In a single week here we might rekey a shared student house, open a flat in a new development, replace a workshop roller-shutter lock on Sir Lowry Road and sort out a family home that has been in the same hands for decades. Very few Cape Town suburbs ask a locksmith to switch between those registers, and it is the reason Zonnebloem is worked by a unit that carries both domestic and commercial stock.
The student and shared-housing layer generates the highest volume. Houses let by the room mean four or five people holding keys to one front door, a turnover every academic year, and a steady stream of situations where nobody can say how many keys exist. That is straightforward lock change work, but it needs doing on a schedule rather than after something has gone wrong.
The commercial layer along the lower edge is the opposite: fewer calls, higher stakes. A workshop, printer or small manufacturer with one roller shutter and one steel door cannot trade at all if either fails, which is why a business lockout here is treated with the same urgency as somebody standing outside their home at midnight.
