Deposit & blocked account 2 min read · published September 11, 2025

When a key is lost, many tenants quickly wonder who pays and how the security deposit is affected. Finland has clear rules on tenancy responsibilities, but common mistakes increase the risk of deposit deductions or compensation claims. This guide helps tenants understand practical steps: how to report the loss, document expenses, request invoices and negotiate with the landlord. It also explains when deductions from the deposit can be made and how disputes are resolved formally. We stay practical so you can protect your rights and reduce costs as quickly as possible in Finland situations. The content also covers how to order a temporary key, who is responsible for locksmith costs and when to seek advice from judicial authorities or the Consumer Advisory Service. The instructions are based on Finnish legislation and official guidance.

What to do immediately

Notify the landlord or property manager in writing about the loss and request an acknowledgment. The Act on Residential Leases sets out the parties' responsibilities, so make the notification promptly and keep copies [1].

  • Notify the landlord and property manager in writing.
  • Request lock replacement or spare key arrangements if security is compromised.
  • Check how the security deposit may be affected by possible charges.
  • Document expenses, receipts and timestamps of the event.
Detailed documentation improves your chances in dispute resolution.

Deposit and liability for costs

Handling of the security deposit depends on whether the landlord can demonstrate damage or extra costs. If lock replacement or key copying results from tenant negligence, the landlord may seek compensation from the deposit or separately. Keep receipts and quotes to demonstrate reasonableness if needed.

Avoid verbal agreements on compensation; request a written statement.

How disputes are resolved

First try to negotiate with the landlord and ask for an itemized statement of charges. If negotiation fails, you may need to seek resolution through official channels such as the Consumer Advisory Service or district court [2].

  • Contact the Consumer Advisory Service or the Competition and Consumer Authority (KKV) before legal action.
  • Keep all messages, receipts and photos as evidence.
  • If necessary, prepare to present the case in district court.
Respond promptly to any official notifications to avoid legal disadvantages.
