If your key has snapped off inside the lock, the first thing to do is stop turning or pulling at what's left of it—you'll only push the broken part deeper or damage the lock mechanism further. The safest approach is to call a locksmith who can extract it properly using specialised tools. If you want to attempt removal yourself, you can try using a thin piece of metal (like a paperclip or small saw blade) to hook and gently pull the broken piece out, working at the same angle the key entered. Wiggle slowly and carefully; forcing it will make things worse. If you can't dislodge it within a minute or two, stop and get professional help rather than risk turning a removable broken key into a permanently locked door.
A broken key usually happens one of two ways: the key simply snaps under pressure (often because it's old, worn, or the lock has seized), or it's already been slightly damaged and finally gives when you turn it. You'll either feel it snap or notice the part in your hand came off too easily. The part still in the lock is now blocking access until it's removed.
Don't ignore signs that your lock or key is getting close to breaking. If a key turns stiffly, requires excessive force, or feels like it's about to crack when you use it, that's a warning. A worn or bent key that doesn't slide in smoothly will put uneven pressure on the lock internals and is much more likely to snap. If you've already had one key fail in a particular lock, the lock itself may be the problem—not just the key.
A DIY extraction is worth attempting only if you can see the broken piece clearly, it's sitting near the front of the lock, and you have a thin, sturdy tool that can reach it without damaging the lock housing. A small hook, thin saw blade, or even a straightened paperclip can work if you're patient. The key is patience: work in very small movements, turning the hook or tool gently to catch the broken piece, then ease it out rather than yank it.
Stop immediately if the broken piece won't budge within a couple of minutes, if it's deeply embedded, or if you feel any resistance that suggests you're grinding it against the internal pins. Trying to force a stuck piece will bend it further and can damage the lock pins inside, turning a simple extraction into a full lock replacement. The same goes if you can't see the piece at all—it's already deep enough that you need professional tools.
In Finchdean, a lot of properties have older locks, and older locks are often tighter and less forgiving. Forcing a removal on a vintage or heritage lock is a genuine risk.
A locksmith has extraction tools specifically designed for this: hooks, picks, and sometimes even tiny forceps that can reach broken pieces without damaging the lock. They'll also be able to tell you whether the lock itself is still safe to use or whether the piece being stuck has already bent the internal pins beyond function.
More importantly, a professional can work fast without the trial-and-error that usually comes with a first attempt at home. They'll also assess the lock after removal—sometimes a key breaks because the lock is failing, and you'll want to know that before you get locked out again.

If it's a door lock you use every day, a broken key inside it isn't just inconvenient—it's a security issue until it's fixed. You need to know the lock is working properly and that no one else can see or access the internal mechanism while the piece is still lodged in there.
Once your key is out, don't just carry on with the same key if it shows any wear. Get a spare cut while the original still works properly—worn keys are far more likely to snap. If the lock itself was the culprit (stiff, difficult to turn, or the key was only moderately forced), have it serviced or replaced. A working lock should turn smoothly; if yours doesn't, the internal mechanism is degrading.
For practical advice on keeping your locks healthy and avoiding these situations, this guide explains how to maintain and use your locks safely. It's less costly to replace a key or service a lock than to deal with emergency lockouts and broken keys repeatedly.
A good locksmith will arrive with the right tools and usually extract a broken key in under ten minutes. They'll inspect the lock to confirm it's still working safely, discuss whether you need a replacement key cut, and advise on the lock's condition. They won't charge you extra for the inspection after removal—that's part of the job. Local businesses in the area know that a reliable locksmith is someone you call when you actually need help, not someone who overcomplicates a simple job to inflate the bill.
