Houses, clusters and townhouse complexes, and the everyday hardware that eventually stops cooperating: locks, security gates, gate motors. Most of this work is planned rather than urgent, which means it can be booked properly — and it is considerably cheaper than the version where you wait for something to fail.
Most homes here were not secured all at once
A house in this part of Sandton, in northern Johannesburg, Gauteng, has usually been secured in stages across decades. A steel security gate in one era, a better front-door cylinder after something happened nearby, a motorised driveway gate when the paving was redone, a slam-lock on a back door at some point nobody remembers.
Each of those decisions made sense on its own day. Together they produce a property with five or six locking points that have nothing in common — different brands, different key profiles, different ages, and a key ring nobody can fully identify.
That matters because failure is not evenly distributed. The oldest item fails first, and it is rarely the front door, because the front door is where the money went. It is the security gate, the back door or the outbuilding, and those are exactly the ones nobody inspects.
The Highveld is what actually breaks outdoor hardware
Anything facing the weather here goes through the same annual cycle. Dust from August through to the rains, then storms that wash that dust into every keyway, then a long dry winter that sets it into a paste which grinds the mechanism every time a key turns.
That is why a security gate lock and a driveway gate seize while the front door of the same house works perfectly. It is not that the outdoor hardware is worse; it is in a far harder environment and it is the piece nobody thinks to maintain.
So the honest maintenance advice for a house here is short. Once a year, try every external lock including the ones nobody uses, and lubricate what is stiffening with a proper lock lubricant rather than a general-purpose spray, which attracts more dust than it displaces. What that turns up is nearly always a lock repair in Rivonia rather than a replacement.
Gate motors, and the fault everybody misdiagnoses
A driveway gate that has stopped is blamed on the motor almost every time, and the motor is usually innocent. Motors are strong; tracks, rollers and the alignment of a heavy gate are not, so the mechanical side gives out first and the electronics fail trying to overcome it.
There is a two-minute test that settles it before anybody drives out. Put the motor on manual release and push the gate by hand along its track. If it rolls freely, the fault is electrical. If it drags, grinds or catches at a particular point, the fault is mechanical and the motor has been straining against that resistance for months.
Note also whether it has been slowing gradually over a season or stopped suddenly overnight, because those point in different directions too. Four observations, two minutes, and the difference between one visit and two.
Where the money is best spent on a house
The sensible order is shorter than most people expect and it is rarely what gets quoted. The frame first, because a superb cylinder held by screws that reach only the architrave is bypassed by force going around it rather than through it. A reinforced strike plate with long screws into the structure costs very little and matters more than the lock does. If you are shut out while reading this, it is a house lockout and it is worth phoning rather than reading.
Then the main entrance cylinder. Then any door facing the garden or a boundary rather than the street, because on a property with mature planting that is where the exposure actually is. Then the patio slider, where a standard latch is a convenience catch rather than a lock and a hookbolt turns it into a genuine obstacle.
Then the outbuildings, which are cheap to improve because the doors are simple. And only then anything electronic. On most properties that is three or four items dominated by labour rather than hardware, and anything beyond it wants a specific reason — which is what the high security locks page is for.
The annual walk that prevents most callouts
Once a year, take every key you hold and try every external lock on the property, including the ones nobody uses. The gate onto the servitude, the store room, the garage side door, the padlock on the garden gate.
It takes half an hour on a large stand and ten minutes on a small one, and it converts an unknown into a list. What it finds is nearly always the same handful of things: a seized lock on a gate nobody opens, a slider with a convenience catch rather than a hookbolt, a strike plate held by screws reaching nothing but architrave, and an outbuilding wearing a cylinder that came off the front door a decade ago.
Then book one visit rather than four callouts. The callout is the fixed cost of any attendance, so bundling is where the saving is, and none of that list is urgent until the night it becomes an emergency locksmith call instead.
What a household should keep written down
Two things, and neither takes more than ten minutes. How many working keys exist for each external door and who holds each one. And who to call at two in the morning, stored in a phone rather than on a note inside the house.
The key count is the one nobody has. After a purchase, a tenancy, a change of domestic staff or a contractor finishing, the number becomes unknown — and an unknown number of working keys is the actual exposure on most properties, rather than the strength of any lock.
It is settled by a cylinder change and a note on a page, and it is far cheaper to deal with on a quiet weekday than in the week after something has happened.
What a homeowner should expect on the invoice
The figure quoted before work started, and nothing added afterwards without a conversation first. Where something is found on site that changes the price — a mechanism worse than it looked, a frame that needs reinforcing — that is explained before the work rather than after it.
An itemised description of what was actually done and what was fitted, which matters for insurance and for knowing in two years what is on your door.
And a count of the keys produced, with a note of who holds each one. That last item is the one nobody asks for and the one that answers the question honestly next time, which is the whole argument on the lock change in Rivonia page.
The three calls we take most often
A door pulled shut with the keys inside, usually while carrying something to the car, and usually opened without damage unless somebody has attacked it with a screwdriver first.
A security gate or driveway gate that has seized after a Highveld summer, which is grit rather than wear and is a service rather than a replacement if it is caught while the key still turns.
And a property that has just changed hands, where nobody can say how many keys exist. That third one is not a failure at all — it is the moment when a lock change in Sandton is genuinely worth the money, and it is the cheapest of the three to deal with.
