Lock Rekeying

Your basement tenant has given notice, and a new one arrives on the first. The lock on the separate entrance works perfectly well.

In plain words

One key for the whole house is a common request and usually achievable. Cylinders that share the same keyway, the shaped channel the key slides into, can all be pinned to the same new combination, so the front door, back door and garage entry answer to a single key. Where a door carries a lock from a different family with its own keyway, that cylinder is swapped for a matching one rather than repinned, and then it joins the group. The locksmith checks each lock face before the work begins so you know exactly which doors will share the key.

Sound familiar?

Every copy of your house key seems to work a little differently. One needs a jiggle, another sticks halfway, and the original wore down years ago. The lock itself is fine; the keys have drifted so far from each other that none fits cleanly.

How the visit goes

Lock Rekeying · London

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.
  1. 1

    Deciding the key groups

    Not every door in a home needs to answer to the same key, and the plan is written down before work starts. Most households want the exterior doors keyed alike so one key does everything. Some want exceptions: a basement suite on its own key, a home office or a storage room that visitors should not enter, a shed on a separate key that can be lent out without exposing the house. The locksmith sketches the groups with you, notes how many keys each group needs and who will hold them, and only then begins removing cylinders. Getting this straight first means no cylinder is pinned twice.

  2. 2

    Taking the cylinder out of the lock

    Each type of lock releases its cylinder in its own way, and the locksmith works door by door, finishing one before opening the next, so every entry stays lockable throughout. On a knob or lever set, the handle comes off after a retaining clip or set screw is released, and the cylinder slides out of the handle. On a deadbolt, the interior thumb-turn and housing are removed and the cylinder is withdrawn from the outside body. On an older mortise lock, a small set screw on the door edge is backed out and the cylinder unthreads from the case. Nothing is pried or forced; the door and trim stay untouched throughout.

  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.

What affects the quote

  1. 1

    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.

  2. 2

    No working key for a door

    When a cylinder must be shimmed, decoded or picked open before it can be repinned because no key exists for it, that extra step is included in the quote for that door.

  3. 3

    How many cylinders are included

    Each cylinder is removed, pinned and tested on its own, so a single deadbolt and a house with six exterior locks plus a shed and a gate are very different visits, and the quote follows the count.

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.

Period hardware on older homes deserves matching parts, not a mismatched modern set. A locksmith who works among such houses keeps finishes and styles that suit them, so a repaired or replaced lock still looks like it belongs to the door.

49%

A mix of homes. Single-detached houses make up about 49% of homes in London (2021 Census).

Mixed housing means a locksmith sees a bungalow in the morning and a condo tower in the afternoon. The stocked van has house-door deadbolts, suite-door cylinders and the finishes for each, so neither kind of customer waits for a second visit.
