When Should You Change Your Locks? 7 Times It Pays (and What It Costs)
It's about events, not calendars. Moving house, lost keys, a break-in, an ex with a key, a lock that's started telling you — the seven moments the trade takes seriously.

"Lightning doesn't strike twice" is a comforting idea, and for burglary it is simply false. Our locksmiths occasionally find themselves standing at a door they've repaired before, and the research backs up what that feels like: being burgled once measurably raises the odds of being burgled again, often soon. The good news is that the reasons are practical rather than mysterious — which means they can be removed.
Studies of repeat victimisation point the same way: a substantial share of burglary victims are hit more than once, the highest-risk window is the first weeks after the original break-in, and a small fraction of properties absorbs a wildly outsized share of all burglaries. One UK survey found around one in six victims had been targeted three or more times — most at the same property. A first burglary is not just a loss; statistically, it is information.
Think about what the first visit taught them. They know the layout, the exits, and how long they had. They know exactly which weakness let them in — and whether it's been fixed. They know what they left behind, and that insurance will soon replace what they took with newer versions of the same things. Some pass the details on. From the burglar's side of the ledger, a previously successful house is the lowest-risk job available.
Once the police have done their part, the priority is making the property genuinely secure rather than apparently secure. That means repairing the entry point properly — not a sheet of board and good intentions — and changing the locks if there is any chance keys were taken, copied or even seen; our guide on when to change your locks covers the judgement call. Photograph and list everything for the insurer while it's fresh. This is precisely the work of a burglary-repair call-out, and it's a same-day job for our locksmiths.
The entry method is the lesson the burglary taught you, so spend your money on that exact path. A snapped cylinder calls for a rated anti-snap upgrade on every similar door, not just the broken one. A levered frame calls for reinforced keeps and hinge bolts. A reached-through letterbox calls for key discipline and a cage. Repairing like-for-like restores yesterday's weakness; upgrading retires it.
The post-burglary period rewards ordinary vigilance: unexpected callers who melt away when answered, repeated knocks with nobody there, gates or bins subtly moved. Tell the neighbours what happened — streets where people talk are streets burglars avoid, and your experience upgrades everyone's attention for free.
A named, vetted master locksmith covers your area — no call-out fee.
You can't un-burgle a house, but you can make the return trip a waste of their evening: the old way in upgraded beyond their tools, new habits at the door, lighting where there was cover, and neighbours paying attention. If you've been burgled recently, our locksmiths handle the whole sequence — emergency securing, proper repairs, and the upgrades that close the path for good — with fixed prices and no call-out fee.
