Slammed door in a Brussels rental: tenant or landlord, who pays?

The general principle in Belgian law

The Belgian Civil Code clearly distinguishes two repair categories in a rental:

• Minor tenant repairs (art. 1754 / 1755): tenant's responsibility
• Major repairs / wear and tear: landlord's responsibility

Locksmith work after a slammed door (no break-in, no material damage) almost always falls in the first category — except for the specific cases below.

Classic slammed door — tenant pays

You step out to take the bins and the door slams behind you with the key inside — that's a tenant action. The opening, and possibly cylinder replacement if the locksmith had to drill, are on you. Expect €100-200 during the day, €180-320 at night — see our pricing guide.

Cases where the landlord pays

1. Faulty lock not caused by tenant

If the door slammed because the mechanism was already damaged (broken spring, poorly fixed strike, age-seized cylinder), the landlord bears the cost. Evidence: photos of the dismantled lock, written locksmith report noting "wear" or "pre-existing mechanical fault".

2. Cylinder installed by landlord before move-in

If the landlord installed the cylinder before your arrival and it fails after 3 months of tenancy, that's an equipment failure — their cost. If you installed it yourself, it's yours.

3. Door damaged by identified third party (neighbour, break-in attempt)

A break-in attempt is covered by home insurance, not by the tenant personally. The landlord or their insurer takes over. Demand a police report and keep it.

Special case: common-area front door in a co-ownership

In Brussels, many apartments have two doors: a common-hall entrance (often co-ownership property) and a private door. For the common door the syndic handles it through the co-ownership account — not you, not the individual owner.

Costly mistakes

• Accepting drilling without photos: ask the locksmith to photograph the lock before and after. Without photos, impossible to prove the lock was faulty.
• Not notifying the landlord: within a reasonable delay (24-48h max), send SMS or email. Lack of information can shift the cost to you.
• Replacing the cylinder without landlord's consent: the landlord is entitled to a key. Without prior agreement on replacement, they can refuse reimbursement and demand the original cylinder back.
• Paying cash without invoice: impossible to recover VAT and prove the amount to the landlord or insurer.

The right-reflex checklist

1. Notify the landlord in writing (SMS, email, WhatsApp) describing the issue
2. Request three written quotes if not urgent (opening can wait until tomorrow)
3. In real emergency, call a locksmith who provides invoice and photos — see our emergency locksmith
4. Keep invoice + photos + messages for at least 1 year
5. If disagreement: go through the commune's rental mediation before court action
