Most people do not lose their money on the lock. They lose it on the number they dial first. I have answered emergency calls for seven years, and the pattern is always the same. Anyone who panics, taps the top Google ad, and finds an 0180 or 0800 number with no real address has almost always landed in a dispatch centre, not at the tradesperson around the corner. And that is what makes the evening expensive.
Let me show you how to spot the trap on the phone before anyone sets off. The first three sentences on the line often already decide whether you pay 120 euros or 480 euros.
What a dispatch centre actually is
A dispatch centre is not a locksmith. It is a call centre. Often it is not even in Frankfurt, sometimes not even in Hesse. These centres buy ads and top spots on Google, take your job, and then sell it on to whichever firm pays the highest commission.
For you that means: the person you talk to never comes to you. They type your address into a system, and somewhere a subcontractor you never chose sets off. Longer drive. Higher prices. No face you can find again if the invoice is wrong.
And the commission the call centre pockets, who pays that in the end? You do. It is baked into the price, always.
Why the number itself is already a warning sign
An 0800 number is free for the caller, that is true. But it also tells you that behind it sits a nationwide dispatch system, not a local firm. No Frankfurt tradesperson I know runs an 0800 hotline. Why would they.
An 0180 number is even worse. That one can cost you by the minute while you sit on hold listening to music. Depending on the tariff that quickly adds up to several euros before anyone even picks up.
A real firm from Frankfurt has a perfectly normal landline with the 069 area code. Or a reachable mobile, where a person answers who knows where Bornheim is and how long it takes to get from there to Sachsenhausen.
The lines where I hear the trap straight away
Over seven years on the phone I have developed a feel for it. When a caller repeats to me what the other number said, I often already know what happened. These lines are the red flags:
- "We can only tell you the price on site." This is the most common one. A serious firm gives a range. By day, 80 to 150 euros for a slammed door, done. Anyone who dodges every figure wants to surprise you afterwards.
- "We happen to have a technician near you right now." Sounds reassuring. But it usually means: we hand the job to whoever wants the commission.
- "Cash only, no invoice." Hang up immediately. A tradesperson who writes no invoice does not want to be found.
- "The door has to be drilled open." On a door that is only slammed shut, not locked, that is nonsense in 95 percent of cases. A slammed door opens with a card or the right tool, no drilling, no new lock.
- "Call-out fee 90 euros, please pay in advance, in cash." A call-out on its own, in advance, in cash. That is the scheme the trap uses to pocket money before anything has even been done.
If you hear even two of these lines, hang up. You lose nothing but two minutes.
Last week, two calls that show everything
Last week a young woman from Bahnhofsviertel called, completely shaken. She had already dialled an 0800 number. A "technician" had demanded 90 euros just to show up, cash, in advance, before he was even in the car. She had a bad feeling, hung up, and found us. We were there in 25 minutes, the slammed door open in four, 120 euros with an invoice. The difference was not the door. The difference was the number.
That same evening, a second case, the sadder version. An older gentleman from Nordend had already agreed before he reached us. The centre had sent him someone who drilled the slammed door open and fitted a brand new lock on the spot. Invoice at the end: 540 euros. For a door that was not even locked. He called us because he wanted to know whether that was normal. No. It is not. There was nothing left to save except the lesson for next time.
These two calls on one evening show everything. One hung up in time. The other did not.
Why so many fall for it in the evening especially
By day people call more calmly. They have time, they compare, they read the page to the end. In the evening and at night everything is different. Someone is standing in a stairwell in Gallus or Niederrad, it is cold, the phone has 12 percent left, and the pressure is high. In that moment almost everyone taps the first number at the very top. And at the very top sit the ones who pay the most for the ad, not the ones who work the best.
Those exact hours are the dispatch centres' business. They know that nobody compares at night. That is why I hear the worst stories almost always from calls that happened after 10 pm.
Locked out and in a hurry?

What a fair invoice costs in Frankfurt
So you have a figure in your head on the phone to check against. These are real Frankfurt values, not advertising prices.
| Service | By day | Night / weekend / holiday |
|---|---|---|
| Open a slammed door (not locked) | 80 to 150 euros | 150 to 250 euros |
| Open a locked door | 100 to 180 euros | 180 to 280 euros |
| Swap a standard cylinder (part) | 15 to 40 euros | plus labour |
| Security cylinder, e.g. ABUS or BKS (part) | 60 to 150 euros | plus labour |
If someone on the phone quotes double that or refuses to name any figure, you know enough. The full breakdown is in our pricing overview, and what is fair at night and on weekends we explained in our guide to night and weekend prices.
What to ask on the phone, specifically
You do not have to be a pro. Three questions are enough, and you hear from the answer who is on the line.
- "Where exactly are you based, what address?" A real Frankfurt workshop tells you the street and district without hesitation. A centre gets evasive.
- "Roughly what does it cost for a slammed door?" A range comes straight away or not at all. There is no in-between.
- "Will I get an invoice, and can I pay by card?" A yes is an instant relief. Any hesitation about the invoice ends the conversation.
Best of all, note down the name of the person you are speaking to. Just asking for it makes some centres back off.
How to do it right before things go wrong
The most important tip comes from the phone side: save a number before you need it. In an emergency nobody thinks clearly, I see it every evening. Someone standing at 11 pm in front of a slammed door in Bockenheim with a child asleep inside dials the first number they see. That is exactly what the centres count on.
So in a calm minute, ideally now, check whether the number in your phone belongs to a real firm. Is there a Frankfurt address? A 069 number? A price on the page? Three times yes, and you are on the safe side.
If you are not locked out but only pulled shut, it is not a dramatic case anyway, just a simple door opening. Anyone who wants a list of all the warning signs will find it bundled in our guide on spotting a locksmith rip-off. And if it has to be fast right now, you reach our emergency service directly, with no centre in between.
Where you do not have to take only my word for it
This is not something invented by tradespeople annoyed at the competition. The consumer advice centre has warned for years about exactly this pattern, about anonymous middlemen, about prices named only on site, about cash payment without a receipt. Anyone who wants to read it up will find the guidance at the consumer advice centre.
In the end it does not take much to avoid the expensive trap. A calm voice on the phone. A real address. A clear price. If those three things are right, you have already done the most important part, long before anyone is standing at the lock.
