What Our Customers Say
The visual flash of the LEDs alone when I lock the door really stick in my memory. Locksure has been on my door for over six months now and I want to keep it!
I was skeptical at first because I don't have the problem of forgetting to lock my doors. Well I didn't think I did until I realised how long the door is left open by my kids! The history feature really help me get to the truth of when the kids came in and out of the house, even when I am in the office!
The kids can make getting into the car a stressful experience sometimes. Then I get onto the A1 and think "have I locked the door?" Now I just stop and look at the app and I know for sure! Thanks Locksure!
We have a three story house and, just before bed, I get paranoid if I remembered to lock the door and end up going all the way downstairs to check. No more with Locksure, I just check the app and have peace of mind.
Very easy to set up and install too. Super simple in fact.
Well packaged and everything is clearly labelled.
Works well. Seems like overkill but if you require such a device (I don’t so it’s more of a gimmick for me) then this is certainly a good place to look. Well made, wonderfully packaged and the company seems to offer good after sales support too. Would recommend.
I got this as I wanted confidence that my parents were locking the door each night and without feeling like they were too intruded upon. They were really happy with this and gave both them and me confidence that the house was secure. I can think of a number of different applications but for me it was perfect to ensure that my parents were secure at home.
I rent a flat and can’t change the lock, so this was the perfect solution. It sits neatly over the existing key turn and connects easily to the hub. I love that I can see if the door is locked from anywhere using the app.
No security risks like remote unlocking – just simple status updates. A great smart home addition that doesn’t mess with your actual door hardware. Would definitely recommend to anyone with kids or elderly relatives.

Questions, answered
Will it fit my door?
If you have a thumb-turn or Euro cylinder key-turn, you're good.
Unsure? Tap the monitor type for your door and check the fit photo.
Do I need to change my lock?
No. Locksure is a retrofit sensor — it reads the lock position; it
doesn’t operate the lock.
Does it work if my Wi-Fi goes down?
The hub keeps state; cloud/app updates when your hub is back online.
What’s your returns policy?
30-day free returns and a 1-year warranty from our UK team.
What's in the pipeline?
We are working away in making locksure better for you. Here are features being developed this year:

A Family Driven Solution
Born out of a real-life necessity, our journey began when we recognised the vulnerability of homes, particularly those of elderly residents, to opportunistic thieves. Our founder's own father-in-law faced the same peril, often forgetting to lock his front door in a neighbourhood targeted by such criminals.
Initially, the idea of investing in a smart lock seemed plausible, but the cost, including installation and an additional hub, made it an impractical choice to simply know if the door is locked. Moreover, remote control over the door's locking mechanism seemed less secure. Determined to find a more effective and affordable solution, we crafted a prototype that not only addresses the issue but also prioritises user independence.
Our Locksure Door Lock Monitoring prototype is a game-changer. Instead of relying on an expensive and less secure smart lock, our door lock sensor system sends instant notifications to a user-friendly app whenever the door is left unlocked. This not only serves as a reminder but also allows for quick and simple intervention through a phone call. Our founder's father-in-law greatly appreciates the independence this solution provides, giving him control without sacrificing security.
After successfully implementing Locksure Door Lock Monitor in our own home, the response from neighbours was really positive. Many expressed interest in how our prototype could help them remember to lock their doors as well. After getting enough made to startup Locksure, we tested the device with our Friendly Testers and are now ready to offer Locksure to the UK and soon the rest of Europe.
Join the movement towards enhanced home security with Locksure – the intelligent, affordable, and user-friendly solution that puts you in control. Don't compromise on safety; invest in peace of mind today.
