Maintenance & Repairs Alberta 4 min read · published March 09, 2026 Flag of Alberta

Changing the locks can feel like a worry for renters in Alberta - you want safety without breaking rules. This guide explains when a tenant may change or rekey locks, what landlords are allowed to do about keys and entry, and how to handle disputes or urgent repairs. It covers the province's official tribunal, common forms, and practical steps to document changes and communicate with your landlord. Whether you are protecting yourself after a breakup, replacing a worn lock, or responding to a safety concern, the information here helps you act within Alberta law and preserve your rights as a tenant.

Rights and rules for locks in Alberta

Tenants in Alberta generally have the right to feel secure in their homes, but that right exists alongside the landlord's right to access the unit under specific conditions. If you change a lock, consider whether the lease or a written agreement says anything about keys or lock changes. In Alberta, the Residential Tenancies Act sets the legal framework for landlord and tenant obligations and is the starting point for questions about locks and keys.[1]

Keep a written record of any permission or refusal from your landlord about changing locks.

When tenants can change locks

Common situations where tenants may consider changing locks include safety concerns, a lost key, or after a domestic dispute. Before doing so, check the lease and try to get written permission. If you must change a lock immediately for safety, document why it was necessary and notify the landlord promptly.

  • Check your lease for any clause about keys, locks, or landlord access.
  • Contact the landlord in writing to request permission or explain the reason for an emergency change.
  • Provide a copy of the new key to the landlord unless there is a valid safety reason not to.
  • Keep dated photos, receipts, and messages as evidence of the change and communication.
If you permanently deny the landlord a working key without a legal reason, you may risk breaching the lease.

Landlord access and keys

Landlords retain the right to enter for allowed reasons, such as repairs, inspections, or to show the unit with proper notice. If you change a lock and do not provide access, a landlord may take steps to regain access, but they must follow legal procedures rather than forcing entry unlawfully. If access becomes disputed, you can apply to Alberta's dispute resolution service for help.[2]

Clear, polite written communication often prevents escalation to formal disputes.

Practical steps before changing a lock

Follow these steps to balance safety and legality:

  • Read your lease to see if locks or spare keys are addressed.
  • Request permission from the landlord and keep the response in writing.
  • If an emergency requires an immediate lock change, notify the landlord as soon as possible and explain why.
  • Document the new lock model, invoice, and date of change.
  • Use a qualified locksmith and retain the receipt to show the change was professional.
Documentation and timely notice are the best protection in a landlord-tenant disagreement.

Resolving disputes and formal remedies

If you and your landlord cannot agree, Alberta offers a formal dispute process through the provincial dispute resolution service. That tribunal handles issues such as unlawful entry, refusal to accept a key, or contested lock changes. The tribunal's application forms and guidance explain how to present evidence and request remedies.[2]

Keep copies of every message, photo, and receipt in a single folder for any dispute.

When to apply for a hearing

  • You have been denied essential access or the landlord is entering without notice.
  • You changed a lock for safety and the landlord is threatening eviction or penalties.
  • There is conflicting written evidence about who provided keys or permissions.
