quote

  1. 1

    Upgrades chosen during the visit

    Some people take the opportunity to replace a double-cylinder deadbolt with a thumb-turn model, add a reinforced strike or move to a heavier deadbolt. None of it is needed to rekey; each is a separate line.

  2. 2

    Several units in one building

    A landlord rekeying a duplex, a triplex or a small apartment building, with each suite on its own key and a common entry shared, has more cylinders and a keying chart to build, and the quote grows accordingly.

  3. 3

    Access to each door being rekeyed

    A rekeying visit goes smoothly when every door is reachable without delay: an empty unit, a cleared hallway, or someone available to let the locksmith into each room. Locked common areas, tenants who are out, or furniture blocking a cylinder all add time the locksmith accounts for on site.

Same fees day, night or weekend.

Lock Rekeying: questions

Advice · (226) 777-6122

Do the old keys really stop working?

Yes, at every cylinder that was rekeyed. Once the bottom pins are changed, a key cut to the old combination lifts them to the wrong heights and the plug will not turn. The locksmith proves this at each door by trying the old key after the new one, because any door missed from the list would still answer to the old key. That is also why the walk around the property at the start matters: every door meant to be included has to be on the list.

Can the garage side door, shed and gate be included?

Yes, and they usually should be, because a side door into the garage is the opening most often forgotten and left on an old key. Any pin-tumbler cylinder on the property can be pinned to the house key if its keyway allows: the man-door into the garage, a shed, a keyed gate latch, and many padlocks. A mailbox lock is usually a small cam lock that is replaced rather than repinned. Mention every opening when you book so the right blanks and cylinders are in the van.

Will my door hardware look any different afterwards?

No. The work happens inside the cylinder, so the bolt, handle, finish and strike plate stay exactly as they are, and nothing new is cut into the door. The only visible change is the key in your hand. If a cylinder does have to be replaced, because its keyway is incompatible with the others or it has worn out, the locksmith picks one in a matching finish so the door keeps a consistent look.

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.

Decades of seasons move a frame, and an older house often has a front door that locks easily in summer and fights in winter. Setting the strike with the seasons in mind, and choosing a lubricant that stays fluid in the cold, keeps it working year round.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (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.
