Secure every external door with tested cylinders, keep mechanisms and closers in good order, control who holds keys, and check what your insurer specifies. Commercial premises live or die on the boring fundamentals: solid locks, controlled keys, and no neglected back door.
Securing business premises is not complicated, but it is easy to leave gaps when you are busy running the place. This is the checklist a locksmith would work through on a commercial security visit.
1. Every external door, properly locked
Front, back, side, fire exits and yard doors. Fire doors must still allow escape from inside, but should resist entry from outside. The back and yard doors are where many commercial break-ins happen, precisely because owners focus on the shopfront.
2. Tested, correctly sized cylinders
The same snapping vulnerability that affects homes affects commercial uPVC and aluminium doors. Fit tested anti-snap cylinders, sized so nothing protrudes. On glass and aluminium shopfronts, make sure the hook bolts and mortice locks are sound.
3. Door closers and mechanisms in good order
A door that does not close and latch properly is not secure, however good the lock. Check closers, hinges and multipoint mechanisms, and repair anything dragging or misaligned before it fails.
4. Key control
This is where businesses leak security. Know who holds keys, use cylinders that cannot be copied casually, and recover or re-cylinder when staff leave. For anything beyond a couple of doors, a master key system turns key control from guesswork into a plan.
5. Shutters, grilles and vulnerable glazing
Where appropriate, roller shutters or grilles protect glass frontages out of hours. Make sure their locks are as strong as the rest, a shutter with a weak padlock is only as good as that padlock.
6. What your insurer specifies
Check your policy. Many commercial policies specify a minimum lock standard, often a British Standard mortice or a particular cylinder grade, and a claim can be challenged if the locks fitted do not meet it. It is far cheaper to confirm and comply now than to discover the gap after a break-in.
Insurers reward the basics. Meeting the lock standard in your policy is one of the easiest things to get right and one of the most expensive to get wrong.
Bringing it together
None of this is exotic. It is solid doors, tested locks, controlled keys and no neglected entrance. A locksmith can walk the premises with you and turn this checklist into a short, costed list of what actually needs doing. See our commercial locksmith service.

Frequently asked questions
What lock standard do business insurers usually require?+
It varies by policy, but many specify a British Standard mortice lock or a particular cylinder grade on final exit doors. Always check your own policy wording, as fitting locks below the specified standard can affect a claim.
Are commercial doors vulnerable to lock snapping too?+
Yes. uPVC and aluminium commercial doors use the same euro cylinders as homes and are just as exposed to snapping if a standard cylinder is fitted. Tested anti-snap cylinders are the fix.
Do you secure premises out of hours to avoid disruption?+
We work around businesses wherever possible, including quieter periods, so security upgrades and repairs cause the least disruption to trading.
