Digital and smart locks in Fourways
Smart locks are very good at a problem people usually describe wrongly. They are a key-management upgrade rather than a security one. If your difficulty is letting a cleaner in on Tuesdays or a guest arrive after you are asleep, they solve it elegantly. If your difficulty is a weak door, they do nothing whatsoever about it, and what you actually want is a high security lock.
What they genuinely do well
Granting and withdrawing access without physical keys. A code for a contractor that expires on Friday, a code for a house-sitter you cancel from your phone, entry for family who lose things — real problems, neatly handled.
Most keep a log too, so you know the back door opened at 14:20 rather than guessing. For anyone letting a property or managing regular access by other people, that alone can justify fitting one.
Batteries, power and the override
A smart lock is a battery-powered device sitting on the outside of your house. Batteries go flat, generally at an inconvenient moment, and the better ones warn you well in advance — check what that warning actually looks like before relying on it.
The mechanical override matters more here than anywhere else. We fit smart locks with a physical key path wherever the hardware allows, because a lock whose only route in is electronic is a lockout waiting for a flat battery. Anything mains-dependent needs its outage behaviour understood before it goes on the door. Tag and code entry is covered under access control.
Estates and approval
Estates and complexes across Johannesburg commonly regulate what may be fitted to an external door — which is one reason rekeying in Fourways is so often the easier answer — and a smart lock changes the appearance of one considerably. Check before buying rather than after fitting.
Some developments also integrate door access with the estate's own system, in which case a standalone smart lock may duplicate or conflict with what is already there. The estate office is the right first call.

Fitting it so it lasts
Most smart lock disappointments are installation problems rather than product problems. A motorised bolt fighting a door that has dropped will drain batteries quickly and eventually fail outright, so the door has to be right before the lock goes on.
We assess the door first and will say plainly if it needs adjustment beforehand. That is not an upsell — it is the difference between a lock that lasts and one that becomes a callout.
What they genuinely solve
The useful way to think about a smart lock is that it is a key-management device rather than a security device, and almost every disappointment comes from buying it as the second thing.
What it does well is remove physical keys from circulation. A cleaner who comes on Tuesdays gets a code rather than a key, withdrawn the afternoon the arrangement ends. A guest arriving after you are asleep lets themselves in without a key hidden under anything. A family stops cutting spares for teenagers who lose them.
That is a real problem and worth solving, particularly in a part of Johannesburg with as much domestic help, contracting and short-term letting as this one. It is the same problem a master key system solves for a business, arrived at from a different direction.
Batteries, outages and the way in
Every smart lock runs on batteries and every one will eventually be flat. That is a maintenance item rather than a defect, and the entire question is what the building does on the day it happens.
Good units warn for weeks and most take an external power bank at the door. Grid outages are a separate problem, because anything relying on wifi or a hub loses its remote functions during an outage even if the lock itself still runs — and across Gauteng that is routine rather than rare.
Which is why we fit hybrids without exception. There should be a mechanical cylinder on the door, or another door, opening with a key held by somebody reachable. A smart lock as the only way in is why a family sits outside during a long outage, and it turns a maintenance item into an emergency locksmith callout.
Where they are weaker than people assume
Three limitations come up often enough to state plainly, because they are rarely on the packaging.
The first is that a smart lock does nothing about a weak door. Electronics on a frame held by short screws into an architrave is a very modern way of securing nothing, and force going around a lock does not care what the lock is. The frame comes first, which is the argument on the high security locks page.
The second is alignment. Motorised bolts have far less mechanical sympathy than a hand and a key: where a person would lift a handle slightly, a motor simply stalls. The third is that they are outdoor-adjacent electronics in Highveld dust and summer storms, and they want a door that is actually sheltered.
Fitting one properly on an estate door
The installation matters more than the model, and the sequence is the opposite of what most people expect. The door comes first, then the frame, then the lock.
Before anything is fitted, the door should hang square, the bolt should throw freely into its keeper with no lifting or leaning, and the strike should be reinforced with screws reaching structure. On a door that has dropped, that is frequently a morning's work in its own right, and skipping it is why so many smart locks are described as unreliable.
There is an estate-specific step too: check what the development permits before buying. A smart lock is very visible, and estate rules and your front door covers what is usually allowed and what is not.
Codes, guests and the discipline nobody keeps
The benefit of a smart lock is that access can be given and taken away without metal changing hands. That benefit only survives if somebody actually takes it away, and this is where most installations quietly stop working.
A code issued to a cleaner three years ago that nobody has changed is not better than a key — it is a key that also cannot be counted. The same applies to a code shared between two people, one written inside a cupboard door, and the one everybody in the family gave to a friend once.
The discipline is small and it is the whole of the value: one code per person, withdrawn on the day the arrangement ends rather than at some later review, and the master code changed on a schedule. It is the discipline a master key system in Fourways imposes on a business, and no more onerous.
What to check before buying one
Most of what separates a good outcome from a bad one is decided before anything is ordered, and none of it requires technical knowledge.
Check the unit keeps a mechanical override, and that the override is a decent cylinder rather than a token one — an excellent smart lock with a cheap key barrel is exactly as strong as the cheap barrel. Check it suits the door you have, because a multipoint mechanism and a single deadbolt want different units. Check what happens on a flat battery.
Then check the thing people never check, which is whether the door hangs square. On any door that has moved, a motor has none of the sympathy a hand has. That is lock repair before it is an installation, and it is the commonest reason these are later called unreliable.
Which doors are worth it, and which are not
A smart lock earns its cost on a busy door with changing users, and almost nowhere else. The front door of a family home where four people come and go and two of them lose keys is the classic case.
It is also strong on a cottage, a garden flat or a short-let unit, where access has to be handed over repeatedly to people you may never meet. In those situations the alternative is either a key under a pot, which is worse than no lock at all, or somebody driving across Johannesburg to hand over a key.
It is not worth it on a back door nobody uses, on an outbuilding, or on any door where the answer is really that the frame is weak. Nor is it a substitute for rekeying after a move, because a new smart lock on one door does nothing about the old keys for the other three.

The installation matters more than the model, and the sequence is the opposite of what most people expect. The door comes first, then the frame, then the lock.

On a door that has dropped, that is frequently a morning's work in its own right, and skipping it is why so many smart locks are later described as unreliable.
There is an estate-specific step too: check what the development permits before buying, because a smart lock is very visible. Where it is not permitted, rekeying in Johannesburg gets you the security half without altering anything visible.

Digital & Smart Locks — common questions
What happens when the battery dies?
Most units warn for weeks and many take an external power bank at the door. The real answer is that there should always be a mechanical way in — a cylinder on that door or another with a key held by somebody reachable. We fit hybrids for exactly this reason.
Will it still work during load shedding?
The lock itself will, because it runs on its own batteries. Anything depending on wifi or a hub — remote unlocking, notifications, granting a code from elsewhere — stops until the power returns. That is worth knowing before relying on it to let somebody in while you are out.
Are smart locks less secure than a normal lock?
Not inherently, and it is the wrong question. They address key management rather than resistance. A smart lock on a weak door is a weak door. A good cylinder in a reinforced frame with a smart unit added is a well-secured door that is also convenient.
Can you fit one to my existing door?
Usually, though the door has to be right first. It should hang square, the bolt should throw freely without lifting, and the strike should be properly fixed. On a door that has dropped that is often a morning's work before installation, and skipping it is the commonest reason a smart lock is later called unreliable.
Will our estate allow one?
Ask the estate office first, because anything visible on a door facing common property is frequently regulated. Where it is not permitted, rekeying in Gauteng achieves the main security benefit — old keys stop working — without altering anything visible.
What if the battery dies while I am out?
On a well-chosen lock, very little happens: it warns you for weeks beforehand and there is a mechanical key path as backup. We fit models with a physical override precisely so a flat battery is an annoyance rather than a lockout.
Are they more secure than a normal lock?
Not automatically. They are better at controlling and recording access. Resistance to someone physically attacking the door still comes from the bolt, the frame and the fixings.
Will my estate let me fit one?
Worth checking before you buy. Many estates and complexes regulate external hardware, and some integrate door access with their own system, where a standalone smart lock may conflict with what is already in place.
Can I still use a physical key?
On most models we fit, yes, and we would recommend keeping that route serviceable. Locks with no mechanical path put every single entry through the electronics.
