It's the question everyone asks while they wait on the step: are you going to wreck my door? Almost always, the answer is no. A trained locksmith's whole craft is getting you back in without harming your lock or your door — and, just as importantly, knowing that trying it yourself is usually what causes the very damage you're dreading.
Non-destructive first, always
A good locksmith's default is to open a door without damaging anything, so that when the job's done you keep your existing lock and your existing keys, exactly as they were. Reaching straight for a drill is the mark of someone who can't do it any other way. On the vast majority of house lockouts, the door is opened, tested, and handed back working perfectly.
How that's done, in plain terms
Without turning this into a manual — we don't publish methods, and no responsible locksmith should — non-destructive entry comes down to skill and the right tools rather than force. A locksmith reads the lock, then works with its mechanism to release it cleanly; on modern electronic and smart locks, that may instead mean an authorised override or reprogramming. Whatever the route, the lock is checked afterwards to make sure it still works exactly as it did before.
Why a good lock can take a little longer
Here's the irony worth knowing: the better your lock, the longer a clean open can take. Anti-snap and other high-security cylinders are specifically designed to resist exactly these techniques — that's the whole point of them. So if your locksmith takes their time on a quality lock, that's the lock doing its job, not a locksmith struggling. Our guide to anti-snap locks explains why that resistance is worth having.
When drilling is genuinely the last resort
Occasionally — a seized, already-damaged, or very high-security lock — a non-destructive open isn't realistic, and the cylinder has to be drilled. A straight locksmith will tell you that before they start, explain why, and fit a replacement on the spot. The key point: after a proper non-destructive open you do not normally need a new lock at all.
Why DIY usually makes it worse
Credit cards, screwdrivers, hairpins and online videos are how clean lockouts become expensive ones. Untrained force damages the lock, the latch and often the frame, turning a job that would have left no trace into a lock-and-repair bill. There's a second reason to call a professional, too: a locksmith will first make sure you're entitled to enter — our guide on how locksmiths check you own the property explains that step.
Locked out? Here's what to expect
Stay calm and somewhere safe with your phone. Your local locksmith will confirm you're entitled to enter, open the door using non-destructive methods, and test the lock before they leave — a named, vetted professional, with no call-out fee. Our guide on being locked out of the house covers the rest, and you can find your local LocksmithLocal through our locked-out service.
