Door slammed shut: the right reflexes before calling a locksmith
The keys are inside and the door has just slammed shut. Before calling anyone, two minutes of checks may save you a call-out — and a few good reflexes will stop you making things worse.

First: the solutions that don't involve a locksmith
Is there a spare key somewhere? Partner, family, friend, trusted neighbour, building caretaker, letting agency, building managing agent (syndic): go through the list. Fetching a spare from the other side of the city is still quicker and cheaper than having the door opened.
Is another way in accessible — without risk? A service door, a ground-floor French window left ajar. On the other hand, never climb a façade and never go in via a balcony: every year, serious falls start with a slammed door.
If you are renting a furnished flat or staying in a managed residence, contact the manager: some keep a master key or a spare at the office.
What not to try
The improvised slip technique with a loyalty card usually ends with a broken card stuck in the door rebate — and sometimes a damaged latch bolt. The technique only works under specific conditions that you cannot judge from outside.
A screwdriver, a crowbar or your shoulder will damage the door and the frame: the repair will cost more than the opening you were trying to avoid. As for a wire coat hanger in the keyway, all it does is push the pins beyond repair.
If the key is still in the lock on the inside and someone is in the home (a child, an elderly person), guide them from outside to turn the key — and if nobody can open the door and there is immediate danger, call the fire brigade (18, the French emergency number), not a locksmith.
How a professional opening works
On the phone, describe the situation: simply slammed shut or deadlocked, type of door, whether there is a seal, which floor. These details determine the method and the equipment.
On site, the locksmith will ask for proof that you live in the property — that is normal, and in fact a sign of a serious professional. If your papers are inside, say so when you call: other forms of proof may be accepted.
A door that has slammed shut without being deadlocked can most often be opened with a non-destructive method, with no damage and no parts replaced. The quote presented before the work should reflect that reality: for a standard slammed door, be wary of a quote that assumes drilling and a new cylinder from the outset.
