Office parks, consulting rooms, retail and body corporates. The hardware matters, but what costs businesses money is almost always administrative: nobody can say who reaches which door. This page is largely about fixing that — and about doors that take several hundred operations a day rather than six.
Key control is the business problem, not the lock
Broken locks are easy. What costs businesses money is not knowing who holds a working key, and that problem accumulates quietly rather than arriving as an incident.
Write the list honestly: current staff, former staff, the cleaning company and whoever it has employed, contractors who finished a job, the landlord, the managing agent, and in many cases a previous tenant. Unless the premises run a restricted key profile, any one of those keys could have been copied at a hardware counter for small change, with no record and nobody's permission.
That is an administrative exposure with a hardware answer. Where every key opens everything and the list has drifted, a lock change resets it in a visit. Where different people legitimately need different doors, a master key system is the structure rather than a bigger bunch of keys.
Traffic is what wears a commercial door out
A domestic front door might be operated six times a day. A reception, a shopfront or a shared office entrance can be operated two hundred times a day, and the mechanism inside it wears at a completely different rate.
The failures follow from that rather than from age. Springs weaken until a latch stops throwing cleanly. Closers drift out of adjustment so the door either slams or fails to shut properly. Cams round off inside the case until the key turns and nothing happens. None of it is dramatic, and all of it surfaces at closing time on a Friday.
So a business entrance is a maintenance item, not something you replace when it dies. A scheduled look at the door, the closer, the alignment and the mechanism costs very little next to premises that cannot be locked at the end of the day, and it is ordinary lock repair work.
Out-of-hours installation is the normal arrangement
On business premises a lock change during trading hours is a disruption rather than an inconvenience. Reception cannot be left open, a door cannot be off its hinges while clients arrive, and ninety minutes of work can cost far more than ninety minutes of labour.
So installation is usually booked outside trading hours, and that is the ordinary way of doing it rather than a favour. It costs a little more in labour and a great deal less in interruption, which is the trade most owners make without hesitating once it is put to them in those terms.
The exception is a failure. A door that cannot be locked at close of business is an emergency at any hour: secured that evening so the premises are not standing open, then finished properly afterwards.
Load shedding, and the direction a door fails in
Anything electronic on a door in Johannesburg has to work through a scheduled outage, and the question is not whether the system has a battery. It is which way the door fails when the power drops, and whether anybody has actually decided.
Fail-secure keeps the door locked without power, which protects stock and requires a mechanical override so people inside are not trapped. Fail-safe releases the door, which protects people and leaves the premises open. Both are legitimate choices for different doors in the same building. Anything that genuinely cannot wait is handled as an emergency locksmith call, at any hour.
What is not legitimate is finding out during an outage. Every electronic installation should be handed over with that answer written down, along with where the override key lives — and it must not live inside the door it opens. That is covered in more depth under access control.
What a premises should be handed at the end of a job
A written record, and it matters more on business premises than anywhere else. Which doors were attended, what was done to each, how many keys were produced, and who holds every one of them.
That record is what makes the next conversation possible. When somebody leaves, it says which cylinders are affected. When a managing agent asks who can open the plant room, it answers with names. When a key cannot be accounted for, it turns an expensive guess into a decision about three doors rather than thirty.
It is also the thing most often skipped, because it is administration rather than hardware. For premises where more than a handful of people hold keys, it is worth formalising into a proper suite with a register, which is what master key systems are for.
Setting up before the first emergency
Three arrangements make every later call shorter, and all of them are easier to make on a Tuesday than at seven on a Friday evening.
Who in the organisation may instruct work on which doors, and how they are reached out of hours. Whether the building's security desk will admit a contractor after hours and what notice they need. And whether invoicing runs against an account or a purchase order, so a job is not held at the door by a payment question.
For premises where more than a handful of people hold keys, a register belongs alongside those three — which is what a properly specified master key system in Rivonia is really for.
Body corporates and managing agents
Managing agents and bodies corporate are a particular case, because the person instructing the work is rarely the person using the door, and the record matters as much as the job.
So the useful arrangement is agreed in advance: who may instruct work, how invoicing runs, and what documentation comes back afterwards — which doors were attended, what was done, how many keys were produced and who holds them.
For a development with communal doors, plant rooms and a rotating cast of contractors, that record is the entire difference between a key register and a drawer of keys. It is what a properly specified master key system in Sandton is built around.
What premises actually get called out for
Three things account for most of it, and none of them is a break-in.
A door that has stopped latching properly, usually because a closer has drifted or a hinge has dropped, discovered when somebody cannot lock up on a Friday evening. A staff change that has left nobody able to say how many working keys exist. And an entrance mechanism worn out by traffic rather than by age, which fails at closing time because that is when it is asked to do the thing it has been failing at all week.
All three are cheaper as maintenance than as emergencies, and all three are predictable. That is the argument for a scheduled look at the doors rather than a callout when one of them finally stops — the same case made under lock repair in Rivonia for houses.
Getting a straight quote for premises
Three things make a commercial quote comparable, and asking for them by name is worth doing.
What is being fitted and to which specification, rather than a product name alone. Whether the work includes the door, the closer and the alignment or only the lock, because a new cylinder on a door that will not latch solves nothing.
And when it will be done, because out-of-hours installation is the normal arrangement on trading premises and it should be priced in rather than added afterwards.
