The short answer first, because most people need it standing in the hallway: if you lock yourself out of your rented flat in Essen or lose the key, you, as a rule, pay for the callout, not the landlord. You caused the situation, so you carry the cost of the door opening. If, on the other hand, a lock fails through normal wear, that is the landlord's business. That is the rule of thumb almost everything lines up behind. The rest is detail, and we will go through it calmly now.
One note up front: I advise tenants, I am not a lawyer. What follows is general everyday information from practice, not legal advice for your particular case. In a dispute, a look at your tenancy contract helps and, if it sticks, the tenants' association.
The one rule everything turns on: who caused it?
Tenancy law sounds complicated, but with keys and locks almost everything comes down to a single question. Who set the cause? That decides who pays.
- You lost the key, left it inside, snapped it, or the door fell shut? The polluter principle, you pay for the callout.
- The lock has been jamming for months, the cylinder is worn, the key spins without you doing anything wrong? Normal wear, the landlord carries that.
- You were broken into and the lock was damaged in the process? Then it gets nuanced, more on that below.
The principle is basically common sense. You have to return the flat the way you received it, minus normal signs of use. A lost key is not a normal sign of use, a cylinder tired after fifteen years is.
Case 1: Locked out, key stuck or lying inside
The most frequent call I get in Essen comes from Altenessen, from Steele or from the densely lived-in streets in the city centre: door shut, key inside, you standing outside. The good part, and I say this deliberately to calm you down: this is usually the cheapest of all cases. A door that has fallen shut without the key turned in the lock can often be opened by a skilled fitter in a few minutes without damage. No new cylinder, no damage, just the callout price.
What does that realistically cost in Essen? During the day a simple door opening is typically between 70 and 130 euros on the market. In the evening, at night and at the weekend the price rises, which is normal and fine, as long as it is stated up front. When in doubt, call the emergency service and have a price bracket named on the phone before anyone sets off. Anyone who will not name a price on the phone is the wrong choice.
The tenant carries this cost. The landlord has nothing to do with a door that has fallen shut, even if some people hope so in the first fright. Exception: there is an express agreement or a caretaker service with a spare key, then it runs differently. Do ask before you call a service, a call to the landlord or the property manager can save the whole callout if a spare key is held somewhere.
The expensive beginner's mistake
I see it constantly: panic, the first hit in the search, and at the end there is an invoice for several hundred euros for a simple door that fell shut. Stay calm. Nothing is on fire. A door that has fallen shut is not an emergency in the medical sense, you may take two minutes to pick a reputable provider with a local address and a fixed-price quote.
Case 2: Key lost, and now it gets more expensive
Here it gets more serious, and here the big bills arise. If you lose a flat key beyond recovery, more than the door opening is due. The real question is: does the cylinder, or even the whole locking system, have to be changed?
With a self-contained flat with its own lock the matter is manageable. A new cylinder plus fitting, along with a set of new keys, that is affordable. A good security cylinder is often 60 to 150 euros for the part, with fitting on top.
It gets genuinely unpleasant in a building with a central locking system, as fitted in many larger housing estates in Katernberg or Holsterhausen. If your lost key also opens the front door, the cellar and the bin store, then with a real risk of misuse the replacement of the entire system can be on the table. And that quickly runs into the thousands.
Reassurance at this point, because fear is often used against tenants here: replacing a whole locking system is not automatically due just because a key is gone. In the practice of many courts a concrete risk of misuse must exist. A key left somewhere on a train with no address usually does not create that risk as strongly as a key ring stolen together with an ID card and address. Do not let a complete system be pushed on you hastily. Ask in writing what the concrete danger consists of.
What liability insurance steps in for
One sentence that saves many people money: your private liability insurance covers, in many cases, the loss of other people's keys, so also the key to the rented flat and to the locking system. Whether this so-called key clause is in your contract is stated in the terms. Check it before you pay. I have seen people carry four-figure sums themselves when their liability cover would have taken it all.
Locked out and in a hurry?

Case 3: Break-in and a damaged lock
If you were broken into and the lock was levered or drilled open, the situation is different. The damaged flat door is part of the rented property, and restoring it is in principle the landlord's business. But you should report it to the police at once and notify the property manager of the damage, ideally in writing with photos. For your stolen belongings, in turn, your own contents insurance is responsible, not the landlord.
Important on the night of the break-in: the flat has to be lockable again. A lock replacement or a temporary securing is then urgent, and you settle the costs afterwards with the landlord and the insurer. Keep every invoice. How high the burglary risk should even be rated you can read up neutrally in the police crime statistics, rather than being led by scaremongering.
And who actually pays for the spare key?
A small, frequent question to close the cases. If you simply want an extra key for your partner or the children, you pay for the key cutting yourself. But careful: with a secured locking system you cannot just have one cut at the next heel bar, the blanks are restricted and need a security card. That runs through the landlord or the management. Cut a key secretly and return the flat with fewer keys than the contract states, and that can get expensive.
The most frequent questions from my advice sessions
I locked myself out, do I have to ask my landlord before calling someone? You do not have to, but it often pays. If the property manager or caretaker has a spare key, you save the whole callout. A quick call costs nothing.
After I lost my key the landlord wants a new locking system for 2000 euros. Do I have to pay that? Not automatically. A concrete risk of misuse must exist, and the damage must be reasonable. Have the necessity justified in writing and check your liability cover. In doubt, bring in the tenants' association.
My cylinder has been jamming for weeks, who pays for the swap? With normal wear, the landlord. Report the defect in writing, set a deadline. Do not secretly repair it yourself and then deduct it from the rent without having reported the defect first.
May the locksmith charge triple at night? A night and weekend surcharge is permitted and usual. Extortion and coercion are not. Have the price named beforehand and sign nothing under pressure. You often spot dubious providers by the missing fixed price on the phone.
In short
Remember the one question: who caused it? Locked out and lost keys you pay, normal wear and break-in damage to the lock the landlord carries. Stay calm with a door that fell shut, get a fixed price, and with a lost key always check your liability cover first before paying for an expensive locking system.
