I have driven the night shift in Frankfurt for eight years and every week I see the trail these people leave. Plainly: you unmask most scammers on the phone, before anyone drives out. If no price is named on the call, hang up. Full stop. That is the one rule that protects you from almost everything.
Everything else in this text is just fine detail around that one rule. But the fine detail is worth it, because the trade has gotten inventive.
Why locksmith work gets scammed so often
There is a simple reason. You are standing outside your door at night, cold, wanting your bed. In that state nobody compares three quotes. The scammers know exactly that. They are not selling you a service, they are selling you the end of a stressful moment. And for that people pay almost any price.
On top of that: a slammed door opens in two minutes. The effort is laughably small, the felt value huge. That gap between real effort and felt value is the whole business model of the fraudsters. A serious firm does not exploit it. A dodgy one lives off it.
The scam starts on Google
Many of these providers are not Frankfurt firms at all. They run ads with an 0800 number and an address that does not exist. You call, you land in a call centre somewhere in Germany, and it sends whoever bills the most brazenly and hands over a cut of the loot.
Watch the address. Type it into the map. If there is a hairdresser, a kiosk or a patch of grass there, you know enough. Real locksmiths in Frankfurt have a workshop, a listing, often the same number with the 069 area code for years. How to spot such fake firms already in the search results is set out in detail in our piece on fake firms on Google.
The seven warning signs on the phone
This is your most important tool. It costs nothing, it takes two minutes, and it filters out most fraudsters before they even have your address.
- No price quoted. "We will see on site" is the standard excuse.
- A free 0800 or 0180 number with no real local area code.
- No company name, no address, just a mobile number on the website.
- Pressure on the phone: "We only have one van free right now."
- Cash only, no invoice, no card.
- A quoted range that is suspiciously low, 29 euros call-out, the rest comes later.
- The agent dodges when you ask about the actual trade business behind it.
A real firm names a price range, a name and an address. That simple is the first filter. Do not be dazzled by a slick logo that a fake but serious-looking website copies together in two hours. What counts is the question about the price, and whether someone answers it straight.
A small trick of mine: ask concretely. "What does a slammed door cost, daytime, no damage, cash or card?" Whoever gives you a clear number is usually fine. Whoever waffles, not.
What it may cost, and what it may not
So that you know on the phone and at the door whether the number is realistic, here is my honest range for Frankfurt 2026.
| Situation | Fair price |
|---|---|
| Slammed door, daytime, no damage | 80 to 150 euros |
| Slammed door, night, weekend, holiday | 150 to 250 euros |
| Deadbolted door, depending on lock and effort | more, clarify beforehand |
| Cylinder swap, standard cylinder | 15 to 40 euros part plus labour |
| Security cylinder, good, ABUS, BKS, Winkhaus | 60 to 150 euros plus labour |
If someone wants 500 or 600 euros for a slammed door at night, that is not a service, that is a rip-off. The full breakdown with every line item is in our guide on the 2026 price list. Read the five minutes before you need them. In an emergency you have no time for it.
Locked out and in a hurry?

What happens on site
Last week, half past midnight, I arrived after a man from another company in Bockenheim. He had drilled open a slammed door, not even deadbolted, and wanted 580 euros cash. Nobody who knows the trade drills a slammed door. That is the clearest sign there is. You push the latch back in minutes, with zero damage, just like with any clean door opening.
Another case that stays with me. In Nordend, an older lady, alone, middle of the night. A provider had quoted her 49 euros on the phone. At the door it became 690 euros, supposedly because of "special tools" and a "security lock". It was a perfectly ordinary slammed lever-lock fitting. She had already signed and paid in cash by the time I came for a neighbour the next day and heard the story. The money was gone. That is exactly why I am writing this text.
If on site they suddenly demand many times what was quoted on the phone, sign nothing and do not pay the full fantasy figure. Insist on an invoice with a company name and address. Note the vehicle number plate.
These door-step tricks you should know
- The drill comes out first, even though the door is only slammed. Create damage, then "repair" it expensively.
- Sudden extra line items: call-out, night surcharge, material, all separate and overpriced.
- A new cylinder is talked into you, even though the old one is perfectly fine.
- The card reader "unfortunately is not working right now", cash only.
- The invoice will come "later by post" and never comes.
How to fight back, step by step
Stay calm. That is half the battle. The fraudster needs your panic.
- Pay, under protest, at most the amount that was quoted beforehand on the phone, and get it receipted.
- Say loud and clear that you consider the rest excessive and are not paying it voluntarily.
- Sign nothing you do not understand. A signature extorted in distress does not simply bind you.
- Note the name, number plate, time and take photos of the door and the invoice.
- Report the case to the consumer advice centre and, where there is clear coercion, to the police.
If you have already paid too much, not all is lost. With cash it gets hard, with card or bank transfer you have something to work with. An excessive demand made under pressure can be unconscionable. Get advice before you give up.
How a serious emergency service works
The fair alternative is unspectacular. That is precisely the point. A price range on the phone. A receipt on site. No drilling without reason. A card reader that works.
With me it goes like this: you call, I give you a range, I name myself and my business. I come, I look at the door, and if it is a slammed one, I open it without a drill. You get an invoice. Done. If a lock really is broken and has to be swapped, I explain beforehand what a lock replacement costs before I start.
And if you live in Sachsenhausen, in Gallus or in Bornheim and you are standing outside your door at night, then call a fixed local business directly rather than tapping the first Google ad. Our emergency service works exactly by these rules. Stay calm, ask the price, and when in doubt hang up.
Quick questions, quick answers
Do I have to pay if the price on site is much higher than on the phone? The price quoted on the phone yes. The excessive surcharge not simply so. Pay under protest and get it receipted.
Is a slammed door allowed to be drilled open? No, not without reason. A merely slammed door is opened by any professional without damage. The drill here is a warning sign, not a tool.
How do I spot a serious provider fastest? By a clear price quote on the phone and a real Frankfurt address with a 069 area code. Both together filter out most fraudsters.
What if I have already paid in cash? Difficult, but not hopeless. Gather evidence, report it to the consumer advice centre and consider filing a complaint. Next time, ask the price beforehand.
