Lost apartment keys in Vienna — landlord, insurance, and locksmith steps

If you have lost your apartment keys in Vienna, stay calm and act quickly. First, call RIVA's 24-hour phone line (+43 1 969 06 38). Dispatch availability and timing are confirmed during the call; a simple daytime opening starts from €90 incl. VAT and, when dispatched, arrival is usually within 15-40 minutes. Then inform your landlord, because if the keys are truly lost the cylinder may need to be changed for security, and your liability insurance may cover the cost.

Step 1: Call the 24-hour phone line

The first priority is getting back into your home. RIVA's unlocking service in Vienna has a phone line available 24 hours. A simple daytime opening starts from €90 including VAT; the expected price range, dispatch availability and timing are confirmed before anyone drives out. When dispatched, a technician usually reaches addresses across Vienna in 15 to 40 minutes, depending on traffic and workload.

When you call, have the following ready:

• Your address and the relevant door (apartment entrance, building door, or garage)
• A way to prove you live there — your Meldezettel (registration certificate), a photo ID, or a rental contract. This is standard practice in Austria and protects against unauthorised access.
• A brief description of the lock if you know it (cylinder, multipoint, security door)

If your keys are simply locked inside the flat, the locksmith opens the door and you are done — no lock change required. If your keys are genuinely lost, you need to go further.

Step 2: Inform your landlord or property manager

As soon as you can, contact your landlord (Vermieter) or the building management (Hausverwaltung). They may hold a spare key, which can save you an emergency call-out. More importantly, they need to know that keys to their property are missing.

This step is especially critical if your building uses a master key system (Schliessanlage). In a Schliessanlage, your apartment key also opens shared doors — the building entrance, cellar, laundry, or garage. A lost key in such a system is a security risk for the entire building, and the landlord or Hausverwaltung must coordinate any cylinder change. Costs in these cases can be higher because multiple cylinders or the whole system may need attention.

Step 3: Change the cylinder if the keys are truly lost

If there is any chance your keys were lost outside the apartment — dropped on the street, left in a cafe, or stolen — you should have the cylinder changed. Otherwise, whoever finds the keys could simply walk into your home, and your insurance may refuse to cover a later break-in if you did not act.

RIVA carries out lock changes in Vienna with a transparent price range agreed before the work. Depending on the cylinder and parts available, the technician may be able to swap it on the same visit as the unlocking, so you regain access and secure the door in one appointment. This is also a good moment to upgrade to a security cylinder with a key card, which prevents unauthorised key duplication in future.

Step 4: Check your insurance

Many expats are unaware that private liability insurance (Haftpflichtversicherung) in Austria frequently covers the cost of replacing locks and keys when they are lost. Some household contents policies (Haushaltsversicherung) also include this.

To claim:

1. Keep the locksmith invoice. RIVA issues a clear, itemised bill suitable for insurance submission.
2. Report the loss to your insurer promptly — most policies require notification within a few days.
3. Ask your landlord for any additional costs they intend to charge (for example, if a Schliessanlage is involved) and pass these on to the insurer as well.

If you do not yet have Haftpflichtversicherung, this situation is a good reason to arrange it — it is inexpensive and covers far more than lost keys.

Austrian specifics expats should know

• Meldezettel as proof of residence. When a locksmith opens a door in Austria, they will ask for proof that you live there. Your Meldezettel (the registration certificate you receive when you register your address) is the standard document. A photo ID with matching address or a rental contract also works.
• Locked out vs. lost. The distinction matters for both security and cost. Locked-out calls are simpler and cheaper; lost-key situations require a cylinder change and often insurance involvement.
• Schliessanlage buildings. If your building has a master key system, you cannot change the cylinder yourself or through an independent locksmith without the Hausverwaltung. Always involve them first.
• Tenant rights. If you rent, you are generally allowed to change the cylinder as long as you keep the old one and reinstall it when you move out. See our guide for renters changing the lock in Vienna.
