Commercial Security Tips
If your premises has been broken into or your lock is compromised, here's what to do before our locksmith arrives.
Forcing a locked commercial door can cause expensive damage to the frame, lock mechanism or door itself. Our locksmiths attempt non-destructive entry first — often saving hundreds in repair costs.
If your premises has been forced, call the police before touching anything. Once you have a crime reference number, call us for a high-security lock replacement. We'll have your doors secure within the hour.
Many commercial insurance policies require BS3621 mortice locks or 3-star TS007 cylinders. We can tell you on-site whether your existing locks meet the policy spec — and replace them if not.
Avoid “locksmith” ads at the top of Google search results. Many are lead-generation sites that sub-contract to unqualified traders who charge inflated prices without disclosing them upfront. Our prices are fixed and confirmed before we start. Call 020 8050 2017 directly.
Brands We Install
We carry stock of the leading commercial lock brands. If your insurance policy specifies a particular brand or standard, we can supply and fit it.
