A Broken Lock in a Rental: Who Pays?
A broken lock on your rental flat in Germany can feel urgent and stressful, especially if you're not sure whether your landlord or you should cover the cost. The answer depends on how the lock broke, the terms of your lease, and German tenancy law—but the practical steps to take right now are clear.
This guide explains your rights and responsibilities as a tenant, how to document the problem, and when to contact your landlord. If you need immediate help, our English-speaking hotline can connect you with a certified local locksmith and advise on next steps.
German Tenancy Law: Normal Wear and Tear vs. Damage
Under German rental law (Mietrecht), your landlord (Vermieter) is responsible for keeping the flat in a rentable state—which includes functional locks on all exterior doors and main entry points. This is part of their duty to maintain the property (Instandhaltungspflicht).
The key distinction is whether the lock broke due to normal wear and tear or tenant negligence:
- Normal wear and tear: If the lock simply wore out after years of use, the landlord pays.
- Tenant damage: If you broke the lock through misuse, rough handling, or accident, you may be liable.
- Defects present at move-in: If the lock was already faulty when you moved in, the landlord is responsible.
Your Mietvertrag (lease agreement) should clarify minor repairs and who pays for what. In many cases, tenants pay for repairs under €120–150, but this varies by contract and region. Check your lease—it often says something like 'Kleinreparaturen' (small repairs)—but even then, locks and security devices are often excluded because they're essential to the flat's habitability.
What to Do Immediately: Document and Notify
Speed matters when a lock is broken. You have a security and safety interest, and your landlord needs to know right away.
- Take photos and videos: Show the broken lock from multiple angles, any visible damage, and the date on your phone or camera.
- Write to your landlord: Send an email or letter (Schriftform) describing the problem, when it happened, and how. Keep a copy for your records. This creates a paper trail if disputes arise later.
- Note the date and time: Record exactly when the lock stopped working and whether it was sudden or gradual.
- Mention security concerns: If the lock is on an exterior door or entry to a common area, stress that the flat is not secure and needs urgent repair.
- Request a timeline: Ask your landlord when they will arrange a repair. German law generally expects repairs to happen 'within reasonable time' (angemessene Frist)—usually a few days for security-related issues.
Most landlords will act quickly if you're professional and clear. Some will arrange a locksmith directly; others may ask you to get quotes first.
Who Pays: Your Lease, the Landlord, or You
In most German rental situations, the landlord pays for lock repairs because locks are essential to the property's security and habitability. However, your specific contract and circumstances matter.
- Exterior doors and main entry locks: Almost always the landlord's responsibility.
- Interior door locks or window locks: May fall under tenant responsibility, depending on the lease.
- Locks you damaged: You typically pay if the damage was caused by misuse or negligence—for example, forcing a stuck lock or dropping a key in it.
- Locks you had installed: If you added a lock for your own use (a deadbolt on your bedroom door, for instance), you usually pay if it breaks.
- Repeated faults in the same lock: If a lock keeps breaking without obvious tenant damage, the landlord covers it as a persistent defect.
If your lease says tenants pay for small repairs up to a certain amount, the landlord may try to pass the cost to you. However, courts in Germany often rule that locks and security features are not 'small repairs'—they're essential services. If you're asked to pay and you disagree, you can withhold the amount from your next rent (Mietminderung is complex, so seek advice first) or pay and request reimbursement.
What Happens If Your Landlord Doesn't Respond
If your landlord ignores requests to repair the lock, you have legal options—but they require careful steps to protect yourself.
- Send a formal notice: After your initial request, send a registered letter (Einschreiben mit Rückschein) giving your landlord a reasonable deadline—typically 3 to 7 days for a security issue.
- Mention the defect (Mangel): Use this word in writing; it triggers legal obligations on your landlord's side.
- Right to self-help (Selbsthilfe): In Germany, if your landlord fails to repair essential items, you can arrange repairs yourself and deduct the cost from rent—but only after formal notice and a reasonable waiting period. Keep all receipts and invoices.
- Rent reduction (Mietminderung): A broken exterior lock can justify a temporary reduction in rent while it's unfixed, but the percentage depends on how much the property is unusable. Consult your Hausrat (household contents) insurance provider or a tenant advice centre first, as rules are strict.
- Document everything: Photo dates, email timestamps, registered letter receipts—all are evidence if the dispute reaches a court or insurance claim.
Most landlords respond within days to security issues. If yours doesn't, there may be a language barrier, a missed message, or genuine oversight—not malice. A polite follow-up call (or email to their property manager) often resolves it.
Your Insurance and When to Call a Locksmith
Before you assume your landlord will pay, check your own Hausrat (household contents insurance) and Haftpflicht (liability insurance). Neither typically covers locks, but it's worth confirming—especially if you caused the damage.
If the lock is broken and you cannot secure the flat, you may need to arrange an emergency locksmith yourself for safety reasons. In that case, get a written quote first if possible, and keep the invoice. Include a copy in your letter to the landlord, along with a request for reimbursement. Most landlords will reimburse urgent repairs if you acted reasonably.
A certified local locksmith will assess whether the lock can be repaired or needs replacement, and they'll provide a transparent cost breakdown on a written order form. They can also advise whether the lock failure was due to wear, damage, or a defect in the mechanism—useful information for your landlord conversation.

Frequently asked
Can my landlord force me to pay for a broken lock repair?
Not usually for exterior doors or main entry locks—these are the landlord's legal responsibility under German tenancy law. If your lease says you pay for small repairs, a lock repair may still be excluded because it's essential to security. If your landlord insists and you disagree, ask for the clause in writing and consider consulting a tenant advice centre or Mieterbund before paying.
How long does my landlord have to fix a broken lock?
German law expects repairs to happen 'within reasonable time'—for a broken exterior lock, that usually means a few days. If it takes longer than a week without good reason, you may have grounds to claim a rent reduction or arrange the repair yourself and deduct costs. Always give written notice first.
What if the lock was already broken when I moved in?
The landlord is responsible. You should have reported it during the move-in inspection (Wohnungsübergabe). If you didn't, report it now in writing with photos; if the lock is in the original condition, the landlord has no excuse. Keep documentation of when you reported it.
Can I withhold rent if the lock isn't fixed?
Rent withholding (Mietminderung) is possible but legally complicated in Germany. You cannot simply stop paying; you must follow formal notice procedures and document the defect clearly. It's safer to pay rent as usual and claim reimbursement in writing, or seek advice from a tenant organization before taking this step.
Who pays if I accidentally broke the lock?
You do, if the damage was due to your negligence or misuse. However, if the lock was already weak or defective, the landlord may share liability. Be honest with your landlord—many will not make a fuss over an accident if you report it quickly and arrange repair yourself.
Do I need written permission from my landlord to call a locksmith?
If the flat is not secure, you can call a locksmith immediately for safety—it's a justified emergency measure (notwendige Instandhaltung). Inform your landlord in writing the same day. If it's not an emergency, it's polite to ask first, but if your landlord is unresponsive, you can proceed after formal notice.
