Changing Locks and Key Replacement Rules in Alberta

Changing the locks or replacing keys in a rental can protect your safety, but it raises legal and lease-based issues tenants should understand in Alberta. This guide explains when tenants can change locks, when landlord consent is needed, how to provide duplicate keys, and steps to follow if a landlord refuses or changes locks without permission. It also shows which official forms and the dispute process to use, with practical examples for renters dealing with safety concerns, lost keys, or privacy. Read the clear steps to document your actions, request permission, and, if necessary, apply to the province’s dispute service so you can protect your rights and avoid penalties.

What Alberta law says about locks and landlord entry

Alberta's Residential Tenancies Act sets rules about landlord entry, notice, and tenant obligations under a lease. Tenants are expected to allow reasonable access for repairs and inspections if proper notice is given, and landlords generally retain an interest in the rental property’s security systems.^[1] Changing locks without addressing those obligations can lead to disputes if the landlord can no longer access the unit for legitimate reasons, like emergency repairs or safety checks.

Can a tenant change the locks?

Short answer: often yes, but with conditions. Many leases include specific clauses about altering locks. If the lease forbids changing locks, the tenant should follow the lease terms or get written permission. When a tenant changes locks, they should normally provide a duplicate key to the landlord so the landlord can fulfill their legal obligations (for repairs, emergency entry, or inspections).

When to get landlord permission

• Ask in writing if your lease contains an alteration or modification clause.
• Provide a duplicate key immediately after changing locks so the landlord can access for emergencies or scheduled visits.
• Get confirmation by email or text that the landlord received the key and accepted the change.

When changing locks is allowed without permission

There are circumstances where safety concerns justify changing locks immediately, such as domestic violence, stalking, or an immediate security threat. In such cases, change the locks, notify the landlord promptly in writing, and explain the safety reason. If you are worried about retaliation, mention that in your message and keep records of any threats.

What if the landlord changes or withholds keys?

If a landlord changes locks and does not provide new keys, or refuses reasonable access to a tenant, the tenant should document the situation, keep copies of lease terms, and ask for immediate return of access. If the landlord still refuses, a tenant can apply to the province’s dispute resolution service to seek remedies, including orders to allow access or compensation.^[2]

Practical steps to take

• Document dates, times and communications about keys and locks.
• Send a clear written request for keys or permission to change locks and keep a copy.
• If unresolved, consider applying to the RTDRS for a hearing on the dispute.

Official forms you may need

Below are the most relevant official forms and how tenants typically use them in Alberta.

• RTDRS "Application to Resolve a Dispute" (RTDRS application): Use this form to start a dispute if a landlord refuses to provide keys, changes locks improperly, or violates entry rules. Example: after written requests fail, a tenant fills this application to ask for an order requiring the landlord to return access or compensate for locksmith costs.^[3]
• RTDRS "Response to Application": If a landlord opposes an application, they use this form to respond and provide their side before a hearing. Example: a landlord who changed locks will explain why and submit evidence supporting their action.

Tips for documenting and protecting your position

• Keep dated photos, locksmith receipts, and copies of all messages.
• Use a licensed locksmith and keep the invoice as evidence of necessity and expense.
• Note any safety incidents that prompted the lock change and, if possible, get third-party corroboration.
