Lost Keys and Deposit: Tenants in Norway

Deposit & blocked account 3 min read · published September 11, 2025

As a tenant in Norway it is common to feel uncertain when keys go missing or when the security deposit is to be returned. This guide explains common mistakes tenants make — from not reporting the loss quickly enough to lacking documentation and receipts — and gives concrete advice on what you should do. You get practical steps for notifying the landlord, securing evidence, calculating deadlines and claiming the deposit back. We also show how you can contact the Tenancy Disputes Tribunal (HTU)[2] or the courts if the case is not resolved. The language is simple and aimed at tenants without legal background. Also read what can be deducted from the deposit, how to secure keys when moving, and when it pays to seek legal aid.

What to do first

When you discover a key is lost or if you believe the deposit may be unfairly withheld, follow these immediate steps to protect your rights.

  • Notify the landlord in writing with the date and explanation.
  • Change the lock or agree with the landlord who will pay for lock replacement.
  • Secure documentation: take photos, keep receipts and make a short written log.
  • Request an overview of the deposit account and any deduction claims.
  • Obtain written cost estimates for lock changes or repairs if the landlord claims costs.
Report lost keys to the landlord in writing as soon as you discover it.

Common mistakes tenants make

Several mistakes often lead to unnecessary loss of deposit or disputes. Be aware of these points.

  • Failing to document the condition or cleanliness at move-in and move-out.
  • Not notifying in writing within a reasonable time about loss or damage.
  • Accepting verbal agreements on deposit deductions without written assessment or receipts.
  • Leaving locks unchanged after a lost key without clarifying who has keys.
Keep all receipts and communications to be able to document your claim in a dispute.

The Tenancy Act and complaint routes

The Tenancy Act governs many issues around deposits, liability and deductions.[1] If you cannot reach an agreement with the landlord, you may file a complaint with the Tenancy Disputes Tribunal (HTU)[2] or bring the case before the conciliation board or district court.[3] HTU can provide quick decisions in many rental disputes, sometimes at no cost to the tenant. Documentation and clear communication increase the chances of a good outcome.

Deadlines may vary; ask for written clarification and follow up within a reasonable time. Documentation of handover timing and condition is important.
