Fantastic Smart Lock — Secure, Convenient & Easy to Use!
Color: Pitch black
I’m absolutely impressed with this Smart Lock 4-in-1 Keyless Entry Door Lock! Installation was straightforward — the instructions were clear, and it fit perfectly on my front door without any hassle. Within minutes, I had both the keypad and Bluetooth app control set up and working seamlessly. The digital keypad is super responsive, and I love that I can create multiple access codes for family members, guests, or service providers. The Bluetooth connectivity through the app is reliable, and I’ve had zero issues locking/unlocking from my phone — even when I’m away from home. What really sets this lock apart is its versatility. The 4-in-1 keyless entry options mean I’m not dependent on a physical key anymore, but I still have the option if I need it. The deadbolt feels solid and secure, and the overall build quality gives me peace of mind. Overall, this smart lock has added both security and convenience to my front door. It’s a great upgrade from a traditional deadbolt and I highly recommend it to anyone wanting a smarter home entry solution! ... show more

Elegant and safe
This digital lock exceeded my expectations. It has a very elegant design that adds a modern touch to any door, and it feels very secure from the very first use. Installation was simple, and you don’t need to be an expert to set it up perfectly. I love how practical it is, with a quick response and reliable performance. It truly gives peace of mind when leaving or arriving home. Definitely a great investment for anyone looking for convenience, style, and protection in one product. ... show more

The app does not work with this
Color: Pitch black
Do not buy this item it does not work with the app and you cannot find any directions or support to help you get it. Configured works fine manually but not with the smart app. I even have the hook that goes with it and it does not work. You cannot get support for it.

Many options to unlock
The lock works and I love that there are so many ways to unlock the door. We have it on our lake cottage and gave the key cards to close friends in case they need in. We kept the keys in case it doesn't work right at some point. I love being able to lock the door from bed or unlock when a guest comes without having to stop what I'm doing and go to the door. I did think I would be able to unlock it from home and set a one time code from home but you have to be there for it to connect to Bluetooth but I can always send my code and change it when im back if need be. I think having the option to connect via wifi would be better but this will do for now. It looks sleek and was easy to install. I did need to go on the app and switch the door so that it said unlock and lock for the appropriate action but once I figured that out it was no big deal. ... show more

Secure and affordable
Color: Pitch black
The MOUSETRO Smart Door Lock is a game-changer for home security and convenience. It’s incredibly easy to install and even easier to use. I love that it offers multiple unlocking options — passcode, app, IC key fob, and a traditional mechanical key — which makes it perfect for families with elderly members or kids who might forget passwords. The design feels sturdy and modern, and the app integration works flawlessly for remote access and monitoring. No more worrying about being locked out or losing keys — this smart lock gives real peace of mind. Highly recommend it for anyone looking to upgrade their home security system! ... show more

Smart door lock
I’ve just installed this door lock on my front door and it works great. The lock is powered by replaceable batteries, which makes maintenance very easy. Installation was straightforward in my case I only needed to slightly enlarge the hole with a drill and it fit perfectly. Overall, I think it’s a good price for these features. ... show more

7/10 stars.
Color: Pitch black
The installation wasn’t too hard. It can be kind of annoying sometimes because the numbers are very sensitive so if you’re not right on the number it won’t unlock. But it has been very easy to use. Connectivity is good. Quality I would say is pretty good. Weight isn’t heavy at all.

No wifi no internet
I think this was very misleading when it mentions you can have remote access to the product. Like many, I was hoping to connwct this device over wifi not Bluetooth. Defeats the whole purpose for the remote feature if I have to be a couple of feet away.
