When to change a lock — and which one to put in.
The most common reasons people call us for a lock change: moved into a new property, recent break-in or attempted break-in, relationship ended and a key needs cancelling, or the current lock is simply old and failing. All straightforward. The question that matters more is what to replace it with.
Most front doors in the UK have a cylinder lock — either a standard euro cylinder or an older oval profile. If yours is a standard cylinder from before 2015 or so, there’s a fair chance it’s vulnerable to lock snapping, which is how most domestic burglaries are done. A TS007 3-star anti-snap cylinder costs around £89 supplied and fitted and stops that completely.
Insurance is the other consideration. Most home contents policies require a BS3621 5-lever mortice deadlock on the front door for the policy to be valid. A surprising number of homes don’t have one. We’ll check what you’ve got and tell you if your current setup meets your insurer’s requirements — because a lock that doesn’t meet spec means a claim that gets denied.
The job itself usually takes 30-60 minutes depending on the lock type and door condition. We carry most common cylinders and mortice locks as stock, so there’s no waiting for parts on the standard jobs.
