Property Management Tips
Smart locks have become popular with tenants who want convenient access to their homes. The problem is that many tenants install these devices without informing the landlord. What looks like a small upgrade creates serious security, legal, and operational issues for rental properties in Ontario.
Under Ontario’s Residential Tenancies Act, tenants cannot change the locking system without providing the landlord with a working key or code. They also cannot alter access in a way that prevents the landlord from entering for legal reasons such as maintenance, inspections, or emergencies.
When smart locks are installed without permission, landlords lose the ability to access the unit properly. This affects safety, compliance, and turnover timelines.
Why Smart Lock Installations Are Becoming More Common
Many tenants buy inexpensive smart locks from hardware stores or online marketplaces. These devices promise convenience, app-based access, and easier guest entry. To the tenant, it feels like a harmless upgrade.
The issue is that smart locks function differently from traditional locks. They often require unique apps, custom pairing, Wi-Fi connections, and firmware updates. Without the landlord’s knowledge or access credentials, the property becomes difficult to manage.
How Unauthorized Smart Locks Affect Landlord Access
Ontario landlords must be able to access a rental unit for maintenance, inspection, and emergency situations. When a smart lock is installed without permission, several problems occur.
No Physical Key: Smart locks often remove the need for a physical key. If the tenant leaves or becomes unreachable, the landlord cannot enter.
Unreliable Access Codes: Tenants can change codes at any time. A landlord may be locked out without warning.
Battery or Wi-Fi Failure: When batteries die or internet connectivity fails, the lock stops working. If this happens during an emergency, the landlord cannot enter until the device is bypassed or removed.
Compatibility Issues: Some locks are not CSA-approved or compatible with building fire safety systems. This creates liability risk for landlords and building management.
How Unauthorized Locks Slow Down Turnover
Turnover depends on predictable access. When a tenant has installed a smart lock without permission, move-out day becomes complicated.
- Cleaning teams cannot enter.
- Inspections are delayed.
- Photos cannot be taken.
- Maintenance cannot start.
- Lock replacements take longer.
A single unauthorized smart lock can add several days to a turnover timeline. For landlords, that delay translates into lost rental income.
Security Risks for the Building
Unauthorized smart locks affect more than one unit. They create broader risks.
Multiple Active Codes: Some devices allow unlimited guest codes. Landlords cannot verify who has access.
Unsecured Apps: If a tenant uses a weak password, guest access may be compromised.
Unapproved Hardware: Cheaper smart locks can be easily removed, hacked, or bypassed.
In multi-unit buildings, these risks extend to neighbours and common areas.
What Ontario Law Says About Locks
The Residential Tenancies Act states that tenants cannot change or alter the locking system without providing the landlord with a key or equivalent access device.
If a tenant installs a smart lock without permission and does not provide working access, it becomes a violation of the Act.
Landlords are permitted to replace or remove unauthorized locks as long as access is restored and notice requirements are followed. In emergencies, landlords may enter without notice, but unauthorized smart locks often make this impossible.
How Royal York Property Management Prevents Access Issues
Royal York Property Management handles access and security through organized systems that reduce risks created by unauthorized lock changes.
Documented Move-In Conditions: Any existing lock is photographed and documented so that unauthorized changes are easy to identify.
Clear Lease Terms: Lease agreements outline that locks cannot be altered without written permission.
Twenty-Four-Hour Support: If a tenant changes a lock or denies access, the issue is escalated immediately.
Coordinated Lock Changes: Locks are replaced at turnover to ensure future access and security.
Centralized Key Management: Keys and access codes are stored safely across more than twenty offices in Ontario, which prevents unauthorized duplication.
These systems reduce safety risks and avoid delays at the end of a tenancy.
What Ontario Landlords Should Do If They Discover an Unauthorized Smart Lock
If a landlord finds a smart lock installed without permission, they should take a structured approach.
- Request access codes or keys in writing.
- Document the issue with photos.
- Review the lease to confirm lock policies.
- Inform the tenant of their obligations under the Residential Tenancies Act.
- Schedule a lock replacement at the earliest legal opportunity.
- Ensure building management is aware if it affects common areas.
Documentation and timely action prevent disputes and reduce risk.
Final Thoughts
Unauthorized smart locks create far more problems than tenants realize. They affect legal access, emergency response, turnover timelines, screening quality, and building security. In Ontario’s rental market, where structure and consistency matter, landlords cannot afford uncertain access to their own properties.
Clear policies, proper documentation, and professional management systems protect landlords from the risks associated with unauthorized lock changes.
