I'm worried about damage — do you actually pick locks open, or is drilling the usual method?

Picking is genuinely the method we prefer and the one we try first on standard cylinders and mortice locks. A skilled locksmith can defeat most mechanisms by feel alone, so the lock keeps working and there is nothing to replace afterwards. Wherever we are called out in Harpenden the engineer will study the door first and choose the gentlest route that gets you safely back inside.

The window and door were smashed during the raid — can you board things up so the house isn't left open overnight?

Absolutely. If a door or window has been smashed and can't be made secure straight away, we board it up solidly so your property in Harpenden isn't left open to the weather or to anyone else. It's a proper temporary fix that holds firm until a permanent repair or glazing can be arranged, and it means you can lock up and rest tonight.

What's the actual difference between rekeying a lock and fitting a brand new one?

Rekeying alters the internal pins of your existing lock so the old keys no longer fit and you get a fresh set, all while the lock body itself stays on the door. Replacing means removing the whole unit and installing a new one from scratch. When our locksmith reaches you in Harpenden, they'll open up the mechanism, check its condition, and tell you honestly which route makes sense for your situation.

What details should I have ready before I ring you out to Harpenden?

The most useful things to give us are where you are in Harpenden, a quick description of what's gone wrong, and a rough idea of the door or lock involved. Something as simple as a uPVC front door that won't lock, or a night latch you've been shut out of, helps us load the right tools before we leave. If you're unsure about any of it, don't worry — we'll talk it through with you on the phone.

I'm worried the trapped fragment has knocked the mechanism about. Once the broken piece is out, will you be able to check whether the lock still turns properly?

Once the broken piece is out we always test the lock thoroughly before leaving, turning it several times to be sure nothing inside has been knocked out of true. If the fragment has worn or bent the mechanism we'll tell you plainly and sort a repair or replacement, so you're not left with a lock that fails again a few days later.

If a key goes missing or someone in the house loses theirs, how do I stop that turning into a lockout?

The moment a key can't be found, treat it as a prompt to act rather than something to worry about later: fall back on the household's known spare, and if the key might be genuinely lost rather than misplaced, think about changing or rekeying the lock so a stranger can't use it. It helps enormously if everyone knows in advance where the spare lives and who holds one, so a missing set never leaves the whole house shut out. Should you end up stuck on the doorstep regardless, one call to us and we'll walk you through what to do next.
