Lock Changes in Canterbury

Listed properties in the city centre conservation area usually require period-appropriate hardware, so we fit BS3621 mortice deadlocks in finishes and case styles that match the original joinery rather than modern stock units. Planning and conservation officers generally accept this standard providing the visible furniture, such as escutcheons and handles, respects the building's age. We can advise on suitable options once we have seen the door and its listing grade.

Many interwar semis in Hersden still have euro cylinders fitted before the anti-snap requirements became standard practice, leaving them vulnerable to snapping attacks. We recommend upgrading to a TS007 3-star rated euro cylinder, which combines anti-snap, anti-drill and anti-pick features and satisfies most insurance policies. This is a straightforward cylinder swap rather than a full door mechanism replacement, so the work is contained and the cost reflects the hardware rather than extensive labour.

For multi-occupancy properties with regular tenant changes, we generally recommend a keyed-alike or master key system with key control, so that individual locks can be rekeyed between lets without recutting every key in the building. Pairing a BS3621 mortice deadlock on final exit doors with a night latch for day-to-day use gives tenants an easy self-closing option while keeping the main deadlock for security when the property is empty. Restricted key control also limits unauthorised key copying, which is a common concern in shared student housing.
