Changing Locks and Tenant Security Rights in NS

Tenant Rights & Responsibilities Nova Scotia 4 min read · published March 09, 2026 Flag of Nova Scotia

Tenants and renters in Nova Scotia often worry about who can change locks, when it is allowed, and how to keep their home secure. This guide explains tenant rights and practical steps around changing or rekeying locks, what your lease may require, when a landlord can access your unit, and how to document safety concerns. You will also learn how to give written notice, when an emergency justifies immediate lock changes, and how to bring a dispute to the provincial Residential Tenancies Program if needed. The language is plain and focused on actions you can take to protect yourself and respond effectively while staying within Nova Scotia rules.

What Nova Scotia law says about locks and security

The governing legislation for most landlord-tenant matters in the province is the Residential Tenancies Act. The provincial body that handles disputes and applications is the Residential Tenancies Program.[1][2] Tenants generally have a right to reasonable privacy and quiet enjoyment, but leases and local rules can affect when you can change locks or who must hold spare keys.

Tenants are entitled to basic security and privacy in their rental home.

Can a tenant change the locks?

In many cases a tenant may change or rekey a lock for safety, but you should first check your written rental agreement and any building rules. If the lease specifically prohibits changing locks or requires a copy of keys be given to the landlord, follow the lease or try to negotiate a written exception. If the landlord denies reasonable security changes after you explain a safety concern, you can collect evidence and apply to the Residential Tenancies Program.[1]

Keep at least one copy of any new key in a secure place in case of emergencies.

When is it acceptable to change locks without landlord permission?

  • In an immediate emergency after a break-in or threat to safety, you may change locks to protect yourself.
  • If you give written notice and the landlord does not act within a reasonable time, you can document the refusal and seek a remedy.
  • If locks are old or broken and the landlord will not repair them, you may replace them but keep a record and offer the landlord a copy of the new key unless the lease lawfully forbids it.
Changing locks without documenting the reason and notifying the landlord may create disagreements about access or deposits later.

How to document security concerns

Good documentation improves your position if you need a formal remedy. Photographs, dated notes of incidents, and written requests to the landlord create a clear timeline.

  • Take dated photos of any damage after a break-in or forced entry.
  • Send written requests (email or letter) asking for repairs or lock changes and keep copies.
  • Record the dates and times of phone calls and who you spoke with about the issue.
Detailed documentation increases your chances of success in disputes.

What to do if the landlord insists on keeping keys

Some landlords keep spare keys for lawful reasons such as repairs and safety. If you are uncomfortable, ask for written limits on when the landlord can enter and request prior notice except in emergencies. If access becomes excessive or abusive, gather your evidence and apply to the Residential Tenancies Program for a remedy.[1]

When to involve the Residential Tenancies Program and what forms to use

If negotiation fails, you can apply to the provincial office that handles tenancy disputes. The typical steps include filing the appropriate application or complaint, paying any fee if required, and attending a hearing or mediation. The provincial website explains the application process and the forms to use when seeking orders related to repairs, safety, or unlawful entry.[3]

Respond to notices and applications promptly to protect your rights.

Practical examples

  • If you are locked out after a roommate leaves, change the lock for safety and offer a spare to the landlord if your lease requires it.
  • After a forced entry, take photos, call the police if needed, change locks, and notify the landlord in writing.
  • If the landlord refuses a safety repair, send a written request and then file the residential tenancies application described on the provincial site.

FAQ

Can I change the locks without the landlord's permission?
Yes in an emergency or for safety, but check your lease, document the reason, notify the landlord in writing and keep a spare key if the lease requires one.
When can a landlord enter my unit?
A landlord normally must give reasonable notice and can only enter for allowed reasons such as repairs, inspections, or showing the unit; they may enter without notice only in emergencies.
What if my landlord refuses to fix a broken lock?
Document the request, send written notice, and if the landlord still refuses you can apply to the Residential Tenancies Program for an order requiring repairs.
Do I have to return keys at the end of my tenancy?
Yes. At the end of tenancy you must return keys unless you have a different written agreement with the landlord.

How-To

  2. Document the security issue with photos and dated notes explaining incidents.
  3. Send a written notice to the landlord asking for lock repair or replacement and keep a copy.
  4. If the landlord does not act in a reasonable time, apply to the Residential Tenancies Program for dispute resolution.
