Smart locks have been around for years now, but I still get asked the same question every few weeks: "Are they actually any good, or am I just asking to be locked out of my own house?"
It's a fair question. The early models earned a bit of a reputation - flat batteries at the worst possible moment, dodgy apps that needed an update before you could turn the handle, and the occasional security researcher demonstrating how to pop one open with a magnet and a YouTube tutorial. Most of that is behind us now, but the market has also got noisier. Walk into any DIY shop in Reading or Aylesbury and you'll find a wall of options, half of which I genuinely wouldn't fit to a shed.
Here's what I'd actually install on my own front door in 2026, and why.
Start with the door, not the lock
Before anything else: a smart lock is only as secure as the door it's bolted to. I've been called out to homes across Berkshire where someone has spent £300 on a fancy lock fitted to a 30-year-old uPVC door with a worn-out multipoint mechanism. The lock works perfectly. The door still pops open if you lean on it the wrong way.
If your door frame is split, your hinges are loose, or your existing euro cylinder is the cheap brass thing the builder fitted in 2003, sort that first. A decent anti-snap cylinder and a properly fitted strike plate will do more for your security than any app ever will.
What "smart" should actually mean
For me, a smart lock earns its place if it does three things well:
- It still works as a normal lock. Key on the outside, thumb-turn on the inside, no exceptions. If the batteries die at 11pm in February, you should be able to use a key like any other Tuesday.
- It doesn't need the cloud to open the door. Bluetooth or a local Wi-Fi connection should be enough for everyday use. Cloud features are fine for remote access, but if your internet drops, your front door shouldn't.
- It logs who came and went. Codes per family member, timestamps, the lot. This is the bit most people don't realise they'll love until they have it.
The kit I'd actually fit
I won't turn this into a shopping list, but a few patterns are worth mentioning. Retrofit locks that sit on the inside of your existing euro cylinder - the ones that grab your existing key and turn it for you - are usually the best starting point for British doors. They're tenant-friendly, they don't require any drilling, and if you ever decide smart locks aren't for you, you unscrew them and you're back to square one.
For new builds or full replacements, I prefer a proper European-standard motorised cylinder paired with a separate keypad outside. The keypad takes the wear and tear, the cylinder stays protected behind the door, and you've got a backup key slot that genuinely works.
What I avoid: locks that only open via app, anything with a fingerprint reader as the sole entry method (they fail in our climate more than the marketing suggests), and any brand I've never heard of selling on a marketplace for £40. If it goes wrong in two years, there'll be no firmware updates and no spare parts.
The features that have actually changed my customers' lives
The cleaner doesn't need a hidden key under the plant pot anymore. The dog walker has a code that only works between 11am and 1pm on weekdays. When the kids get home from school in Marlow or Maidenhead, you get a quiet notification on your phone - no panicked phone call, no checking the doorbell camera every ten minutes. When you're on holiday in Cornwall and your neighbour pops in to water the plants, you can give them a one-time code that expires the day you fly home.
None of this is revolutionary, but it's the sort of thing that quietly removes a dozen small frictions from a week.
A word on integration
If you've already got smart home kit - Hue lights, a thermostat, cameras - pick a lock that plays nicely with the same ecosystem. Matter support has finally made this easier than it used to be, but it's still worth checking before you buy rather than after. The best smart home is the one where everything talks to everything else without three different apps open at once.
The honest summary
A good smart lock, properly fitted to a sound door, is one of the genuinely useful upgrades you can make to a home. A bad one, fitted to a tired door, is an expensive way to pretend you're more secure than you are.
