A locked door with your keys inside compresses your judgement into ten stressed minutes. Locksmiths know this; the honest ones work against it, the other kind live off it. A little knowledge levels the field.
Say what kind of lockout it is
There are two very different situations, and the price should reflect which one you have. A slammed door — key inside, lock not engaged — usually opens quickly with non-destructive tools. A locked door with the bolt thrown, a lost key, or a damaged cylinder is more work and may need parts. Say which one it is in the post, add a photo of the lock, and the offers you get will mean something.
Fair pricing has a shape
A serious offer separates the call-out, the opening itself, and any parts if the cylinder must be replaced. Beware of the classic escalation: a low price announced on the phone that triples on the doorstep "because it turned out to be complicated". If the price changes, the explanation should change with it — visibly.
The locksmith should verify you too
A professional who opens a door without asking any proof that you live there is a professional who would open your door for someone else. Expect to show an ID, a document with the address, or a neighbour's confirmation. Treat the question as the good sign it is.
After the door opens
If the key was lost — not just locked inside — replace the cylinder. It is a small part, and it is the difference between an inconvenience and a stranger holding a key to your home. Ask the locksmith to show you the old cylinder and hand over all new keys in the packet.
Where Brikoula fits
Post the lockout with your neighbourhood and a photo of the lock, and locksmiths nearby respond with availability and a price you see before anyone travels. Their reviews from previous customers are attached to every offer. The locksmith spends coins to unlock your contact details — posting costs nothing, even in a hurry.
