Tenant guide: lost keys and deposit in Sweden

Deposit & payment proof 2 min read · published September 11, 2025

Losing a key can be stressful for a tenant, especially when a security deposit and proof of payment are involved. This guide for tenants in Sweden explains the steps to take immediately after losing a key, how to document expenses, when a landlord may deduct from a deposit and how proof of payment can support your case. We also describe how to contact the Rent Tribunal or the Enforcement Authority if a dispute arises, typical deadlines to be aware of and which pieces of evidence are most useful. The information is practical and easy to follow without legal background. In many cases locks must be changed if intrusion risk increases, and the landlord may request compensation for reasonable costs. Keep receipts, take photos and request written confirmation for payments.

What to do when you lose a key

Start by checking if you have spare keys or obligations stated in your lease. Contact the landlord immediately to inform them of the loss; this reduces misunderstandings and shows you are acting promptly.

  • Contact the landlord quickly and explain the situation.
  • Assess whether locks need changing for security and discuss who pays.
  • Keep receipts and proofs of payment for all expenses.
  • Request written confirmation from the landlord regarding deposit use and reimbursement.
Keep receipts, photos and correspondence immediately.

Deposit and deductions

The security deposit may be used to cover damages or unpaid rent under the Swedish Land Code, Chapter 12 (Tenancy), where applicable[1]. The landlord may only deduct actual costs and should be able to provide receipts or other proof. If you believe a deduction is incorrect, request a detailed written account and keep all proof of payment.

Disputes and next steps

If you cannot agree, the Rent Tribunal can decide the issue. Application forms and information are available via the courts[2]. If a decision becomes enforceable and there are unpaid claims, the Enforcement Authority can be used to collect debts[3].

Respond to formal demands within deadlines to preserve your rights.
