  6. A free survey beats a guess

Search for business security and you'll drown in cameras — and cameras matter, but they mostly record losses rather than prevent them. Underneath the technology sits an older layer that decides whether anyone gets in at all: doors, locks and, above everything, keys. That layer is our trade, and it's where most small-business security quietly fails. Here are the essentials.

Key control: the question that catches owners out

Ask yourself, right now: exactly how many keys to your premises exist, and who holds each one? Most owners can't answer — and the classic failure follows from it: the ex-employee, the old cleaner or the previous contractor whose key still works months after they left. Start a simple key log (key number, holder, date issued, date returned), make return-on-departure a standing policy, and change the relevant locks whenever a key can't be accounted for.

Restricted keys: copies only on your say-so

Standard keys can be copied at any kiosk in minutes, which makes a key log half a measure. Restricted (patented) key systems close the loop: the blanks are legally protected and copies are only cut against an authorised signature, so "I'll just get one cut at lunch" stops being possible. For any business with staff keys in circulation, it's one of the highest-value upgrades available.

Master key systems, demystified

A master key system gives you one key that opens everything while each member of staff carries a key that opens only what their job requires — the stockroom but not the office, the front door but not the safe room. Beyond convenience, the real benefit is containment: a lost staff key compromises one area instead of the whole building, and the re-securing bill shrinks to match.

Commercial doors: security and escape, both

Business premises carry a constraint homes don't: people must always be able to get out. Fire-exit and panic hardware has to let occupants leave instantly without keys, while still resisting entry from outside — a balance that's easy to get wrong in both directions, and one insurers and fire risk assessments both care about. Commercial insurance wording also tends to specify lock standards on final-exit doors; it's worth knowing yours before a claim tests it.

If the worst happens

After a commercial break-in, speed is continuity: same-day boarding and securing, proper repairs, and — critically — upgrading the exact path they used, because burglars return to premises that worked the first time. Trading resumes fastest when the securing and the upgrade happen in the same visit.
