How to Secure Your Home with Smart Locks
- •Smart locks offer keyless convenience without sacrificing security.
- •Choosing the right lock grade matters more than most homeowners realise.
- •Professional installation prevents the most common vulnerabilities.
- •Regular maintenance keeps your locks performing reliably long-term.
If you’ve ever stood at your front door fumbling for keys in the dark, you already know the frustration. Smart locks solve that problem — but only if you choose and install them correctly. Get it wrong, and you may trade one problem for a much bigger one.
What Makes a Smart Lock Actually Secure?
Not every smart lock on the shelf deserves to protect your home.
A smart lock is only as strong as its physical deadbolt mechanism. Connectivity features like Bluetooth or Wi-Fi are convenient extras — they don’t add structural strength to the lock body itself.
Look for locks with a solid brass or steel core and a robust strike plate. A lock with impressive app features but a weak cylinder can be bypassed in seconds by someone who knows what they’re doing.
The door frame is often the weakest point — not the lock itself. Reinforce your strike plate with 3-inch screws that anchor into the wall stud, not just the door frame timber.
Step 1: Choose the Right Lock Grade for Your Door
Matching lock grade to your door type saves you money and frustration.
Residential locks are typically graded by security level. A front entry door facing the street warrants a higher-grade deadbolt than an internal laundry door. Don’t over-invest where it isn’t needed — and don’t cut corners where it is.
If you’re unsure which grade suits your situation, a quick professional assessment of your current locks can identify gaps before they become a problem.
Step 2: How Should You Handle Installation?
DIY installation is tempting — here's when it becomes a liability.
Many smart locks are marketed as DIY-friendly, and for a straightforward door with a standard bore hole, that’s often true. But misaligned deadbolts or incorrect backset measurements can leave your door impossible to lock properly.
If your door has a non-standard thickness, a double-rebate frame, or an older mortice lock cutout, professional installation is the smarter call. A licensed locksmith ensures the lock seats correctly and the mechanism operates smoothly under load.
Always test your new lock with the door open before closing it for the first time. A lock that binds or sticks under door pressure can leave you locked out on day one.
Step 3: What Ongoing Maintenance Do Smart Locks Need?
A five-minute check twice a year keeps your lock reliable year-round.
Smart locks have both mechanical and electronic components, so maintenance covers two areas. On the mechanical side, lubricate the bolt mechanism every six months with a dry graphite or PTFE spray — avoid oil-based lubricants that attract grime.
On the electronic side, keep firmware updated and replace batteries before the low-battery warning triggers. Most smart locks give you two to four weeks of warning — don’t ignore it.
- •Lubricate the bolt every six months with dry PTFE or graphite spray.
- •Replace batteries at the first low-battery alert — don't wait.
- •Check the strike plate alignment after any significant weather changes.
- •Review and update access codes or user permissions every few months.
Smart Lock Questions Perth Homeowners Ask Most
Straight answers to the questions that come up on every job.
Can a Smart Lock Be Hacked Remotely?
Most reputable smart locks use encrypted communication protocols that make remote hacking extremely difficult in practice. The more realistic risk is a weak PIN code or a shared access credential that isn’t revoked when it should be. Strong, unique codes and regular permission audits address the vast majority of real-world vulnerabilities.
What Happens to a Smart Lock During a Power Outage?
Most smart locks run on battery power independently of your home’s mains electricity, so a power outage has no direct impact. The exception is locks that rely on a Wi-Fi hub for remote access — you may lose app control, but the lock itself still operates locally via keypad or physical key.
Is a Smart Lock Suitable for a Rental Property?
Yes — and smart locks are particularly practical for rentals because you can issue and revoke access codes between tenants without a physical rekeying job. Always check your state tenancy regulations and confirm with your property manager before installing, as some agreements require landlord consent for lock changes.
How Do I Know If My Current Door Is Compatible?
Most smart locks are designed to fit standard Australian door preparations, but variables like door thickness, backset distance, and existing lock type all affect compatibility. The quickest way to confirm is to call a locksmith for a five-minute assessment — it saves you buying hardware that won’t fit.
