Changing your locks is one of the most effective ways to enhance your property's security. Whether you have moved home, lost your keys, or simply want to upgrade outdated hardware, a professional lock change ensures the work is completed correctly, safely, and to a standard that meets insurance and police recommendations.
Why Professional Installation Matters
Installing a lock may appear straightforward, but improper fitting creates security vulnerabilities. A mortice lock installed without proper keep alignment, a euro cylinder protruding beyond the handle, or incorrect screw lengths can all undermine the lock's effectiveness. Professional locksmiths understand the precise tolerances and techniques that ensure maximum security.
British Standard Compliance
Many home insurance policies require locks meeting British Standard BS3621. A professional locksmith identifies your current locks' compliance status and recommends appropriate upgrades. Installing non-compliant locks may invalidate your insurance or reduce claims payments after a burglary.

- Moving into a new property — you cannot know who has copies of existing keys
- Lost or stolen keys — treat as a potential security breach
- Tenant changeover — landlords must protect current and future occupants
- After a break-in — even if the lock held, internal damage may compromise future security
