What does it mean when a lock is up to BS3621 standards?

Commercial properties are usually subjected to heavy wear and tear due to every day use and so usually require grade 1 locks – the strongest available. In Brighton, commercial locksmiths will also be able to install and repair a variety of security systems specifically designed for commercial use; panic bars, master key systems, safes and filing cabinets. Locksmiths will usually recommend a grade 2 lock for homes with slightly heavier daily traffic and light commercial use, with grade 3 used for most residences.
