Buying a smart lock isn't like buying a new kettle. Get it wrong and you're dealing with a locksmith, a frustrated family, or worse — a security vulnerability on your front door. The good news? The right questions separate a smart purchase from an expensive mistake. Here are the ten most critical ones.
1. Will it fit my door?
This is the first question most people forget to ask. Smart locks are designed for specific door types — mortice locks, euro cylinders, or multipoint locking systems. If you have a uPVC or composite door, your options narrow significantly. Always check compatibility before anything else.
2. What happens when the battery dies?
Every smart lock runs on batteries. The critical question is: can you still get in when they fail? Look for locks with a physical key override, an external battery terminal, or low-battery alerts well in advance.
3. Does it work without the internet?
Many smart locks rely on Wi-Fi or a hub. If your broadband goes down, can you still unlock your door? Bluetooth-based locks work locally without internet — an important consideration for reliability.
4. Who controls access — and how?
Can you grant temporary access to a cleaner, guest, or contractor? Can you revoke it instantly? Look for time-limited PIN codes, app-based access sharing, and a full access log so you always know who came and went.
5. Is it actually secure?
A smart lock should meet at least Sold Secure Silver or ideally Gold standard. Check for anti-pick, anti-drill, and anti-snap ratings. A lock that's smart but weak physically defeats the purpose entirely.
6. Which app does it use — and is it any good?
Your smart lock is only as good as its app. Check reviews, look for regular updates, and confirm it works on both iOS and Android. A poorly maintained app is a red flag for long-term reliability.
7. Does it integrate with my smart home?
If you use Alexa, Google Home, or Apple HomeKit, check compatibility before buying. Not all smart locks play nicely with all ecosystems — and retrofitting later is rarely straightforward.
8. Can I install it myself?
Some smart locks are genuinely DIY-friendly; others require a locksmith. Factor installation cost into your budget if you're not confident with tools, and check whether the manufacturer offers installation support.
9. What's the warranty and after-sales support like?
Smart home hardware can develop faults. A solid warranty (minimum 2 years) and responsive UK-based support matters — especially for something as critical as your front door.
10. Is this a long-term investment or a gimmick?
The best smart locks are built on established platforms (like TTLock or Z-Wave) with active developer communities. Avoid obscure brands with no update history — your lock needs to work in five years, not just five months.
