The Short Answer: Yes, Quality Smart Locks Are Safe
Modern smart locks from reputable brands (Yale, Aqara, ULTRALOQ) are at least as secure as traditional deadbolts — and in many ways, more secure. Here's why, and what to watch out for.
Concern #1: Can Smart Locks Be Hacked?
The reality: Hacking a quality smart lock is extremely difficult and impractical for burglars.
Smart locks use AES-128 or AES-256 encryption — the same standard used by banks and military. Cracking this encryption with current technology would take millions of years.
Burglars overwhelmingly prefer physical methods — kicking doors, breaking windows, or simply trying unlocked doors. No Australian police report has documented a burglary where a smart lock was electronically hacked.
What to look for: - BHMA Grade 1 or Grade 2 certification - AES-128 encryption minimum - Auto-lock feature (the #1 security benefit — your door always locks behind you) - Two-factor authentication option
Concern #2: What If the Battery Dies?
Every smart lock on our recommended list includes a physical key backup. You cannot be permanently locked out.
Additionally: - Smart locks give weeks of low-battery warnings via push notifications - Most run on standard AA batteries lasting 6-12 months - The Eufy Smart Lock Touch has an emergency USB-C port — connect a portable charger to power it instantly - The ULTRALOQ Bolt SE also provides emergency USB power
Our advice: Change batteries proactively when you get the first low-battery alert. Keep a spare key hidden as a last resort.
Concern #3: What About Australian Home Insurance?
This is a common worry, but generally unfounded:
- Most Australian home insurers don't distinguish between traditional and smart locks as long as the door was locked at the time of a break-in
- Smart locks often improve your security posture because auto-lock means your door is always locked
- Some insurers may even offer discounts for smart security systems
Our advice: Check your specific policy and mention your smart lock to your insurer. Get their confirmation in writing if you want peace of mind.
Concern #4: What About Power Outages?
Smart locks run on their own batteries, completely independent of your home's electricity. A power outage doesn't affect your lock at all.
However: - Wi-Fi features (remote locking) will stop during an outage since your router needs power - Physical keypad, fingerprint, and physical key access all work normally - Bluetooth access works from close range even without Wi-Fi
Concern #5: Privacy — Who Has Access?
Smart locks give you more control over access, not less:
- Access logs show exactly who unlocked the door and when
- Temporary codes let you give tradespeople time-limited access
- Revoke access instantly — no need to change locks if a housemate moves out
- No physical keys to lose or copy without your knowledge
With a traditional lock, anyone who copies your key has permanent, untrackable access. Smart locks solve this completely.
The Real Security Benefits
Smart locks actually improve your security:
1. Auto-lock — Door always locks behind you (most Australians leave doors unlocked accidentally) 2. Access logs — Know exactly who entered and when 3. Remote monitoring — Check lock status from anywhere 4. No key hiding — No spare keys under doormats for burglars to find 5. Instant access revocation — Change codes in seconds, no locksmith needed

Bottom Line
Smart locks from reputable brands are safe, practical, and in many ways more secure than traditional deadbolts. The convenience of auto-locking alone makes your home more secure than a traditional lock that you might forget to lock. Start with a quality brand, keep batteries fresh, and keep your physical backup key somewhere safe.
