Digital and smart locks in Rivonia
Smart locks are strong at a problem people usually name incorrectly. They are a key-management upgrade, not a security one. If the difficulty is letting a cleaner in on Tuesdays or granting a contractor access for a week, they solve it neatly. If the difficulty is a weak door, they do nothing about it at all.
Where they genuinely earn their place
Issuing and withdrawing access without physical keys. A code for a contractor that expires on Friday, a code for a house-sitter cancelled from your phone, access for staff without another key in circulation.
Most keep a log, so you know a door opened at 14:20 rather than guessing. For anyone letting a property or managing regular third-party access, that alone can justify fitting one.
Batteries, power and the override
A smart lock is a battery-powered device on the outside of a building. Batteries go flat, generally inconveniently, and the better models warn well in advance — check what that warning looks like before relying on it.
The mechanical override matters more here than anywhere. We fit smart locks with a physical key path wherever the hardware supports one, 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.
On commercial doors, think about scale
A standalone smart lock is a good answer for one or two doors. Past that, a proper access control system is usually cheaper to administer and far easier to audit, because credentials live in one place rather than in several apps.
If you are considering smart locks for several doors, it is worth comparing the two properly before committing — we will tell you honestly when access control is the better buy even though it is the larger job. Business premises are handled through our commercial locksmith work.

Fitting it so it lasts
Most smart lock disappointments are installation problems, not product problems. A motorised bolt fighting a door that has dropped drains batteries quickly and eventually fails outright.
We assess the door first and will say plainly if it needs adjustment beforehand. That is the difference between a lock that lasts and one that becomes a callout.
What they are genuinely good at
The honest case for a smart lock is access management rather than security, and on the right door that is worth real money.
A code or credential can be issued to a cleaner for Tuesday mornings and withdrawn on Wednesday. A contractor can be given access for the length of a job without anybody meeting them with a key. A short-let handover can happen with nobody present. None of that is possible with metal, because a key is permanent by nature and no amount of good intention makes it temporary.
So the question is not whether a smart lock beats a good cylinder. It is whether you have an access problem keys cannot solve. Where people come and go on a schedule the answer is frequently yes; where the same four people have used the same door for a decade it is almost always no.
The five questions to ask before buying
What happens when the battery dies — is there a mechanical override, and where does its key live? What happens during load shedding, and does this door fail locked or unlocked? Where the real question is how many keys exist, that is a lock change rather than anything more.
Is the mechanical part any good, because a smart lock is a motor attached to a lock and the lock underneath still has to be a proper one? Does it require an account and an app to function, and what happens to your door if that service is withdrawn in five years?
And is the manufacturer likely to still exist then? That last question sounds unfair and it is the one that most often turns out to matter, because a discontinued product with a dead app is a very expensive mechanical lock.
Complexes, and what you may actually fit
In a complex or a cluster the decision is not entirely yours. Most bodies corporate regulate anything visible from common property, and a smart lock is highly visible.
So approval is frequently needed, and trustees meet on a schedule rather than on demand — which means a question asked in October may be answered in November. Fine for planned work, useless in a hurry.
The tidier route in a regulated development is a product that retains the original cylinder as its mechanical override. The door still accepts a key, removal at handover is genuinely simple, and the appearance question becomes far easier to answer.
Where a smart lock is the wrong answer
On an outdoor gate in this climate. Anything electronic facing Highveld dust and summer storms lives a harder life than the manufacturer's testing assumed, and gates are operated far more often than front doors. Anything that genuinely cannot wait is handled as an emergency locksmith call, at any hour.
On a door whose underlying mechanism is worn, because a motor driving a failing lock fails faster than a hand does — that is a lock repair question first and an electronics question second.
On a door protecting something genuinely valuable, where a properly specified mechanical high-security cylinder still outperforms most consumer electronics. And on any door where nobody has decided who administers it, because a smart lock with three unrecorded administrators is a worse arrangement than a key register.
The hybrid most households should choose
For most homes the sensible answer is neither all-mechanical nor all-electronic.
Keep a properly specified mechanical lock on the main door, and put the electronic convenience where the access problem actually is — a pedestrian gate a service uses, an outbuilding a contractor needs, a garden gate. The door that matters is then unaffected by batteries, outages and subscriptions, and the doors people cycle through are easy to manage.
Where security rather than convenience is the goal, the same money spent on the frame, an anti-snap cylinder and a hookbolt on the patio slider does more. That is what the high security locks page covers, and it costs less than most smart locks.
Where these are worth fitting locally
Smart locks are installed across Rivonia and the Sandton suburbs around it, in Johannesburg, Gauteng, and the honest pattern is that they suit some situations here and not others.
They earn their place where people come and go on a schedule: a property with a cleaner on set days, a short-let unit, a home office that receives clients, an outbuilding a contractor needs for a fortnight.
They are a poor fit on outdoor gates in this climate, on doors whose underlying mechanism is worn, and in complexes where the body corporate regulates the appearance of a front door — which covers a good deal of Paulshof, Sunninghill and Bryanston.
What we will and will not fit
We fit products with a genuine mechanical override and a sound lock underneath, and we will say plainly when a product does not have one.
We will not fit a smart lock over a mechanism that is already failing, because a motor driving a worn lock fails faster than a hand does. That is a lock repair in Rivonia first, and then a conversation about electronics.
And in a regulated development we will ask whether the body corporate has approved it before anything is ordered, because a lock that has to come off again in March is an expensive way to learn what the rules were.
Living with one in this country
Two practical habits make the difference between a smart lock that works for years and one that becomes a problem.
Replace the batteries on a schedule rather than when it warns you, because a warning at the wrong moment is a lockout, and keep a spare set somewhere that is not behind the door in question. Test the mechanical override twice a year, because an override nobody has used is an assumption rather than a fallback.
And keep the mechanical lock underneath it maintained like any other lock. That is the part that still works during an outage, after a firmware problem, and in ten years when the app has been discontinued — which is exactly why it should be a proper lock rather than whatever was already on the door.
What we tell people who ask about them
The honest answer is usually a question back: what problem are you solving?
If it is access management — a cleaner on set days, a contractor for a fortnight, a short-let handover — a smart lock genuinely solves something keys cannot, and it is worth the running cost. Where different people need different doors, the answer is a master key system rather than more keys.
If it is security, the same money spent on the frame, an anti-snap cylinder measured to sit flush, and a hookbolt on the patio slider does considerably more. That is not a sales position; it is where the evidence sits, and it is set out under high security locks in Rivonia.

Digital & Smart Locks — common questions
Will you service the mechanical lock underneath?
Yes, and it should be part of the same visit. That lock is the fallback during an outage and after a firmware problem, so it wants maintaining like any other lock rather than being forgotten.
Can you fit a lock I have already bought?
Usually, provided it has a genuine mechanical override and the door and existing mechanism are sound. Where a product has no override, that gets said before fitting rather than discovered when a battery dies.
Do they work during load shedding?
The lock itself runs on its own batteries, so it keeps working. What may not is anything depending on wifi or a hub, which is why the mechanical override matters and why its key must live outside the door it opens.
Are they suitable for a rented property?
Only with the landlord's agreement, and in a complex the body corporate's as well. A product that keeps the original cylinder as its override is far easier to get approved and far easier to remove at the end of a tenancy.
Are smart locks secure enough for a front door?
The better ones are, provided the mechanical lock underneath is a proper one and the installation is sound. The real question is different: a smart lock solves access management, not resistance to force, and if force is your concern the frame and an anti-snap cylinder matter more.
What happens when the battery dies?
On a well-chosen product, a mechanical override key opens the door and the battery is replaced. On a poorly chosen one, you are locked out of your own house. That is why the override and where its key lives are the first questions to ask, not the last.
Can I fit one in a complex?
Ask the managing agent first. Anything visible from common property is usually regulated, and a smart lock is visible. A product that keeps the original cylinder as its override is far easier to get approved and far easier to remove later.
Are they a good idea on a gate?
Generally not here. Outdoor electronics face Highveld dust and summer storms, and gates are operated far more often than front doors. A sound mechanical gate lock, cleaned and lubricated once a year, is the more dependable arrangement.
What if the manufacturer stops supporting the app?
Then you have a mechanical lock with a dead panel on it, which is why the override matters and why the choice of manufacturer matters. Products that keep a standard cylinder underneath fail gracefully; products that do not, do not.
What if the battery dies while I am out?
On a well-chosen lock, very little: it warns 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 smart locks more secure?
Not automatically. They are better at controlling and recording access. Physical resistance still comes from the bolt, the frame and the fixings, which is where we would look first.
We want them on six office doors.
At that number, access control is usually cheaper to administer and much easier to audit, because credentials sit in one system rather than several apps. Worth comparing properly before committing — we will give you a straight view even though it is the bigger job. On a house, all of this is ordinary residential locksmith work rather than a specialism.
Can we still use keys?
On most models we fit, yes, and we would recommend keeping that route serviceable. Locks with no mechanical path put every entry through the electronics.
