Alberta Rules on Tenant Lock Changes and Rekeying

Safety & Security Alberta 4 min read · published March 09, 2026 Flag of Alberta

Many tenants worry about locks and rekeying when moving into or living in rental homes in Alberta. This article explains tenant rights and landlord responsibilities in clear, practical terms: when you can change a lock, when you must notify the landlord, and how to handle safety concerns without creating legal problems. It covers common situations such as lost keys, domestic violence, shared locks, and when landlords require rekeying between tenancies. You'll learn how to document changes, what official forms or dispute services to use, and the steps to take if a landlord objects. The goal is to help renters protect their security while following Alberta tenancy rules.

Can tenants change locks or rekey a rental unit?

In Alberta, tenants may change locks for safety reasons, but they should follow the lease and applicable rules. If the lease explicitly forbids changing locks, discuss options with the landlord first. If a lock change is for immediate safety (for example, lost keys or personal safety concerns), tenants can act to secure themselves, then notify the landlord promptly. Always keep documentation of why and when you changed a lock and who performed the work.

Keep dated photos and receipts for any lock or locksmith work you arrange.

When must a tenant notify the landlord?

Notify your landlord as soon as possible after changing or rekeying a lock, and provide replacement keys unless the landlord has agreed otherwise. Failure to give the landlord reasonable access keys can lead to disputes. If a lease requires prior written notice for alterations, follow that process unless the change was needed to protect personal safety.

If you change a lock without arranging key access, the landlord may claim you obstructed reasonable access.

When can a landlord require rekeying?

Landlords commonly rekey or change locks between tenancies to ensure security for new renters. They may also require rekeying if they can demonstrate a safety or security reason. If a landlord asks you to pay for rekeying during a tenancy, check whether your lease or provincial rules allow the charge and whether it is reasonable.

Common scenarios and practical steps

  • Lost keys: change or rekey the lock and give the landlord one copy of the new key unless you agree otherwise.
  • Safety risks (for example, domestic violence): secure the unit immediately and notify the landlord; keep proof of the safety issue.
  • Lease terms: check your lease for any clauses about lock changes or tenant alterations before making non-urgent changes.
  • Documentation: keep photos, receipts, and written notices showing when and why the lock was changed.
  • Disputes: if the landlord objects, try mediation or file an application with the provincial dispute service listed below[2].

Paying for lock changes and who keeps keys

Who pays depends on the reason: tenants usually pay for lock changes made for their own convenience or safety, while landlords may pay when changes are for building security or between tenancies. If a landlord requires a tenant to pay for rekeying, request an itemized receipt and confirm whether the cost is reasonable. Always provide at least one key to the landlord unless a safety plan or written agreement says otherwise.

Open communication and written agreements reduce the chance of disputes over keys and costs.

Official forms and how to use them

Two useful official resources for Alberta renters are the general residential tenancies guidance and the dispute resolution application. If you cannot resolve a lock/key disagreement with your landlord, the province offers a dispute service and forms to request a hearing or mediation.

  • Application for Dispute Resolution (RTDRS): use this form to ask the Residential Tenancy Dispute Resolution Service to hear your case, for example if a landlord insists you must provide keys and you believe that creates a safety risk[2].
  • Residential Tenancies Act (legislation): consult the Act for rules about alterations, access, and landlord obligations; reference it when preparing evidence for a dispute[1].

Evidence that helps in disputes

  • Receipts from a licensed locksmith showing date and work done.
  • Photographs of new locks or damaged keys.
  • Copies of written notices or messages sent to the landlord about the lock change.

FAQ

Can I change the lock without telling my landlord?
Yes, in urgent safety situations a tenant can change a lock, but you should notify the landlord as soon as it is safe to do so and provide a key unless you have a documented safety plan.
Do I have to give the landlord a copy of the new key?
Generally landlords expect at least one copy for access and safety; if giving a key creates a safety risk, document the risk and seek advice from local services or the dispute resolution body.
What if my landlord insists I pay for rekeying I didn’t request?
Ask for an itemized receipt and the reason for the charge. If you disagree, use the RTDRS application process to resolve the dispute after trying to communicate in writing.
How do I file a formal complaint or dispute about locks or access?
You can file an application with the Residential Tenancy Dispute Resolution Service or follow the official guidance linked in the resources below to start a dispute.

  1. Check your lease for any lock or alteration clauses and note any required notice periods.
  2. Notify the landlord in writing explaining the safety reason or request permission for a non-urgent change and keep a copy of the message.
  3. Hire a licensed locksmith and keep the receipt and photos of the new lock or rekeyed cylinder.
  4. Provide a key to the landlord unless doing so risks your safety; if you withhold a key, document why and seek advice.
