A Rekey on a Centurion Estate Home Is Rarely One Cylinder
On a Centurion estate home a rekey is rarely one cylinder. It is a front door, a scullery door, a door from the garage, a patio slider, a pedestrian gate and a driveway gate โ six locking points, and the money is not in the reconfiguring. It is in deciding, once, which of them should share a key. Our residential locksmith Centurion visits walk the perimeter as part of the job rather than charging to survey it.
Rekeying itself is straightforward: the cylinder already in your door is reconfigured so every previously issued key stops working. The hardware stays where it is, the appearance is unchanged, and you pay for labour rather than parts.
This page covers when that is the right answer and when it is not, the key structure decision that most households only get one cheap chance at, and what the visit involves on a property behind a boom.

Six Locking Points, One Decision
The question worth answering before a technician arrives is not how many keys you want. It is who needs to open what.
The default most households drift into is one key per door, accumulated over years as things were fitted and replaced by different people. Six keys on a ring is not security โ it is a set of doors that quietly stop being locked because the right key is never to hand, which our locksmith for car lockout technicians hear about constantly from people who keep the house keys in the car for exactly that reason.
The opposite default is one key for everything, which is convenient and occasionally wrong. If a domestic worker needs the gate and the scullery but not the study, or a cottage on the stand has its own tenant, keeping those separate is a deliberate choice rather than an oversight. Our locksmith for master key systems page explains how a small hierarchy is planned so one person holds only what they need.
Whichever you choose, deciding it during a rekey costs a fraction of arranging it afterwards, because the labour is already being paid for. It is the single cheapest moment a household gets, and most people spend it without noticing โ which is why our locksmith for lock change visits raise it before any work starts.
Rekey, or Replace?
Both reach the same security outcome by different routes. Both get quoted so you choose rather than being steered towards the more expensive one.
| ย | Rekey the existing cylinder | Replace the hardware |
|---|---|---|
| What happens | The cylinder is reconfigured so previously issued keys no longer operate it. It stays in the door and nothing looks different. | The cylinder comes out and a new one goes in, measured to the door and tested before the visit ends. |
| Right when | The hardware is sound and the concern is who holds a key โ a transfer, a departed tenant, a lost set, a contractor. | The mechanism is worn past reliability, wrong for its exposure, or has been forced at some point. |
| On gates specifically | Works where the mechanism is healthy, but does nothing about a cylinder that was never rated for outdoors in the first place. | The right answer where an interior-grade cylinder has been sitting outside doing several hundred cycles a week. |
| Cost | The lower figure, because you are paying for labour rather than parts. | Higher, and worth it in the cases above rather than as a default choice. |
Where the fault is neither โ a lock that is simply dry, or a door that has dropped โ a repair or an adjustment is cheaper than both, and our locksmith for lock repair page sets out the test that tells you which of the three you have.
When Centurion Households Rekey
Six situations covering most of this work, and why reconfiguring rather than replacing is usually right in each.
Transfer on an estate home
The working key count is genuinely unknown and the hardware is usually fine. The textbook case for a rekey rather than new cylinders.
A set of keys has been lost
Somewhere out there is a working key to the property. If anything on the ring identified the address, that matters considerably more.
Domestic staff have changed
Ordinary housekeeping rather than an accusation. Rekeying at a change of staff costs less than replacement and settles the question.
A contractor never returned a key
Extremely common after building work. Nobody counted how many were issued, including the contractor who issued them.
Too many separate keys
Six keys for one property is a keyring nobody wants to carry. Bringing them onto one during a rekey costs a fraction of doing it later.
Cottage or flatlet on the stand
Where a tenant needs their own access without the main house, keeping the keying separate is deliberate rather than accidental.
Why the Key Count Is Always Higher Than People Think
This is the honest reason rekeying exists, and it has nothing to do with anybody behaving badly.
Keys go to a domestic worker, a gardener, a family member, a neighbour who fed the dogs over a holiday, a contractor who was on the property for three weeks. On a transfer, add the previous owner's circle and an agent who held a set during the sale.
None of that is recorded anywhere and none of it can be reconstructed. Asking for keys back produces some of them and no certainty at all, because a returned key may have been copied at any point in the eighteen months somebody held it. It is the same problem our commercial locksmith Centurion team solves for premises with a restricted profile and a register.
Rekeying ends the question rather than narrowing it. Every key issued before today stops working, whoever holds it and whatever they did with it. On an estate there is a second half to the same job, though โ remotes, boom tags and fobs are the estate's credentials and no locksmith affects them, which is a call to the managing agent. Our locksmith for home lockout page covers the same estate-access reality from the urgent side.
What the Visit Involves
Five steps, and the first is yours. On a Centurion property it saves more time than anything a technician does on the road.
- Step 1
You clear the gate
Estate name and a call to the guardhouse. An unannounced van full of tools does not come through a boom, and that delay is longer than the drive.
- Step 2
Every locking point counted
Front, scullery, the door from the garage, any slider, the pedestrian gate and the driveway gate. Finding them now keeps the quote accurate.
- Step 3
Each cylinder checked first
Rekeying a mechanism that is already failing is money wasted. Where a cylinder is worn past reliability that gets said before the work rather than after.
- Step 4
The key structure decided
Which doors share a key and which are held separately, settled in one conversation rather than accumulated over years of separate jobs.
- Step 5
Reconfigured, tested and handed over
The hardware stays in the doors, nothing leaves the property, and every new key is handed to you with no record of it kept.
Doing the whole property at once?
It costs a fraction of doing it one door at a time over several months. Call with a rough count for a single figure covering the lot.
How the Visit Works
Operating commitments rather than claims, each visible during the job itself.
Every key produced during the visit is handed to whoever authorised the work. Nothing is retained and no record of the key is kept โ which on a rekey is the entire point of the exercise.

The two are frequently presented as alternatives at similar prices, and they are not. Knowing which one your situation calls for is worth more than any discussion of hardware.
Rekey when the hardware is sound and the problem is who holds a key. The cylinder already in the door is reconfigured so everything previously issued stops working, the door is untouched, the appearance is unchanged, and you pay for labour rather than parts. That covers a staff change, a tenant leaving, a lost bunch, a new purchase and the end of a renovation โ which is most of the reasons anybody calls.
Replace when the hardware itself has reached the end, when it is the wrong specification for its position, or when the security level genuinely needs to go up. A worn cylinder that only accepts one particular key held a certain way is a replacement. An indoor-grade cylinder on an outdoor gate is a replacement. A door that has been forced is a replacement.
The test that separates them is simple: is anything wrong with the lock, or is something wrong with the list of people who can open it? If it is the second, replacing hardware is buying parts to solve an administrative problem.
A technician who reaches for replacement without asking that question is selling parts, and it is a reasonable thing to ask directly on the phone. Where replacement genuinely is the answer, it is quoted per opening โ see locksmith for lock change in Centurion.
When a Rekey Is Not Enough
There are situations where reconfiguring the existing cylinders is the wrong answer, and it is worth being straightforward about them rather than selling the cheaper job in every case.
The first is where a key has been lost along with information identifying the property โ an address on a tag, an estate name, a remote for the gate on the same ring. In that case the exposure is not theoretical and the response should be prompt and complete rather than partial.
The second is where the hardware is at the end of its life anyway. Rekeying a cylinder that is already worn produces a lock that fails on its own schedule shortly afterwards, and you will have paid twice for the same problem.
The third is where the structure cannot be built out of what is there. A property with six openings on six unrelated cylinders from four different eras cannot be brought onto a sensible key hierarchy without some of those cylinders being changed โ not because they are faulty, but because they are incompatible with each other.
And the fourth is after a forced entry, where the mechanism, the strike and frequently the frame have all taken load. Nothing about reconfiguring a lock addresses a component that has been distorted.
In each of those the honest answer costs more, and being told plainly which one applies is the difference between a job that holds and one that gets revisited.
