First things first, because at night there is no time for long texts. A serious 24-hour service in Frankfurt gives you a price range on the phone, states a company name with an address, and sends someone from the region, not from a call centre in Berlin or Hamburg. Anyone who will not name a price is out. The rule really is that simple.
I have worked the night shift for twelve years and advise tenants on their rights on the side. Most of the complaints that reach me are not about the lockout itself. They are about the invoice afterwards.
How do I spot a serious emergency service at night?
There are five points you can clear up in thirty seconds on the phone. Quickly, before you send anyone out.
- Is a price range on the website, or stated on the phone? Even at night a simple slammed door should not cost more than 150 to 250 euros.
- Is there a real company address in Frankfurt or the surrounding area, not just an 0800 number from a call centre?
- Before any drilling, is it explained why drilling is needed? A slammed, unlocked door needs no drilling.
- Do they accept card, or insist on cash? Cash-only is a warning sign.
- Do you get an invoice with a tax number and company address? If not, walk away.
These five questions sound trivial. They are not. In twelve years I have barely seen a case where a firm answered all five points cleanly and then ripped someone off in the end. The other way round, often. Anyone who dodges on the phone will dodge on the invoice too.
The 0800 trap and the "head office"
Many of the numbers that sit at the top of the search results at night belong to no locksmith at all. They belong to a referral office. It sits somewhere, sometimes not even in Germany, and sells your job to whoever happens to be nearby. The middleman takes a commission, and that ends up on your bill. That is where the surcharge comes from.
You can often spot it in the conversation. They ask you for the district, but not for the exact problem. They name no company. They say "a technician is nearby", but nobody can say who that is. This is exactly the moment to hang up.
What may a 24-hour emergency service in Frankfurt cost?
Let us talk numbers, because that is what it comes down to in the end. Here is my honest range from practice, as of 2026.
| Service at night/weekend | Fair price |
|---|---|
| Slammed door, not locked | 150 to 250 euros |
| Locked door opened without drilling | 180 to 320 euros |
| Standard cylinder swap (part) | 15 to 40 euros plus labour |
| Security cylinder swap (part) | 60 to 150 euros plus labour |
| Call-out within Frankfurt | often included, otherwise 20 to 40 euros |
During the day a simple door opening sits closer to 80 to 150 euros. The night surcharge is legitimate, because someone gets up at three in the morning and drives out. What is not legitimate is a base price of 39 euros on the phone that suddenly becomes 400 on site.

The most common night-time trick
A low price on the phone, then surcharge after surcharge on site. Call-out, night supplement, special tools, wear material, disposal, weekend flat rate. Each item sounds plausible on its own. The final bill is three or four times the quote.
The second trick is needless drilling. Your door is merely slammed, so not locked, and the man starts drilling anyway. A professional pushes a slammed door back open with a card or a slim hook in minutes. Whoever drills destroys your cylinder and then sells you a new one, often a cheap one for serious money. That is not a repair, that is a sales pitch with a drill.
Have the final price confirmed before work starts. Better still, have the price list shown to you and take a photo. Anyone who refuses has something to hide. How these scams work in detail is covered in our guide on spotting locksmith rip-offs.
Two nights from practice
Two weeks ago, three in the morning, a customer in Bahnhofsviertel. Another service had promised her 39 euros on the phone and demanded 480 on site, the door was merely slammed. She left the man standing and called us. We pushed the latch back in four minutes, 160 euros with the night surcharge, done. The difference is not the tools. The difference is the honesty on the phone.
Last month in Bornheim, a Sunday around midnight, a completely different story. A young man really had locked himself out, key still in the lock on the inside. Here a card alone would not do it. I told him in advance what it would cost, 280 euros, and why. He agreed, I opened without drilling because the cylinder was an older BKS model that can be picked with the right tool. A dishonest firm would have drilled at once and sold him a new cylinder. That is the whole difference between a tradesperson and a salesman.
Locked out and in a hurry?
Price quoted up front, vetted partner business, ~22 minutes on site.
Preparation beats panic
A tip I give everyone costs nothing and saves a lot. Note down today, while calm, in daylight, the number of a reputable firm near you and save it in your phone. Do it now, not later.
At three in the morning in front of your own door nobody is in a state to compare calmly. You are cold, you are tired, perhaps the child is inside. That panic is exactly what dishonest providers count on. Whoever is prepared calls the right one directly, instead of dialling the first advert from the search engine.
One more practical point for tenants, and that is my actual field. If possible, leave a spare key with someone you trust. A neighbour, your parents, a good friend in Nordend. At night that is often faster and always cheaper than any emergency service.
Who actually pays, tenant or landlord?
This question comes up every week, and it is rarely answered correctly. The basic rule under tenancy law. If you have merely locked yourself out and the door is opened, you pay for that yourself, it is not a defect of the flat. If the key is lost and a whole locking system therefore has to be changed, it can quickly get expensive, and as a rule that too is borne by whoever lost the key.
If, on the other hand, a lock fails through normal wear, say because the cylinder sticks after years, that is the landlord's matter. In case of doubt it pays to call the property management before you order an emergency service at night at your own cost. For disputed cases the tenants' association is a good place to start, and I say that from twelve years of advising.
If after an inflated emergency bill a new cylinder is due anyway, take a calm look at lock replacement. During the day, planned and with a clear price, it is far cheaper than anything that happens under pressure at night.
Quick answers for the night
Do I have to accept the phone price if it is higher on site? No. A price clearly higher than the one named on the phone is not automatically binding. Have the final price confirmed beforehand and insist on an invoice.
Is an emergency service allowed to drill my door? Only if there is technically no other way, and with a slammed, unlocked door that is practically never the case. Drilling is the last resort, not the first.
How fast is a good emergency service there? In Frankfurt, from the region, usually in 20 to 40 minutes, depending on the district and traffic. Anyone who promises "in five minutes" is either already in the car hunting for jobs or telling you what you want to hear.
Bottom line. A good emergency service takes the stress off you at night instead of adding to it. Ask for the price, insist on an invoice, and let nobody drill who does not have to. In a real emergency you reach us around the clock through the emergency service, and if you have questions in advance, gladly through contact.
