Let me answer the real question first: a plain slammed door is something we open in Frankfurt almost always without any damage, and during the day a fair price sits between 80 and 150 euros. Nights, weekends and public holidays cost more. But even at night a simple door opening should not run past 200 to 250 euros. Anything above that is either a genuine lock problem or a rip-off.
I have been doing this for 22 years. In that time I have opened more slammed doors than I can count, from the old-build flats in Nordend to the new blocks in Niederrad. And the most important sentence I can give you sits right at the start: stay calm. A slammed door is the most harmless of all lockouts.
Slammed shut is not the same as locked
This is the part that decides everything. Price, time, whether anyone has to drill. If you only pulled the door shut and the bolt was not turned twice, the door is held by the latch alone. That little angled tongue that snaps in when the door closes. A trained technician pushes it back in a couple of minutes. No drilling. No new lock. No drama.
If the bolt was actually turned, meaning the key went round once or twice, it is a different story. Now the deadbolt is engaged, that thick rod that drives deep into the frame. Depending on the cylinder it takes much longer, and in some cases the lock has to be replaced.
So my first piece of advice for the call: say exactly what the situation is.
- Is the key still inside the lock?
- Is it lying on the hallway table indoors?
- Did you lock it, or only pull the door shut?
- Is it a normal flat door or a security door with multi-point locking?
These four answers decide both time and price. An honest firm asks all of this without being prompted. If it does not, it wants to surprise you on site.
Before you call anyone
Breathe first. Sounds trivial. But the most expensive mistakes happen in a panic, I see it every week. Calmly go through this list before you even pick up a phone.
- Is a window or the balcony door tilted open? Sometimes that is the faster and free route, especially on the ground floor.
- Does a neighbour hold a spare? In a lot of apartment blocks in Bornheim or Nordend the caretaker or the management keeps one.
- Is there a key safe on the building, for example with lettings run by a property manager?
- Is a child or a pet alone inside, or is the stove on? Then it is a genuine emergency. Say so straight away, both to us and, if in doubt, to 112.
What you must never do: pry at it yourself with a card, wire or screwdriver. Every week I see a scratched frame or a worn latch that jams afterwards. The bank-card trick from the internet usually only ruins the card and the door. The repair then costs more than the opening would have. Hands off.
And if the door is a security door?
Then even a plain slammed situation gets more involved. Modern flat doors to DIN EN 1627 in resistance class RC2 or RC3 often have multi-point locking that throws several bolts the moment you pull the door shut. This needs experience and patience, not a drill. Anyone who reaches for the drill straight away on a door like that either has no idea or wants to sell you a new cylinder. Both are bad.
What a door opening in Frankfurt really costs
Here is plain talk, no sugar-coating. These are realistic spans, the way I bill them myself and the way they are fair in the trade.
| Situation | Fair price |
|---|---|
| Slammed, daytime (Mon to Fri, 8 am to 6 pm) | 80 to 150 euros |
| Slammed, evening or weekend | 120 to 200 euros |
| Slammed, night or public holiday | 150 to 250 euros |
| Locked, standard cylinder | from about 150 euros plus parts |
| Cylinder swap, standard (parts) | 15 to 40 euros |
| Cylinder swap, security such as ABUS or BKS (parts) | 60 to 150 euros |
These numbers are not fixed prices set in stone, they are spans. The trip, the time of day and the door type shift them. But if someone wants 400 euros for a slammed door in the middle of the day, something is wrong. You will find a full overview on our pricing page, and more on the night surcharges in the guide on night, weekend and holiday rates.

How to recognise a fair locksmith
A serious firm gives you a price range on the phone before driving out. Not a fixed quote for everything, that would be dishonest, because nobody sees the door through the phone. But an honest span. If someone dodges every number and just says we will see on site, hang up.
I also get suspicious of free 0800 numbers that route you to a call centre somewhere in Germany. It sits in Hamburg or heaven knows where and sends whichever subcontractor bills the most that night. That has nothing to do with a local Frankfurt locksmith. More on this, with all the typical tricks, is in our piece on overpriced locksmiths.
The red flags at a glance:
- No price information on the phone, only excuses.
- Cash only, no invoice, no card reader.
- Drilling on a door that is obviously only slammed.
- Sudden add-ons on site, for example for supposedly necessary special tools.
- An 0800 number with no Frankfurt address in the legal notice.
A reliable source that backs this up is the Verbraucherzentrale, the consumer advice centre. They have been warning about exactly these call-centre tricks for years. If you are unsure, take a quick look there before you order anyone. You will find the link at verbraucherzentrale.de.
Last week in Sachsenhausen
Last week a customer stood outside her flat in Sachsenhausen at 10 pm, the groceries still in the stairwell, the ice cream already melting. Door slammed, not locked. A classic. We were there in 20 minutes, the door open in three, 140 euros including the night surcharge. She got a proper invoice, I drove off again. That is exactly how it should go. No drilling, no theatre, no surcharge out of nowhere.
And a counter-example from Gallus
A few weeks earlier a man from Gallus called me, pretty upset. Another service, ordered through an 0800 number, had drilled out the cylinder of a plainly slammed flat door and demanded 480 euros at the end, cash, no proper invoice. The door had not even been locked. They destroyed something completely unnecessarily just to sell expensive parts. I fitted him a new, proper cylinder and advised him to dispute the bill. You do not have to accept that kind of thing.
When the lock really is the problem
Sometimes the door was already damaged before it slammed, or the cylinder simply gives up. Old cylinders, especially cheap models with no norm, jam eventually. If the key only turns with force or spins freely in the lock, that is a warning sign.
Then we are talking about a replacement. Look for a cylinder with a sensible security grade to DIN EN 1303, ideally with anti-drill and anti-pull protection. Brands like ABUS, BKS, Winkhaus or EVVA are solid. On fitting, the rule is: the cylinder must not stick out on the outside, otherwise it can be levered off. What the replacement costs and when it makes sense is in our guide on lock replacement.
If you are thinking beyond a plain door opening towards burglary protection, after a lockout or because the whole building has old hardware, then it is worth a look at our burglary protection services. And in an acute case, in the middle of the night, our emergency service is there around the clock across all of Frankfurt.
A short FAQ on the slammed door
Does a slammed door have to be drilled? No, almost never. A merely slammed door is held only by the latch, and that can be pushed back without damage. Anyone who drills straight away here is doing something wrong.
How fast does someone arrive? In Frankfurt, depending on the district, we are usually on site in 20 to 40 minutes, faster in the city centre, Westend or Bockenheim, a bit longer on the edge of town.
Does insurance pay for the door opening? For a plain slammed door, usually not, that is not an insurance case. It can look different after a burglary or a lost key. Always keep the invoice.
What does it really cost at night? A simple opening should not exceed 150 to 250 euros even at night. If someone wants more, ask for the reason or call someone else.
Bottom line: a slammed door is the most harmless of all lockouts. Stay calm, check windows and neighbours first, ask for the price on the phone, and let nobody drill who does not have to. If you are unsure, just call us, we will tell you honestly what the situation is. You will find us through our contact page.
