If you’re running an Airbnb or short-stay property in Australia, one of the most common questions we hear is:

“Do I need WiFi for a smart lock to work?”

The short answer is: No — but automation depends on how your system is set up.

In this guide, we’ll explain:

• How smart locks work without WiFi
• What automation actually requires internet
• Igloohome vs TTLock (McGrath) differences
• Which setup suits single-property hosts vs multi-property operators

Airbnb Smart Lock Integration in Australia – What You Need to Know

Many hosts assume smart locks connect directly to Airbnb.

In Australia, Airbnb’s native smart lock integration (where Airbnb generates and pushes codes directly to the lock) is not widely available.

Instead, most systems work in one of two ways:

• The smart lock app reads your Airbnb bookings and generates codes automatically.
• A third-party Property Management System (PMS) creates and manages codes.

Do Airbnb Smart Locks Work Without WiFi?

Yes — many modern smart locks can generate time-based access codes that work without WiFi at the lock.

These codes are calculated using the lock’s internal clock, allowing guests to enter during their booking window even without an internet connection.

However, there is a difference between:

• A lock working without WiFi
• Full automation and remote management without WiFi

Igloohome for Airbnb Without WiFi

Igloohome locks can generate time-based PINs that work completely offline.

With Airbnb Connect enabled, the Igloohome app can:

• Read confirmed Airbnb bookings (other smartlocks cannot do this without WiFi)
• Automatically generate a time-limited PIN
• Send the PIN to the guest

The lock itself does not need WiFi for that code to function.

For single-property hosts wanting simple automation without additional hardware, this can be an excellent solution.

TTLock / McGrath Smart Locks Without WiFi

McGrath smart locks operate on the TTLock platform and can generate time-based offline PINs.

These codes work without WiFi at the property.

Just like Igloohome in offline mode, remote management features are limited without a gateway.

Using a Smart Lock with WiFi and a Gateway (Best for Multi-Property Hosts)

When you add reliable WiFi and a gateway (bridge), smart locks become far more powerful.

• Automatic PIN creation via PMS or other management software
• Instant code revocation
• Real-time access logs
• Cleaner attendance tracking
• Remote battery monitoring
• Scalable multi-property management

Smart Locks for Australian Doors – Why Compatibility Matters

Australian doors commonly use:

• 60mm / 70mm backsets
• Mortice locks
• Narrow aluminium doors
• Screen doors
• Fire-rated apartment doors

McGrath locks are designed around Australian door standards and retrofit requirements, offering broader compatibility across typical residential doors.

Simple Option for Occasional Hosts – Igloohome Keybox 3

Not every Airbnb host wants to replace their door hardware.

The Igloohome Keybox 3 allows you to securely store a physical key, generate temporary access codes, and operate without WiFi.

For occasional hosts or holiday homes, this is often the simplest and lowest-maintenance solution.

Which Airbnb Smart Lock Setup Is Right for You?

Airbnb + Igloohome (Simple & No-WiFi Friendly)

If you’re a single-property host (or you just want minimal fuss), Igloohome smart locks or the Keybox 3 can be a great fit — especially when WiFi isn’t available.

Airbnb + McGrath/TTLock (Best for Scalable, Managed Setups)

If you manage multiple properties (or already use a PMS/channel manager), McGrath/TTLock with a gateway can unlock professional management tools like automation, cleaner access tracking, and access logs.
