Rekeying locks in Fourways
Rekeying changes what is inside your lock so that a new key works and every old key stops. The hardware stays where it is, which is what separates it from a lock change in Fourways, where you are buying the cylinder as well as the labour. For anyone who has just moved into an estate home or a complex unit, it answers the question that actually matters: how many keys to this door exist, and who has them?
The process, briefly
A standard cylinder holds a stack of small pins at varying heights. The right key raises every pin to exactly the right level and the plug turns. Rekeying swaps those pins for a different arrangement — new key works, old keys no longer line up.
The lock comes off, is re-pinned and goes straight back on. No new fixings, no marks, no repainting, and nothing about the outside of your door changes.
Why it matters more in a complex
A freestanding house that has changed hands twice has an unknown number of keys in circulation. A unit in a complex that has changed hands six times over twenty years, with contractors, agents and managing agents in between, has considerably more.
None of that is anyone's fault — it is simply what happens over time. Rekeying draws a line under it in a single visit, without you having to reconstruct a history nobody recorded. Everything on the domestic side is covered under residential locksmith services.
One key for the whole property
Where cylinders are compatible, several doors can be re-pinned to a single key: front door, back door, security gate, garage side door. For most households that is a genuine daily improvement.
It is worth deciding deliberately rather than drifting into it. One key is more convenient and correspondingly more significant to lose. If your unit also sits behind a complex system, ask the managing agent how your door is expected to fit into it before committing.

When we would tell you not to bother
If the lock is worn, has been forced, or is simply poor hardware, re-pinning puts fresh pins into a mechanism already on its way out. That is paying twice.
It is also the wrong spend if you were planning a security upgrade anyway. Doing both at one visit is cheaper than doing them separately, and that conversation belongs with a lock replacement rather than a rekey.
Why this is the first job after a move in Fourways
Almost everybody who buys or rents in this part of Johannesburg inherits a key problem they cannot see. The property has been through owners, tenants, agents, gardeners, painters, a pool service and at least one neighbour who kept a set for a holiday, and nobody has ever counted.
Being handed three sets on handover day tells you nothing at all about how many exist. The question is not whether anyone involved was untrustworthy — it is that nobody, including them, could give you a number if you asked.
That makes it a first-week job rather than a first-year one. A handover follows an open house, a run of viewings and a period when keys were circulating more freely than at any other point in the property's life, which is exactly the moment to draw a line under it. There is more in moving into a complex.
What a counted set actually means
The part of this job that matters most sounds like paperwork, and it is the same discipline behind any master key system. When the pins are changed, somebody should write down how many keys were produced and who received each one, and hand that note over with the keys.
It sounds excessive for a house and it is the entire point of the exercise. A rekey followed by an uncounted handful of keys walking out of the door has simply restarted the problem you paid to solve, and in two years you are back to not being able to answer the question.
For a landlord or a managing agent running several units in Gauteng it is not optional at all. The record is what makes a handover checkable, and across a few tenancies it is worth considerably more than the hardware itself.
Why estates prefer it to a hardware change
A great many properties across Fourways, Dainfern, Steyn City and the surrounding complexes sit inside developments that regulate what may be fitted to any door visible from common property. Finish, style and sometimes brand are specified, and fitting something else can mean removing it again at your own cost.
Re-pinning sidesteps that completely, which is why it is approved without discussion where a hardware change needs a conversation. Nothing visible changes at all — the same lock stays on the same door with the same finish — while every key ever cut for it stops working.
It also applies to developments running their own restricted key systems that each unit is expected to join. Where that is the case, say so when you book, because it changes which cylinders can go in. Anything involving communal doors is commercial locksmith work rather than a domestic visit.
What it does not solve
Rekeying answers one question extremely well and it is honest to be clear about what it leaves untouched. It changes who can open a lock. It does nothing whatever about how good that lock is.
If the cylinder is a builder-grade item that would not resist a determined attempt, re-pinning it produces a builder-grade cylinder that your predecessors' keys no longer fit. That is a real improvement and it is not the same as an upgrade. Where the hardware itself is the weak point, the conversation is about high security locks instead.
Nor does it help with a door that has moved, a strike plate held by short screws, or a gate that has seized. Those are separate jobs, and the sensible approach is to have somebody look at the whole property once rather than solving one thing at a time across three visits.
Keying several doors alike, and when not to
Most households in northern Johannesburg carry more keys than they need. A front door key, a back door key, a security gate key, a garage key and something for the estate gate — all different, all on one ring, none labelled.
Keying alike solves that during a rekey at very little extra cost, because the cylinders are open anyway. One key opens every external door, the ring gets smaller, and nobody stands in the rain trying four keys in the dark.
There is a trade-off worth stating. One key for everything means one lost key affects everything, and anybody you hand a key to for one purpose can open all of it. Where somebody needs partial access — a gardener who should reach the store and not the house — the answer is master key systems rather than keying everything alike.
What happens on the day
Nothing about a rekey is dramatic, which is worth saying because people expect more disruption than there is. The cylinders come out of the doors, the pins inside are changed to match a new key, and they go back into the same doors with the same screws and the same finish.
Nothing is drilled, nothing is left open, and at no point is the property standing unsecured. If a door has to be worked on for twenty minutes, that door is closed and the rest of the house is as it was.
At the end you get the new keys and a count of them. Anything found along the way that should not be re-pinned — a seized gate lock, a cylinder worn enough to be on borrowed time — is pointed out and priced separately rather than quietly included, which is the same principle behind every emergency locksmith callout we run.
Doing it across a property in one visit
On a typical property in the Fourways ring there are more cylinders than people count. A front door, a back or scullery door, a security gate over the entrance, a pedestrian gate, a garage side door, sometimes a store or a cottage. Doing them piecemeal over three visits costs considerably more than all at once.
It is worth walking the property with the technician at the start rather than pointing at the front door and leaving them to it. Half the value of the visit is finding the two cylinders you had forgotten about, which are reliably the ones nobody has turned since last winter.
That walk also produces the honest list of what should not be re-pinned at all because it needs replacing. Somebody who tells you a seized gate lock is beyond re-pinning is doing you a favour, and it is the same conversation as any lock repair visit.

Rekeying — common questions
How is rekeying different from changing the lock?
The lock stays exactly where it is. Only the pins inside the cylinder change, so every key cut before that moment stops working while nothing about the door alters visibly. A lock change replaces the hardware itself, which costs more and is only worth doing if the hardware is the problem.
We have just moved in. Should we rekey or replace?
Rekey, unless the hardware is tired anyway or you want to raise the grade at the same time. It addresses the real risk — an unknown number of keys in unknown hands — for less money than a lock change in Johannesburg and without changing anything visible.
Will our estate or body corporate allow it?
Almost always, and that is one of the main reasons to prefer it. Nothing visible changes, so rules about finish and style on doors facing common property simply do not come into it. If your development runs its own restricted key system, mention that when you book because it changes which cylinders can be used.
How long does it take?
For a typical house in Fourways with four or five external cylinders, under two hours including the walk-round, which is quicker than any lock change in Gauteng across the same doors. That covers the walk-round and the count at the end. Nothing needs ordering in advance and nothing is taken away, so it is a single visit rather than a return trip.
Can you make all our doors take the same key?
Usually, where the cylinders are compatible, and where they are not those can be swapped during a lock change for ones that are. It is worth deciding deliberately rather than by default: one key is convenient, and it also means anybody you hand a key to can open everything.
Does rekeying make my locks more secure?
It changes who can open them, which is usually the actual problem. It does not change how good the lock is. If the cylinder itself is the weak point that is a different conversation, and you should be told which of the two you have before anything starts.
We have just bought in an estate. Rekey or replace?
If the locks are sound and reasonably modern, rekeying deals with the real risk — unknown keys — for less money and without touching the appearance of the door, which matters where hardware is regulated. Replace only if the existing lock is weak or worn.
Does rekeying leave the lock as secure as before?
Yes, assuming the lock was in good order to begin with. The mechanism is unchanged in strength; only the pin combination differs. If the lock was already poor, rekeying does not improve that and we will say so.
Can all my doors be put on one key?
Usually, provided the cylinders are of compatible types — and where they are not, those can be swapped for ones that are. Worth thinking about deliberately, since a single key is both more convenient and more consequential to lose.
Can any lock be rekeyed?
Most standard pin cylinders can. Some older or unusual locks cannot be re-pinned economically, and restricted systems have to go back through the authorised channel. We check on site before quoting.
