Can Tenants Change Locks for Safety in New Brunswick

Safety & Security New Brunswick 3 min read · published March 09, 2026 Flag of New Brunswick

Living in New Brunswick and worried about personal safety? Many tenants wonder if they can change locks when feeling unsafe or after a security breach. The answer depends on your lease, provincial rules, and whether you follow proper notice and documentation steps. This guide explains practical steps tenants can take to improve security, how to talk to your landlord, what official forms and the Residential Tenancies Tribunal may require, and when replacing or rekeying a lock is reasonable. Wherever possible, aim for clear written agreements and keep records of communication, repairs, and receipts so you protect your rights and avoid disputes.

When tenants may be allowed to change locks

In New Brunswick, tenants do not have an automatic right to change locks without considering the lease terms and provincial rules. If the lock change is for safety after an incident (for example, after a break-in or a violent confrontation), landlords commonly accept reasonable steps to protect tenants. However, you should notify the landlord and retain proof of the incident and any work done. If there is any doubt, contact the Residential Tenancies administration for clarification before making permanent changes.[1]

Detailed documentation increases your chances of success in disputes.

Practical steps to change locks legally and safely

Follow these steps to reduce the risk of conflict or disputes:

  • Contact your landlord immediately to explain the safety concern and state the action you propose, whether a rekey or temporary additional lock.
  • Document the reason for changing the lock with dates, photos, police reports (if any), and written records of conversations or messages.
  • Check your lease for clauses about locks, landlord access, and alterations before proceeding.
  • If the landlord refuses or threatens eviction for taking safety measures, seek advice from provincial tenancy services or tenant help lines.

Temporary measures versus permanent changes

Sometimes a tenant can install a temporary device like a door bar or a keyed chain without altering the landlord's lock. For permanent rekeying or replacing a lock, many landlords will expect the tenant to provide the original key or a copy, or to restore the original hardware at move-out unless you agree otherwise in writing.

Keep all receipts and invoices for locksmith work in case you need to prove costs or request reimbursement.

What to do if the landlord disagrees

If the landlord objects to a lock change, remain calm and follow dispute resolution steps: ask for written reasons, offer to share keys or proof of work, and if needed, apply to the Residential Tenancies process to ask a decision-maker to resolve the issue. The tribunal can weigh safety concerns against lease terms and order remedies if appropriate.[2]

Respond to legal notices within deadlines to avoid losing rights.

Costs and reimbursements

Who pays for a lock change depends on why the change happened and any agreement. If the lock is changed for tenant safety after an emergency, the tenant may pay up front but can later ask the landlord for reimbursement or an adjustment to the security deposit accounting, especially when the landlord caused the unsafe condition. Always get written confirmation if the landlord agrees to reimburse or accept the new lock.

FAQ

Can I change locks without telling my landlord?
Not usually; even for safety reasons you should notify the landlord, document the reason, and provide a copy of the replacement key unless your safety is immediately at risk.
Will changing a lock get me evicted?
Changing a lock alone does not automatically justify eviction, but doing so against lease terms or without following notice and documentation can lead to a dispute or application to the tribunal.
What official help is available if my landlord refuses?
You can contact New Brunswick residential tenancy services or apply to the Residential Tenancies decision process for assistance and to have a binding decision made.[3]

How-To

  1. Review your lease for lock and alteration clauses and note any requirements about returning original keys.
  2. Contact the landlord in writing explaining the safety concern and proposed action; save the message and any reply.
  3. Gather supporting evidence: photos, police reports, dated messages, and receipts from a locksmith.
  4. If the landlord refuses or retaliates, apply to the Residential Tenancies dispute resolution body and submit your documents.
  5. If approved or agreed, ensure both parties sign a short written agreement describing who holds keys and responsibility for future changes.

Key Takeaways

  • Prioritize safety but follow lease rules and give notice when possible.
  • Document incidents and keep receipts to support any future dispute or reimbursement request.
