Locksure cannot unlock your door remotely — making it more secure than smart locks.
Why two monitors?

Customer Reviews

“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.”

“Very easy to set up and install too. Super simple in fact. Well packaged and everything is clearly labelled. Works well. 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. They were really happy with this and gave both them and me confidence that the house was secure.”
