As a tenant in Austria you may often wonder whether and how you are allowed to change the apartment lock yourself.

This guide explains clearly when a lock change is permissible, which steps are necessary, how to inform the landlord and which documents and key handovers are important. You will also learn how to protect yourself if the landlord requests a change and which authorities or courts are competent in case of dispute. Read the practical tips before replacing a lock so you know your rights and duties as a tenant and act with legal certainty.

When is a lock change allowed?

A lock change is allowed if the lease or the law permits it or if there is an immediate danger to people or property. If the contract has no explicit provision, the usual rule is: inform the landlord before changing and request consent; if the landlord is unreachable in an emergency you may act yourself, but you should document your actions.[1]

Document the time, reason and who received keys.

Practical steps before changing the lock

  • Keep keys (keys) safely.
  • Obtain the landlord's written consent in form (form).
  • Collect and secure photos and documents (evidence).
  • Return all keys (move-out) when vacating.
Without consent you may face claims for damages or contractual penalties.

How-To

  1. Check the lease for clauses about replacement (form).
  2. Notify the landlord in writing and set a reasonable deadline (form).
  3. Hire a locksmith or change the lock yourself; keep a copy of the key (keys).
  4. Create a handover protocol, take photos and keep receipts as evidence (evidence).
  5. In persistent disputes consider legal action before the district court.[2]
District courts are often the first instance for tenancy disputes.
