A corner shop has one door and a shutter. A large-format retail or distribution building has a customer entrance, a goods receiving area, a yard gate, several personnel doors and a stock area that is effectively a separate building inside the first one. Each of those has its own hardware, its own duty cycle and its own consequences when it fails, and they rarely fail at the same time or for the same reason.
The economics are different too. When a shutter on a small unit fails, a trader loses a morning. When a goods entrance on a distribution premises fails, deliveries stack up, vehicles queue and a scheduling chain backs up behind it. That is why we treat a goods-side failure here with the same urgency as a shopfront elsewhere — the cost is measured in the operation rather than in the door.
Alongside all of it sits ordinary residential Brackenfell: family homes, complexes and newer developments with entirely conventional needs. The two populations have nothing to do with each other except a name, and it is worth saying which one you are when you call, because commercial locksmith stock and domestic stock are not the same vehicle.
