Smart locks are no longer just a high-tech novelty—they’ve quickly become one of the most requested upgrades we see across Perth homes, rentals, and short‑stay properties. One brand we’re regularly asked about is McGrath Locks.
So, are McGrath smart locks actually worth it? Which model should you choose? And are they suitable for Perth homes and doors?
In this guide, our local Perth locksmiths break down everything you need to know—from security and reliability to installation considerations—so you can make an informed decision before you buy.
Quick Links
What Are McGrath Smart Locks?
McGrath is an Australian brand offering a range of keyless and smart entry locks designed for residential and light commercial use. Their smart locks are popular because they balance modern features with straightforward operation—without requiring a complex smart‑home setup.
Depending on the model, McGrath smart locks can offer:
- PIN code access
- Fingerprint unlocking
- Smartphone app control (usually via the TTLock app)
- Physical key backup
- Temporary or time‑limited access codes
They’re commonly installed on:
- Front doors
- Rental properties
- Airbnb and short‑stay accommodation
- Home offices
- Granny flats and secondary dwellings
Are McGrath Smart Locks Secure?
When installed correctly, McGrath smart locks offer a high level of security comparable to quality mechanical locks.
Key security benefits include:
- No physical keys to lose or copy
- Encrypted app communication
- Auto‑locking features (never forget to lock the door again)
- Activity logs (on supported models)
However, like all smart locks, security depends heavily on correct installation and door condition. A poorly aligned or unsuitable door can compromise even the best smart lock.
Do McGrath Smart Locks Need Wi-Fi?
Most McGrath smart locks do not require Wi-Fi for everyday use.
- Offline: PIN codes and fingerprints work locally without the internet.
- Bluetooth: Commonly used for app access when you are near the door.
- Wi-Fi: Some features (like unlocking the door from work for a tradesperson) will require a separately sold Wi-Fi Gateway bridge.
This makes them a practical option for Perth homes without reliable Wi‑Fi extending to the front gate or door. The popular McGrath Albion digital lock, for example, functions perfectly as a standalone Bluetooth unit.
What Happens If the Battery Goes Flat?
This is one of the most common concerns we hear. McGrath smart locks are battery‑powered, but they have fail-safes:
- Low‑battery alerts: The lock and app will warn you weeks in advance.
- Emergency power: Most models have a USB port on the outside. If the battery dies, you can plug in a portable power bank to “jump-start” the screen and enter your code.
- Physical key: They come with a mechanical override key (hide this outside the home in a keysafe, just like a car spare key).
LSF Pro Tip: Battery changes are simple, but ignoring low‑battery warnings is the #1 cause of smart lock lockouts we attend.
Can McGrath Smart Locks Be Installed on Any Door?
Not every door is suitable for a smart lock straight out of the box. In Perth, we commonly see issues with:
- Older timber doors (swollen or warped)
- Aluminium and security screen doors (narrow frames)
- Weather‑affected door frames
In some cases, minor door modifications are required to ensure correct alignment. If the bolt rubs against the frame, the battery will drain faster and the motor may burn out.
Will It Survive the Perth Summer?
Another reason the LSF team really likes McGrath locks is their durability. Many cheap “online-only” smart locks suffer from screen delamination or plastic fatigue after just one Perth summer.
McGrath locks generally feature robust IP ratings (weather resistance) and quality finishes designed to withstand Australian UV levels. However, if your door faces direct afternoon sun or is within 5km of the coast, ask us about the best finish to choose to prevent tarnishing.
Are Smart Locks Allowed on Rental Properties in WA?
In most cases, yes—but approval from the property owner or manager is required.
Smart locks are increasingly popular in Perth rentals because they reduce key replacement costs and allow easy access management.
Note for Tenants: We recommend keeping the original handles and lock hardware in a safe place. You may be required to reinstall the original lock to “make good” the property at the end of your lease.
DIY vs Professional Smart Lock Installation
While many McGrath smart locks are marketed as DIY‑friendly, professional installation offers key advantages:
- Correct door assessment: We ensure the lock fits the pre-existing holes or modify them precisely.
- Precise alignment: Essential to prevent jamming and battery drain.
- Setup support: We help set up the app and access codes.
Here at Lock, Stock & Farrell we regularly attend smart lock callouts caused by DIY installation errors, particularly on older Perth homes where doors may have shifted over time.
Is a McGrath Smart Lock Right for Your Perth Home?
McGrath smart locks are a solid, Australian-supported option for many Perth households and short‑stay properties. However, the right model depends on your door type, usage needs, and budget.
If you’re unsure which McGrath smart lock is best for your property, speaking with a local locksmith before purchasing can save time, money, and frustration.
