Lock Change in Randburg
Moved in? Lost your keys? Post break-in? We change locks across Randburg the same day, with brands we trust.
A lock change is the single fastest way to reset who has access to your property. Whether it's one cylinder or every external door in a five-bedroom house, we quote clearly, fit properly and hand you a matching set of keys before we leave.
When to Change Your Locks
Locks are wear parts — they don't last forever, and life events reset who should hold a key. Change your locks after moving in, losing keys, a break-in, a tenant leaving, a divorce, a domestic worker changeover, or if the key ever feels sticky or 'wobbly' in the cylinder.
Residential Lock Changes
Front doors, back doors, patio sliders, security gates, garage side-doors — we handle the lot, and we stock enough hardware in-vehicle to complete most homes in a single visit.
Commercial Lock Changes
Offices, shops, warehouses and body-corporates. We can also fold the change into a master-key system so you end up better organised than you started.
Security Gate Lock Changes
The Xpanda or Trellidor at your front door is your true perimeter. We replace tired padlocks and slam-lock cylinders with hardened, weatherproof units — anti-cut, anti-drill, and rated for outdoor life in Highveld weather.
Garage Door Lock Changes
Roll-up, sectional and tip-up garage doors all use different lock hardware. We match the right unit to your door type and, where possible, key it alike with your house locks so you carry fewer keys.
Lock Brands We Fit
We work with the established brands you'd expect — Union, Yale, CISA, Assa Abloy, Mul-T-Lock and select smart-lock brands. We do not fit budget locks from anonymous importers.
What a lock change costs in Randburg
A lock change is priced per lock, so the biggest factor is simply how many doors and gates you're doing. One front-door cylinder is a small job; every external door and security gate in a five-bedroom house is a half-day. The second factor is what you fit: a like-for-like standard cylinder is the entry point, while an anti-snap, anti-bump high-security lock costs more but is far harder to defeat.
There's often a cheaper middle path. If your existing locks are in good condition and you just need the old keys to stop working — after a tenant leaves, say — we can sometimes re-pin the cylinders instead of replacing them, which saves on hardware. We'll always show you both options and a written price before we start. If you're not sure whether the lock even needs changing, our lock repair team can assess it first.
Signs it's time to change the locks — not just repair them
Some situations call for a clean break rather than a fix. Change the locks when you've just moved into a new home and don't know who still holds keys; after you've lost a bunch of keys; after a break-in or attempted forced entry; when a tenant, domestic worker or contractor with access moves on; or after a divorce or dispute where someone shouldn't keep a key.
But not every problem needs a whole new lock. A key that sticks, a bolt that's stiff, or a handle that's gone loose is often a repair, not a replacement — the guide on how to tell if your lock needs replacing walks through the difference. If it turns out to be wear rather than a security concern, a lock repair is the cheaper, sensible call.
Lock changes across Randburg's suburbs
Move-in lock changes are our bread and butter in fast-turnover family suburbs like Randpark Ridge and Fourways, where new owners want every door done on collection day. In the walled estates and complexes around Bryanston and Dainfern, we handle bulk cylinder swaps and staff-access separation as part of a wider home security plan.
On the hillside homes of Northcliff, the priority is usually the security gate and pedestrian gate — the real perimeter — where we fit hardened, weatherproof cylinders built for Highveld weather. And for the shopfronts along Parkhurst's 4th Avenue or Ferndale's Oak Avenue, a lock change often folds into a commercial security upgrade.
Change or repair — how to tell which you need
The two jobs get confused constantly, and the distinction is simple once it is said out loud. A change is about who can open the door. A repair is about whether the door works. If the mechanism is sound and you simply do not know how many keys exist, you need a change. If the mechanism is deteriorating and the number of keys is not in question, you need a lock repair. Quite often people are quoted for one when the other was the actual problem.
The test that separates them is whether anything is physically wrong. A cylinder that turns cleanly, latches properly and has never given trouble does not need replacing because the household has changed — the mechanism is fine and only the keying is at issue. Conversely a mechanism that has needed a lift for a year will still need that lift after a change of keys, because nothing about the fault has been addressed by giving it a new set. Where this page is the considered account of changing who can open a door, locksmith near me is the version written for the pavement.
Where both apply — an old mechanism and an unknown number of keys — a change deals with the pair of them at once and is the better value of the two. That is the usual situation after a purchase on an older property, which is why the standard advice on moving in is a change rather than a service. It is also why a good quote will say plainly which of the two it is charging you for. The related reading is the first week in a new home, which goes further into the detail.
The moments that genuinely warrant a change
Transfer is the first and the least disputed. Every sale hands the same keys along, no private house keeps a register, and by the time a property has changed hands twice the true number in existence is unknown to everybody involved. Nobody in the transaction has any duty to deal with it. Doing it in the first week costs very little and converts a permanent unknown into a number you chose, which is the whole point.
The end of a tenancy is the second, and it is worth treating as routine rather than as an event — in the way a property gets cleaned between occupants. A house that has been let three or four times without a reset has passed one set of keys down a chain of people, none of whom owed anything to whoever came next. That is not a scandal; it is simply an unknown, and unknowns are what make the question awkward later.
The third group is everything that changes who should have access: a lost bunch of keys, building work finishing, a domestic arrangement changing, a staff change on a business premises, a key that went out years ago for a reason that has long since ended. In every one of those cases a change is easier than a conversation and says nothing about anybody. Households across Melville and Parktown North deal with this constantly.
Who needs a lock change in Randburg
Four moments, and none of them require anything to be broken.
The household that has just transferred
Keys travel with a property through every previous sale, and no register has ever existed. Nobody in the transaction has any duty to deal with it, which is exactly why it falls to the new owner.
The landlord between tenancies
The property is empty, nothing has to be arranged around anybody, and the whole job is one short visit. It is the cheapest and least disruptive moment in the entire cycle.
The business after a staff change
Somebody has left and a key did not come back. Changing the affected cylinder says nothing about the person and restores a number the business chose.
The household with a key out there somewhere
A builder, a former tenant, a relative, a service that ended years ago. Nobody wants the conversation, and a change removes the need for one.
What moves the price on a lock change
The number of openings decides most of it, and the honest list is usually shorter than expected. What matters is every opening somebody could reach from outside without climbing — typically the front door, a back or side entrance, a garage door and a boundary gate. Doing those together in one visit costs meaningfully less per opening than the same work spread over years.
The second is whether the doors themselves are sound. A cylinder swap on a door that hangs square is quick; the same swap on a door that has dropped, or with a keeper fixed into soft timber, needs the surrounding work done first or the new lock will behave exactly like the old one. That is established before quoting rather than discovered afterwards.
The third is whether you want one key or several. Keying the reachable openings alike is usually the sensible choice and costs no more, while keeping a flatlet, a store or a garage separate is a deliberate decision worth making at the time rather than by default. For a different angle on this, the piece on letting a property and its locks is worth a few minutes.
Three things people get wrong about changing locks
Two are about doing too much and one is about doing it too late.
Changing every lock in the house
Internal doors and upstairs windows nobody can reach do not need work. The reachable openings are the job, and that is a shorter and cheaper list than most quotes assume.
Changing a lock to cure a sticking door
New keys do not fix a mechanism that has been asking for a lift, and they do not fix a door that has moved. That is a repair, and it is a different visit.
Waiting for a reason
Nothing has to have gone wrong. The point of a change at transfer or at a tenancy end is to convert an unknowable number into one somebody chose.
How a lock change runs
Straightforward work, and the decisions all happen before it starts.
Established by walking the outside rather than from a list over the phone. It is usually two or three, and occasionally one.
Hang, frame and keeper looked at first, because a new cylinder on a dropped door repeats the old behaviour within a fortnight.
One key for the doors you use, with anything that should stay separate — a flatlet, a store — kept separate deliberately.
A known number of keys issued and written down, so the figure is one you chose rather than one that accumulated.

We check door type, condition and count how many cylinders are involved.
Standard replacement, high-security upgrade or master-keyed set — you pick.
