Broken key extraction in Rivonia
A key snaps because it has been flexing against a stiff lock for months and finally gave out. The broken half can usually be drawn straight back out and the cylinder carries on working — provided nobody spends the next twenty minutes making it worse.
Do nothing, deliberately
The most common way an easy extraction becomes a difficult one is somebody pushing the fragment deeper with a screwdriver, a paperclip, a hairpin or the other half of the key. Once it is past the mouth of the plug there is much less to catch.
Skip the lubricant as well. Oil makes the fragment slippery against extraction tools and gathers dust into paste. If enough of the key protrudes to grip properly, pull it straight out without twisting. If it sits flush or inside, leave it and phone.
How the fragment comes out
Extraction tools are slim hooks and fine saw-toothed blades that slide into the keyway beside the broken piece, catch on a cut edge and draw it back out. Delicate rather than forceful, and the cylinder is normally unmarked afterwards.
The plug generally has to be returned to its neutral position first, which is exactly why turning the broken half in the lock makes the job harder rather than easier. That job is broken key extraction, and it is usually non-destructive.
On business premises, look at the whole door
A key that snaps in a commercial entrance is rarely an isolated event. High-traffic doors wear their cylinders faster, and if one key has failed the others in circulation have been through the same mechanism.
Having the lock cleaned and adjusted while the technician is there is the difference between one incident and three over the coming months. For premises rather than homes, this falls under commercial locksmith services in the area.

Why the fragment is stuck, and why force makes it worse
The broken piece sits in the keyway with its cuts still holding the pins at their split points, and the plug has usually been left rotated part-way, which traps the fragment against the housing.
Returning the plug to neutral is most of the skill in the job, and it is exactly what pushing or twisting prevents. Every attempt to force the piece rotates the plug further or drives the fragment deeper, and both make the same job longer.
Pliers add a second problem. They push the piece past the point where a hooked extractor can catch its cuts, and they score the plug on the way in. That is how a twenty-minute extraction becomes a lock change, and it happens before anybody arrives.
What the snap actually tells you about the lock
A key almost never breaks because it was weak. It breaks because it was being asked to turn a mechanism that had become stiff enough to require force, and metal fatigue does the rest at the shoulder where the blade is thinnest.
So the snap is the end of a process rather than an event. The cylinder has been stiffening for weeks or months and the key has been taking more torque each time. That is why extraction is frequently only half the job: get the fragment out of a cylinder that is still seized and the next key will snap in it inside a month.
On outdoor hardware — security gates, driveway gates, garage side doors — the cause is nearly always grit rather than wear, and that is dealt with in the same visit as a lock repair rather than booked separately.
The Highveld does this to outdoor locks every year
Dust through the dry months works into the keyway. Summer storms wash it deeper. A dry winter sets it into a paste that grinds the wards on every turn.
Nothing about that is unusual and all of it is preventable. Once a year, work every outdoor lock on the property, and lubricate anything that has begun to stiffen with a proper lock lubricant — not a general-purpose spray, which flushes the grit temporarily and then attracts more dust than the lock had before.
That single habit removes most snapped keys around Sandton. The rest are keys that were already worn thin, which is a different problem with the same answer: replace the key before it replaces itself.
How the extraction runs
The plug is returned to neutral first, because a rotated plug traps the fragment. Then the piece is drawn out with an extractor that catches the cuts, working with the pins rather than against them.
Most extractions are non-destructive and the lock is left working afterwards. Where somebody has already forced the fragment deeper, or the plug itself has been damaged, drilling is occasionally the only route left — and that is explained first, with the cost of making good.
Then the cause is dealt with: a clean, a proper lubricant, an alignment check, and a straight answer about whether the cylinder is worn enough to be worth replacing while a technician is already there. Anything that genuinely cannot wait is handled as an emergency locksmith call, at any hour.
What to do in the meantime
Nothing to the lock, which is the hardest instruction on this page to follow.
Do not push the fragment, do not turn it, do not reach for pliers, and do not try the spare key — a second key forced into a keyway that already holds half of the first damages both. If a piece is protruding and comes away between two fingers with no force at all, that is fine; anything requiring effort is not.
Meanwhile check whether there is another way into the property, because a key snapped in a security gate does not always mean you are shut out. And if somebody is shut inside, say so when you phone, because that changes the priority rather than the method.
Where extractions come from
Snapped keys come in from across Rivonia and the Sandton suburbs around it, in Johannesburg, Gauteng, and the pattern is remarkably consistent: outdoor hardware, at the end of a dry winter, on a lock that had been stiffening since the previous summer.
Security gates account for most of them. Driveway gates and garage side doors account for most of the rest. Front doors are a distant third, because they are sheltered and because they are the lock people notice.
That geography is useful, because it means the fix is predictable. Deal with the outdoor locks once a year and the snapped key largely stops happening, which is ordinary lock repair in Rivonia rather than anything specialised.
What it costs, and what makes it cost more
An extraction from an undamaged cylinder is a short job and it is quoted before a vehicle moves. What changes the number is what happened first.
Pliers push the fragment deeper and score the plug. A second key forced into a keyway that already holds half of the first damages both. Either can turn a twenty-minute extraction into a lock change in Rivonia, and both happen in the minutes before anybody arrives.
The hour matters too. If the property is otherwise accessible — a snapped key in a store room or an outbuilding while the house is open — a booked weekday visit costs meaningfully less than a callout tonight, and you will be told so rather than sold the callout.
What happens to the rest of your keys
A snapped key raises a question nobody asks in the moment: how old is the rest of the set, and are they wearing the same way?
Keys cut from a worn duplicate rather than from an original are already imprecise, and every copy after that is worse. A set that has been through fifteen years and three generations of copying is a set that will keep breaking regardless of the lock.
So while a cylinder is open and working properly, it is worth cutting a fresh set from a key that fits well, and knowing how many exist. That is a small job on the back of an extraction, and it is the same count that matters after a lock change in Sandton.
Padlocks, gates and the ones people forget
Snapped keys are not only a front-door event, and the ones on outbuildings frequently go unreported for weeks.
A padlock on a garden gate, a store room, a garage side door: a key breaks, the door is simply not used, and the problem is left. That is a security gap rather than an inconvenience, because a padlock with half a key in it is neither locked properly nor openable in a hurry.
It is also a cheap fix when done alongside other work rather than as its own callout. Anything on an outbuilding or a boundary gate belongs on the annual walk-round described under residential locksmith.

Broken Key Extraction — common questions
Can you attend the same day?
Almost always, and immediately where you are shut out or the property cannot be secured. Where the door is on an outbuilding and the house is open, a booked morning visit costs less.
How quickly can you attend?
It is treated as urgent where you are shut out or the property cannot be secured, and as booked work where the door is on an outbuilding and the house is open. You will be told which of the two applies rather than sold a callout at a premium.
Can you cut a replacement key on site?
A replacement for a standard door key is normally straightforward once the cylinder is working again. Vehicle keys are not offered at all — no cutting and no programming — and you are told that on the phone rather than after a callout.
Is a snapped key covered by insurance?
That depends entirely on the policy, and it is worth asking rather than assuming. What helps either way is an itemised invoice describing the work, which is issued as a matter of course.
Can the key be removed without damaging the lock?
In most cases yes. Extraction tools catch the cuts on the broken piece and draw it out with the plug returned to neutral, leaving the lock working afterwards. What makes that impossible is usually an earlier attempt with pliers that has pushed the fragment deeper or scored the plug. If you are shut out while reading this, it is a house lockout and it is worth phoning rather than reading.
My key snapped in the security gate. Why did that happen?
Because the lock had stiffened and the key was taking more force than it was designed for. Outdoor locks here fill with dust and grit through summer and set hard in winter, and the snap is the last stage of a process that has been running for months.
Will I need a new lock afterwards?
Not usually, if nobody has forced it. What often is needed is dealing with the reason it snapped — a strip, a clean and a lubricant — because a fragment removed from a seized cylinder simply means the next key snaps in it too.
Can I try to get it out myself first?
Only if a piece is protruding far enough to come away between two fingers with no force at all. Anything beyond that pushes the fragment deeper past the point an extractor can reach, which is what turns a short job into a much longer one.
Do you carry replacement cylinders?
Yes, the common types used across homes and business premises in this area, so a cylinder that genuinely is finished can usually be replaced on the same visit rather than needing a second callout.
Will you have to drill it?
Usually not. Most broken keys come out with extraction tools and the cylinder survives. Drilling is kept for fragments jammed beyond reach or locks already damaged, and you would be told first. Where the hardware itself needs improving, that sits under high security locks.
Part of the key is showing. Should I pull it?
If you can grip it firmly, pull straight out with no twisting. If it slips or you find yourself reaching for pliers, stop — a fragment dragged sideways can jam in the plug and turn a simple job into a hard one.
Will the lock work afterwards?
Normally yes. But if the key broke because the lock was stiff, that stiffness remains and the next key will eventually do the same. Worth dealing with while someone is already there.
