Are Smart Locks Safe for Rental Properties?

What "safe" means for smart locks in rentals

Smart lock safety in rental properties refers to both physical security — whether the lock itself can be bypassed or broken — and access management security — whether the right people have access and the wrong people do not. This is a common source of confusion for landlords and tenants alike.

Quality smart locks from reputable manufacturers are generally as physically secure as traditional deadbolts. They are not meaningfully easier to pick, bump, or force than conventional locks. The meaningful security differences in rental contexts are almost always about digital access management, not physical vulnerability.

In other words, the question is not really "are smart locks safe?" — it is "are smart locks managed safely?" This article explains the risks, benefits, and responsibilities involved.

Physical security: How smart locks compare to traditional locks

Many people assume smart locks are less physically secure than traditional locks because they are "electronic" or "connected." This is largely a misconception.

Build quality and certification

Quality smart locks from brands like Yale, August, Schlage, and others typically carry the same security certifications as traditional deadbolts. They are tested for physical attack resistance, including drilling, picking, and forced entry.

The deadbolt mechanism

Most smart locks use the same deadbolt mechanism as traditional locks — they simply add an electronic method of turning it. The physical security of the bolt, strike plate, and door frame remains the primary barrier to forced entry.

Electronic attack surface

While smart locks do introduce electronic attack surfaces (such as Bluetooth or Wi-Fi vulnerabilities), practical exploitation of these vulnerabilities is rare compared to traditional methods of entry. Most burglaries target weak doors, poor installations, or unsecured windows — not smart lock hacking.

In summary: A quality smart lock, properly installed, is not meaningfully less secure than a quality traditional lock. The physical security difference is negligible.

Access management: Where smart lock security actually matters in rentals

The real security considerations for smart locks in rental properties are not about physical break-ins — they are about who has access and when.

Code management between tenancies

If access codes are not reset between tenants, previous occupants may retain the ability to enter the property. This is arguably a greater security risk than any physical vulnerability — and it is entirely preventable with proper procedures.

Code sharing during tenancy

Tenants may share access codes with friends, partners, or service providers. While this is also true of physical keys, smart locks make it easier to share access digitally — and harder to track who has codes.

Lost or compromised credentials

If a landlord loses access to the lock's account, or if the account is compromised, it may be difficult to manage the lock properly. Secure credential storage is essential.

Remote access considerations

Some smart locks allow remote unlocking via the internet. If enabled, this introduces additional security considerations — but also provides convenience for remote access management. Landlords should understand what remote capabilities their lock has and how to control them.

Benefits of smart locks in rental properties

Despite the access management responsibilities, smart locks offer genuine benefits in rental contexts.

No key handover required

Tenants can be given access codes remotely, eliminating the need for physical key handovers. This is especially useful for self-check-in rentals, late arrivals, or properties where landlords live far away.

No lost key problems

Tenants cannot lose a code the way they can lose a physical key. If a code is compromised, it can be changed instantly without replacing hardware.

Temporary access for contractors

Smart locks allow landlords to create temporary codes for cleaners, maintenance workers, or delivery drivers that expire after a set time. This eliminates the need to be physically present for every access event.

Access logging

Many smart locks maintain logs of when they were locked and unlocked. This can be useful for resolving disputes, tracking maintenance visits, or simply monitoring property access.

Clean tenancy transitions

Changing access between tenants is instant and free. No locksmith visits, no key cutting, no physical handover logistics.

Risks and responsibilities landlords should understand

Smart locks are not set-and-forget technology. They require ongoing management.

Battery failure

Smart locks run on batteries. If batteries die and there is no backup access method, tenants can be locked out. Most smart locks provide low-battery warnings, but landlords should ensure tenants know how to replace batteries and that physical key backups exist.

Technology failure

Apps crash, Bluetooth connections drop, and firmware updates can cause problems. Physical key backup is not optional — it is essential.

Tenant unfamiliarity

Not all tenants are comfortable with smart technology. Clear instructions are necessary — and some tenants may prefer traditional keys entirely. Consider whether a smart lock is appropriate for your tenant demographic.

Account security

If the landlord's account is compromised, an attacker could potentially lock out tenants or grant unauthorized access. Use strong passwords, enable two-factor authentication where available, and store credentials securely.

Privacy considerations

Access logs can reveal when tenants come and go. While this is not necessarily a problem, landlords should be transparent about logging capabilities and use the data appropriately.

Best practices for safe smart lock use in rentals

To use smart locks safely in rental properties, follow these guidelines.

• Always maintain a physical key backup — Never rely solely on electronic access
• Reset codes between every tenancy — Make this a non-negotiable part of checkout
• Use landlord-owned accounts — Do not let tenants create the primary account
• Document all access codes and credentials — Store them securely and update records when codes change
• Provide clear tenant instructions — Explain how to use the lock, change batteries, and what to do if locked out
• Choose quality hardware — Use reputable brands with good security track records
• Enable notifications — Receive alerts for low battery, failed access attempts, or other events
• Test regularly — Verify the lock works correctly between tenancies

Summary

• Quality smart locks are physically as secure as traditional locks
• The real security questions in rentals are about access management, not physical vulnerability
• Benefits include remote access, no key handovers, and easy code changes between tenants
• Risks include battery failure, technology problems, and the need for proper code management
• Always maintain physical key backups and reset codes between tenancies
• Smart locks are safe when managed properly — the question is whether they are managed properly
