Locked out: how to get back in without damage

Door shut and keys inside? The differences that matter (latch vs deadbolt), what to try, and how much a locksmith’s opening costs.

It happens to everyone, usually at the worst possible moment. The first thing to work out is HOW the door is locked: it changes everything, from the opening method to the price.

What to do, in order

1
Work out how the door is locked

Latch only (you pulled the door shut and the keys are inside): opening is almost always possible without any damage. Locked with the deadbolt thrown, or with the key left in on the inside: it needs work on the cylinder, which is longer and more expensive, but a good locksmith limits the damage to the cylinder alone (€30-80) and not the door.

2
Check alternative ways in (safely)

An accessible balcony French door, the service door, keys left with a neighbour or a relative. Don’t climb: no lock is worth an accident.

3
Call a reliable locksmith — and ask the price first

Describe the type of door (armoured or standard) and how it’s locked: a serious professional will give you a price range over the phone and confirm it before starting. Be wary of anyone who won’t commit or who promises ridiculous figures ("from €29") that then multiply on the spot.

What NOT to do

  • No credit cards on the door: it only works in films, and it ruins both the door and the card
  • Don’t try to force the tilt window: it’s the most common way to get hurt
  • Don’t accept a call-out without an indicative price agreed beforehand — it’s the most documented scam in the trade
  • Don’t let them drill the cylinder as a first option: non-destructive opening should be tried first

When you need a technician

Always, if you don’t have a safe alternative way in. With a latched door the locksmith opens in a few minutes without damage; with the deadbolt thrown they replace the cylinder while leaving the door intact. If they tell you they need to "break everything", ask for a second opinion.

Frequently asked questions

How much does it cost to open a latched door?

Roughly €80-150 during weekday daytime hours; nights and holidays carry a 30-50% surcharge. The price should always be agreed before the work.

Can the locksmith ask me for ID?

Yes, and it’s a good sign: a serious professional checks that you’re entitled to enter (ID with the address, or a neighbour’s confirmation). Be wary of anyone who opens without asking anything.
