Lost your keys in Rivonia?
Losing keys is two problems in one. Getting back inside is straightforward. The second problem — that a working set of keys is somewhere unaccounted for — does not resolve itself when the door opens, and for business premises it is considerably the larger of the two.
Getting you in
A technician opens the door without damage wherever the lock allows, after confirming you have the right to be there. That check is the whole difference between a locksmith service and something else, so it is not one we skip.
For a home, a bill or lease for the address, identification, or a neighbour who can vouch for you. For business premises, a letterhead with matching identification, a lease, or confirmation from the building's managing agent.
Business keys are a different order of problem
A lost house key is one door. A lost set from an office can cover a main entrance, internal doors, a store room and sometimes a shared building entrance used by other tenants.
If a master key is among them, the exposure runs well beyond your own suite, and the managing agent needs telling immediately — not because of protocol but because other tenants' doors may be affected. For premises rather than homes, this falls under commercial locksmith services in the area.
Deciding what to do next
If keys vanished anonymously with nothing identifying them, the practical risk is modest. If they went with a bag containing your address, or from a car outside the premises, it is not.
Changing the cylinder is usually proportionate: locks stay, pins change, the missing set becomes scrap. Replacement makes sense where hardware was due an upgrade anyway. And do not stop at the obvious door — back entrances, gates and outbuildings were probably on the same ring.

The first question is not what you lost, it is what was on the ring
Keys lost anonymously and keys lost with your address attached are two completely different situations, and the response should be different too.
If a set went missing in a shopping centre with nothing on it identifying where it fits, the finder has metal and no idea what it opens. That is inconvenient rather than urgent, and it can be dealt with at your convenience during weekday hours.
If the ring carried a car remote, an access tag for a complex, a labelled fob, a business card or anything else that points at an address, treat it as urgent. Somebody now has a working key and knows where to use it, and that is a same-day lock change rather than a decision to sleep on.
Do not stop at the obvious door
The mistake people make is replacing the front door cylinder and considering the matter closed. A house key ring almost never carries only a house key.
Think about what else was on it: the back door, the security gate, the garage side door, a store room, an outbuilding, a padlock on a garden gate, a complex pedestrian gate, an office. Any of those still works, and the outbuilding is frequently the one that contains a ladder.
Write the list before anything is quoted. It is the cheapest part of the job and it is what stops the same conversation happening again in three weeks when somebody remembers the store room.
Access tags, remotes and things that are not keys
A modern key ring carries more than metal. A complex access tag, a gate remote, a building fob and sometimes a vehicle remote.
Tags and fobs can usually be deactivated by the managing agent or the security company, which is faster and cheaper than anything a locksmith does — and it should be the first phone call rather than the second. A gate remote generally cannot be deactivated individually on older systems, which may mean re-coding the receiver.
None of that is our work, and saying so is more useful than pretending otherwise. Deal with the electronics through whoever administers them, and deal with the mechanical locks separately. Where the fault turns out to be mechanical, it is dealt with as a lock repair.
What it actually costs, and how to keep it down
Changing the cylinder on each affected door is the standard answer, and it is far cheaper than replacing locksets. The hardware stays; only the part that decides which key works is swapped.
Doing all the affected doors in one visit is the significant saving, because the callout is shared. Doing them across three separate calls costs a great deal more for exactly the same work.
And this is the natural moment to key alike if you want to — the cylinders are open anyway, so matching the front door, back door and gate to a single key costs very little extra. The trade-off is that one lost key then affects everything, which is worth thinking about while you are already thinking about lost keys.
Afterwards: the count that prevents the next one
When the new keys are handed over, write down how many were produced and who holds each one. It takes a minute and it is the only thing that answers the question honestly next time.
For a household that means knowing whether the spare with a neighbour is one of the new set or one of the old ones. For a business it means a register with a number against every key, which is what master key systems formalise.
The reason this matters is that "we changed the locks" is a statement about a day, not about a number. The count is what turns it into something you can still rely on in two years.
Where this is done, and how quickly
Cylinder changes after lost keys are done across Rivonia and the neighbouring Sandton suburbs of Johannesburg, Gauteng, and in the urgent version of this — keys gone with your address attached — it is treated as an emergency and attended the same day.
In the non-urgent version it is booked, and booking is the cheaper answer by a clear margin. Weekday daytime work costs less than an evening callout for exactly the same job on exactly the same doors.
The judgement between those two is made on the phone in about thirty seconds, and it turns on one question: was there anything on that ring that points at where the keys fit?
Getting the whole ring, not just the front door
The most common mistake is dealing with the front door and considering it closed. Write down everything that ring opened before anything is quoted.
Back door, security gate, garage side door, store room, outbuilding, a padlock on a garden gate, a complex pedestrian gate, an office. On the larger stands around Sandhurst, Atholl and River Club that list runs longer than people expect, and the outbuilding is frequently the one holding a ladder.
Doing all of them in one visit shares the callout rather than paying it repeatedly, and it is the natural moment to decide whether they should take a single key. Where different people need different doors, master key systems in Rivonia do that properly instead of with more metal.
What to do in the first hour
If the ring carried anything identifying the address, the order is: phone for a locksmith, then phone whoever administers any electronic access — a managing agent for a complex tag, a security company for a fob, a building manager for an office credential.
Those two calls happen in parallel rather than in sequence, because the electronic side can usually be deactivated within minutes while the mechanical side needs a visit. Doing them the other way round wastes the faster of the two.
Then write the list of every door that ring opened, so nothing is missed on the visit. Front, back, security gate, garage side door, store room, outbuilding, garden gate padlock — the whole ring rather than the obvious door, which is the mistake that produces a second callout a fortnight later.
The version of this that happens at a business
On premises the calculation is different, because the key population is larger and the exposure is not only overnight.
The first question is which doors that key opened, which is answerable in seconds where a register exists and not at all where one does not. Without a register the honest answer is that every door is affected, and that is the expensive version of the same event.
So the response is the same as at a house — change the affected cylinders, count the new keys, write it down — plus one addition: fix the register while it is being rebuilt anyway. That is what a master key system is specified to make possible.

Lost Keys — common questions
Do you keep a record of what was done?
Yes. An itemised invoice describing which doors were attended and what was fitted, along with the key count, which matters for insurance and for the next time the question comes up.
How many keys will I be given?
As many as you ask for, and the number is written down along with who holds each one. That count is the thing that answers this question honestly the next time it comes up.
How soon can the cylinders be changed?
Same day where the keys went missing with something identifying the address, because somebody has a working key and knows where it fits. Where nothing on the ring pointed anywhere, it is booked at your convenience during weekday hours, which costs less.
Should I change every lock in the house?
Every lock that key opened, which is usually fewer than every lock in the house and more than just the front door. Write the list before anything is quoted, including outbuildings, and do them in one visit so the callout is shared.
Can I keep the same keys for all the doors?
Frequently yes, and while the cylinders are open it costs very little. One key opens every external door, which shrinks the ring. The trade-off is that one lost key then affects all of them, which is worth deciding deliberately rather than by default.
My keys were stolen with my address on them. What now?
Treat it as urgent rather than as something to arrange next week. Somebody has a working key and knows where it fits. Every affected door should have its cylinder changed the same day — front, back, security gate, garage side door and any outbuilding on the same ring.
The keys were lost with nothing identifying them. Is it still urgent?
Usually not. A finder has metal and no idea what it opens, so it can be dealt with at your convenience during weekday hours, which costs less. If anything on the ring pointed at your address, the answer changes completely.
Do I need to replace the locks or just the cylinders?
Cylinders in almost every case. The lock is not the problem — the keys still in circulation are — and a new cylinder retires every one of them without touching the handles, the finish or the security gate.
What about the access tag for my complex?
Phone the managing agent or the security company first: tags and fobs can generally be deactivated from their side, which is faster and cheaper than anything a locksmith can do. Older gate remotes sometimes cannot be deactivated individually, which may mean re-coding the receiver.
Can everything be done in one visit?
Yes, and it should be. Doing every affected door in a single visit shares the callout between them rather than paying it three times, and it is also the moment to decide whether you want them all matched to one key.
I have lost my only key. Can you get me in?
In the great majority of cases yes, and without damaging the door where the lock permits. You will need to satisfy the technician of your right to be there before work starts.
What proof do you need for business premises?
A letterhead with matching identification, a lease, or confirmation from the building's managing agent. Mention what you have when you phone so it is sorted before the technician arrives. Anything that genuinely cannot wait is handled as an emergency locksmith call, at any hour.
A master key is missing. How serious is that?
Serious, because it opens well beyond one door and may reach shared areas other tenants rely on. Tell your managing agent immediately, and expect the response to involve changing the cylinder at least the affected branch of the system.
Do I have to change the locks?
Not always. Keys lost anonymously with nothing linking them to the address can be dealt with by changing the cylinders at your convenience. Anything identifying the premises makes it urgent.
