When changing the locks is the right call
There are four moments when we would change locks without hesitating. The first is taking transfer of a property — you have no idea how many keys exist or who still has one. The second is losing a key that was on a ring with anything identifying your address. The third is the end of a tenancy or a shared living arrangement, where the key was legitimately issued and simply should not open the door any more. The fourth is after an attempted break-in, where the cylinder may look intact but has been stressed and will fail without warning.
Everything else is a judgement call and we will make it with you honestly. A sticky lock is often a wear or alignment issue, not a security one, and that conversation belongs under general residential locksmith work rather than an unnecessary replacement.
Replace the cylinder or re-key the lock?
These are two different jobs with the same outcome for you: the old keys stop working. Re-keying re-pins the existing lock to a new key and suits good-quality hardware in sound condition — it is faster and it costs less. Replacing the cylinder makes sense when the lock is worn, when the grade is too low for the door it sits on, or when you want anti-snap and anti-bump protection you never had. A technician can tell which applies within a minute of looking at the door, and you will hear the price for both options before anything is fitted.
While we are there, it is worth asking about keying doors alike. Running the front door, back door, security gate and garage side entrance on one key costs very little extra at the point of replacement and saves years of fumbling in the dark. That approach scales up neatly into the hierarchies we build for businesses under our commercial key control service.
Landlords, agents and handover days
Rental changeovers around Bryanston run to a tight schedule, and lock changes are usually the last thing anyone remembers. Book the slot for handover day and we work to it: cylinders swapped, a stated number of keys handed to the incoming tenant, and written confirmation of exactly how many were issued. That last detail matters more than it sounds — it is the document that settles the argument at the end of the lease about how many keys should come back.
For furnished and short-let properties, restricted key profiles are worth the extra spend. A guest cannot walk to a kiosk and cut a copy, because the blank is controlled. It is the same principle we apply to office buildings, scaled to a single unit.
Urgent lock changes and after-hours work
Some lock changes cannot wait until morning. If keys have been stolen along with a handbag, or a door has been forced and no longer secures, phone immediately — that is handled as an emergency locksmith callout in Bryanston and a technician is dispatched at once. We secure the property first and complete the permanent replacement either on the spot or as soon as the right part is in hand.
For everything non-urgent, book a daytime slot when you book a locksmith in Bryanston and we will hold the time.
If you are not yet sure whether this is the job you need, it is worth comparing it against everything else on the Bryanston locksmith services, because the difference between changing a lock and changing what it answers to is the difference between two quite separate bills.
Doing several doors at once, and why it costs less
The commonest way this job ends up costing more than it should is doing the front door now and the rest eventually. Every separate visit carries its own callout, and on a property with five external cylinders that is four callouts nobody needed to pay for.
It is worth walking the property with the technician at the start rather than pointing at one door and leaving them to it. Half the value of the visit is finding the two cylinders you had forgotten about — the store, the gate onto the servitude, the door between the garage and the house — which are reliably the ones nobody has turned since last winter.
That walk also produces the honest list of what should not be replaced at all. A cylinder that is simply dirty rather than worn wants cleaning, not buying, and saying so is part of the job. Most of what turns up that way is lock repair at a fraction of the cost.
The question to settle before anything is ordered
There are two quite different jobs that both get described as changing the locks, and they cost very different amounts. Getting the right one is worth more than shopping around on price.
If the problem is that keys exist which you cannot account for — after a move, after a tenant, after a set went missing — then the hardware is not at fault and does not need replacing. Rekeying changes the pins inside the cylinders already on the doors, so every previously cut key stops working while the locks, the finish and the handles stay exactly as they are.
Replacement earns its cost in three situations: the hardware is genuinely tired, you want to raise the grade at the same time, or a cylinder was never suitable for the door it is on. If none of those applies, re-pinning does the same job for less, and a locksmith who does not raise it is not giving you the full picture.
What gets carried, and what has to be ordered
Common cylinder types travel on the vehicle, which is why a straightforward change across a Bryanston house is normally finished on the first visit with keys handed over on site rather than posted or collected later.
What needs ordering is unusual hardware, older patterns where a modern equivalent has to be matched, and anything that has to satisfy a complex or estate specification. Describing the door on the phone — the shape of the lock, whether the key has a single row of cuts or a track down its face, what the handle does — usually settles which situation you are in before anybody leaves.
Where a part has to come, the door is left secure and working rather than in pieces, and the return visit completes it. That is the standard on any emergency locksmith too: nobody is left with a door that cannot lock.
Keying alike, and when not to
Most households in this part of 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 gate — all different, all on one ring, none labelled, and one of them tried in the dark before the right one.
A lock change is the natural moment to fix that, because the cylinders are being handled anyway and keying them alike costs very little extra at that point. One key opens every external door, the ring gets smaller, and nobody stands in the rain working through five options.
There is a trade-off worth stating rather than glossing over. One key for everything means one lost key affects everything, and anybody handed a key for one purpose can open all of it. Where somebody needs partial access — a gardener who should reach the store and not the house, a tenant in a cottage — the answer is a key hierarchy rather than keying everything alike.
What a complex or estate allows
A great many properties in the ring we cover sit inside developments that regulate anything visible from common property. Finish, style and sometimes brand are specified, and a few run their own restricted key system that each unit is expected to join.
Fitting first and asking afterwards is how people end up paying twice — once for the hardware and once for removing it. Ask the managing agent or estate office in writing before anything is ordered, and pass the answer on when you book, because it decides which cylinders can go in.
Where hardware is tightly regulated, re-pinning becomes considerably more attractive, since nothing visible changes at all. And the work that is never regulated is the work inside your own unit: a hookbolt on the slider, a reinforced strike plate, a better cylinder between the garage and the house. That is where most of the value sits in any case, and it falls under security lock upgrades.
The frame, which decides whether the new lock is worth anything
It is possible to fit an excellent cylinder to a door and improve nothing at all, and on the older housing stock around Bryanston it happens regularly.
Strike plates on doors of that age are frequently held by short screws biting into an architrave rather than reaching the structure behind it. Force going around a lock does not care what the lock cost, and a very good cylinder in a weak frame is bypassed entirely without anybody touching it.
So a lock change on an older door should include longer screws that reach the stud and, where it is warranted, a reinforced strike plate. It adds very little to the visit and it is the difference between a new lock and a genuinely better door. Anything found along the way that is worn rather than weak is lock repair in Bryanston instead.
What it costs, and when to book it
You are given a price band on the phone before anybody is dispatched, and it is confirmed on site against what is actually on the door. The band depends on how many doors, what grade of cylinder, and whether anything has to be ordered — which is why the description you give on the phone matters.
The hour matters too. A lock change is almost never an emergency, and doing it at a booked time on a weekday morning costs less than the same work at eleven at night. Where it genuinely is urgent — a door that will not lock, keys lost with an address attached, a lock that has been forced — it is handled at any hour and priced accordingly, and you hear the after-hours rate before a technician leaves.
Doing several small things in one visit is cheaper again, because the callout is shared between them. A change on two doors, a hookbolt on the slider and a look at the security gate is one morning rather than three. Tell us what you need on the locksmith booking line and the slot is held.
