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

As a tenant in Norway, losing a key can be stressful, especially when a deposit and possible lock replacement costs are involved. This guide explains which documents you should collect, such as written notice to the landlord, receipts from a locksmith and photos of the lock or damage, and how to keep track of expenses. We also explain the deadlines that apply to deposit claims, what counts as valid deductions, and the complaint options available in Norway, including the next steps if you cannot reach an agreement.[1] Examples and practical steps follow in the rest of the article.

Required documents

Gather these documents as soon as possible to make any dispute easier to resolve or to recover your deposit.

  • Formal written notice to the landlord about the lost key and the time of the incident.
  • Receipts for locksmith services, new locks or other direct costs related to the lost key.
  • Photo documentation showing the lock or door before and after, and any damages.
  • Receipt or proof of paid deposit and bank statement from the deposit account if available.
Detailed documentation increases the chance of recovering your deposit in a dispute.

Rights and deadlines

As a tenant you are entitled to an overview of the deposit and any deductions the landlord makes when the tenancy ends. The landlord must be able to document costs for lock replacement or repairs to deduct from the deposit. If you cannot agree, cases can often be brought to the Husleietvistutvalget for a faster decision on deposit disputes in Norway.[2]

  • Notify the landlord in writing as soon as possible after the key is lost.
  • Request a detailed breakdown of any deductions from the deposit.
  • Keep receipts and documentation for at least one year after the tenancy ends, as disputes may arise later.
Respond to requests and deadlines promptly to protect your rights.

How to assess costs and deductions

The landlord may only claim documented and reasonable costs. Normal wear and tear is generally not a valid deduction from the deposit. Costs to change a lock must be necessary and proportionate to the actual risk caused by the lost key.

In most cases, the landlord must document costs to deduct from the deposit.

Key takeaways

  • Notify the landlord in writing immediately and keep a copy.
  • Collect all receipts for locksmith and related expenses as evidence.
  • Check deadlines for refund and complaint to ensure timely action.
