Smart Access for Short Stays, Holiday Homes & Airbnb Properties

The Mornington Peninsula is one of Victoria's most popular holiday destinations — and with that comes a high concentration of Airbnb properties, short-stay rentals and holiday homes that need reliable, flexible access solutions.

At Lockmart, we work with Airbnb hosts, holiday home owners and property managers right across the Peninsula — from Frankston and Mount Martha through to Rosebud, Rye, Sorrento and Portsea — as well as across Melbourne's Bayside, Casey and south-east suburbs.

Whether you're managing one property or a portfolio of short stays, we'll help you find the right solution — and make sure it works properly from day one.

The Problem With Traditional Keys for Short Stays

Key handovers are one of the biggest headaches in short-stay property management. Guests arrive at different times, check-outs get delayed, keys get lost — and every time a guest leaves with a copy you don't know about, your property's security is compromised.

There's a better way.

Digital Locks — The Most Popular Solution for Airbnb Hosts

A digital door lock eliminates the key handover entirely. Guests receive a unique PIN code before they arrive and check themselves in — no waiting around, no lockboxes, no drama.

McGrath digital locks are our most recommended solution for short-stay and holiday properties. They're robust, well-suited to coastal and Australian conditions, and integrate directly with Airbnb and other booking platforms — meaning guest access codes can be automatically generated and delivered upon booking confirmation, with zero manual setup required between bookings.

Schlage Encode is another strong option — with built-in WiFi, it connects directly to your home network without needing a separate hub or bridge, making remote management simple and reliable from anywhere in the world.

Other quality digital lock brands we supply and install include Borg, Gainsborough and Yale, covering a wide range of door types, budgets and property styles.

What We Do Beyond Just Installation

Lockmart doesn't just fit the lock and leave. Our team will:

• Walk you through the app setup and show you how to manage codes, users and access schedules
• Set up the lock on our own device first if needed, then transfer full ownership to you — so everything is configured and working correctly before we hand it over
• Show you how to create temporary codes for guests, cleaners and tradespeople
• Ensure you're confident managing the system independently going forward

This is the difference between a supplier and a locksmith who actually understands what you need.

Restricted Key Systems - Extra Security, or a Standalone Alternative

Not every door is suited to a digital lock, and some hosts prefer the simplicity and reliability of a physical key, or want to combine both for maximum security.

Lockmart's restricted key systems are a powerful option for short-stay properties. Unlike standard keys, restricted keys cannot be copied at a hardware store or key kiosk. Duplication requires formal authorisation from Lockmart, and that authorisation stays with you as the property owner.

This means even if a guest leaves with a key, it's worthless without your permission. No security risk, no re-keying required.

Used alongside a digital lock, a restricted key cylinder gives you a secure physical backup - ideal for maintenance access, owner visits, or as a failsafe if a guest has trouble with the digital system.

Used on their own, restricted keys offer a step up in security from standard locks without the need for any app or technology, a great fit for older properties, heritage doors, or hosts who prefer a traditional setup.
