Deposit (security) & payment proofs 3 min read · published September 11, 2025

As a tenant in the Netherlands, lost keys can be unexpected and costly. You may wonder who is responsible for replacing locks, whether the landlord may use the deposit, and what steps to take to avoid unfair charges. This article explains in plain language your rights and obligations when keys are lost or stolen, how to limit damage and costs, which documents are useful, and when you can involve the Rent Tribunal[2] or the legal aid desk. We provide practical steps for notifying the landlord, obtaining quotes for replacement, and tips for reclaiming your deposit so you are better prepared.

What does lost keys mean for your deposit?

Lost keys can affect the deposit (security sum) if there are costs for replacing locks or changing the locking system. Under the Civil Code Book 7 (tenancy law), costs may only be deducted if they are reasonable and demonstrable and proportionate to the damage[1]. Therefore, always ask for an itemised bill of costs and keep quotes and payment receipts.

In most tenancy agreements, the landlord may only deduct reasonable costs from the deposit.

Who pays for replacement and damage?

  • If you lost the keys due to your own fault, reasonable replacement costs may be deducted from the deposit (deposit).
  • In case of theft, it is wise to file a police report; sometimes insurance or the landlord covers only verifiable costs (deposit).
  • The landlord must not make an unspecified flat deduction from the deposit; always request an itemised explanation and proof of costs (deposit).
Notify your landlord immediately about the loss and record the date and time of notification.

What can you do: steps for tenants

  1. Report the loss in writing to the landlord and note the date of notification (file).
  2. Request at least one or two quotes for replacing locks and ask for a breakdown of the work (repair).
  3. Keep evidence: emails, photos of damage, receipts and correspondence with the landlord (evidence).
  4. Only pay reasonable costs and ask for reimbursement if the landlord wrongly deducts amounts from the deposit (deposit).
  5. If necessary, involve the Rent Tribunal or bring the case to the subdistrict court; first try to resolve the matter in writing (court).
Respond within legal deadlines to preserve your rights.
