Residential Locksmith in Dulwich & South London
Your home security is only as strong as the weakest lock on the weakest door — and in Dulwich's housing stock, that weak point is predictable. Victorian and Edwardian terraces with original timber doors often still carry standard euro cylinders with no anti-snap protection. Converted flats mix door types across floors. New-builds rely on UPVC multipoint mechanisms that wear with age. We've worked through all of it since 2014.
A residential visit from us starts with honest advice, not a sales pitch. We'll tell you which locks genuinely need upgrading to satisfy your insurer — typically a TS007-rated anti-snap cylinder or a BS3621 mortice deadlock — and which are fine as they are. Every job gets a fixed price before we start and an itemised invoice afterwards.

Residential Locksmith — FAQs
Should I change the locks when I move house in Dulwich?
Yes — it's the first thing we recommend. You have no way of knowing how many copies of the existing keys are in circulation with previous owners, tenants, cleaners or tradespeople. We can rekey every external cylinder on moving day from £55 per cylinder, with all locks tested before we leave.
What locks do I need to satisfy my home insurer?
Most UK insurers require either a BS3621-rated mortice deadlock on timber doors or a TS007-rated (1-star cylinder plus 2-star handle, or 3-star cylinder) setup on UPVC/composite doors. We supply and fit insurance-approved locks and provide documentation your insurer will accept.
How much does it cost to upgrade to anti-snap locks?
Anti-snap cylinder replacement starts from £55 per cylinder supplied and fitted. A typical Dulwich terrace with a front and back door usually needs two cylinders, and we complete both in a single visit.
