Standard euro cylinder locks remain one of the most common weak points in home and business security. Knight & Falcon Locksmith supplies and fits British Standard high security locks across London, designed to resist the most common forced entry methods.
Lock snapping is a technique that allows an intruder to break through a standard euro cylinder in seconds using basic tools, without needing to pick or drill the lock at all. Many London properties fitted with original uPVC or composite doors remain vulnerable to this method.
High security locks typically meet British Standard BS3621, combining anti snap, anti pick, anti drill, and anti bump features engineered directly into the cylinder, significantly increasing the time and difficulty involved in a forced entry attempt.
Many home and business insurance policies specify a minimum lock standard as a condition of cover. Upgrading to British Standard hardware helps bring your property in line with typical insurer requirements, though exact wording should always be confirmed with your provider.
All high security locks are fitted by DBS checked, fully insured technicians, with every installation backed by a 12 month warranty on parts and workmanship.
