Decent Smart Lock
Color: Black
Set name: Lever Handle Set
To get everything working, you’ll need to download the app. It’s easy to use and lets you control the lock from your phone, which is a nice bonus. This door lock comes with a handle, which is a nice extra, and the quality is really good for what you pay. Installing it was simple, and I was able to do it by myself without any trouble. I really like that there are several ways to unlock it. You can use a regular key, a code you set, the little key tags that come with it (you just tap them on the lock), or even your fingerprint. Having all these options makes it super convenient. There’s also an auto‑lock feature you can turn on if you want. It locks the door after a set amount of time, and you can change the timer in the app. Just remember that if the door is open when it tries to auto‑lock, you’ll have to unlock it again before closing the door. You can also turn auto‑lock off completely. What I didn't like was the fingerprint scanner—it can be a little picky. I had to try several times to get it to work and switched with the thumb that works the best. Also, the fingerprint failed too many times, the lock goes into a security mode, sets off a siren, and won’t work again until you unlock it through the app. Battery life is unknown as it's only been awhile but I have another smart lock where batteries are drained fast and I have to keep lithium batteries on deck to exchange every 3 months. So if you put in a high use area it would not last for 12 months.

From Basic Deadbolt to Smart, Fingerprint‑Powered Access
Color: Silver
Set name: Deadbolt
The DESLOC Smart Door Lock B200 is a great upgrade from a traditional key‑based lock, especially if you’re tired of carrying keys or dealing with misplaced ones. I installed it on the entry door to my garage, and it’s been a solid improvement in both convenience and security. Setup was straightforward. I easily added individual fingerprints for my kids and wife, plus unique access codes for each of them. The Bluetooth app control works reliably, letting me manage codes and check access without needing Wi‑Fi. It’s a well‑designed smart lock that fits nicely into a modern home setup. One of the best features is the ability to create pre‑programmed guest codes, which makes it perfect for visitors, babysitters, or temporary access without handing out physical keys. The overall build feels sturdy, and the design is clean and practical. Considering the features—fingerprint unlock, keypad, app control, and keyless entry—the price is very fair. If you’re looking for a smart deadbolt that’s easy to use and a strong replacement for a standard lock, the DESLOC B200 is a great choice.

Excellent Smart Lock and a Great Addition to My Home
Color: Black
Set name: Lever Handle Set
I purchased this smart lock because I already have three smart locks in my house on my front door, garage, and basement, but I had never replaced the lock on my back door. When I went to purchase another one to match the locks I already had, the model I wanted was no longer available, so I decided to try a different brand. I’m extremely pleased that I did. The installation was very easy, and everything I needed to install the lock was included in the box. Once installed, it feels very solid and well made. The overall quality is just as good as the other smart locks I already have, and I have no complaints about the construction. Programming and setting it up was also very straightforward. I really like having the ability to control the lock through the app on my phone. There are several ways to unlock it, including entering a passcode, using my fingerprint, or using my phone, which makes it incredibly convenient. This is especially useful for me because I don’t always remember to take my keys with me. I’ve actually locked my keys inside the house before, and having a smart lock on the back door gives me another way to get back inside without having to find someone with a spare key. Being able to use my fingerprint, phone, or a code makes this an extremely valuable addition to my home. Overall, I am extremely happy with this smart lock. It was easy to install, easy to program, feels very high quality, and gives me multiple convenient ways to access my home. I wasn’t able to get the exact model I originally wanted, but after using this one, I’m glad I went with it. I would definitely recommend it to anyone looking for a quality smart lock with multiple entry options.

Great lock a few downsides
Color: Black
Set name: Lever Handle Set
This door lock came with a handle included, which is a great bonus, and overall the quality is very good for the price. Installation was straightforward and easy to do on my own. One thing I really like is the variety of ways you can unlock the door. You can use physical keys, a custom code, the included key tags (just tap them on the lock), or even your fingerprint. Having multiple options makes it very convenient for different situations. The lock also has an auto-lock feature if you want to use it. It works on a timer that you can adjust in the app. Just keep in mind that if the door is left open, you’ll need to unlock it again before closing it. You also have the option to turn off auto-lock completely. To set everything up, you’ll need to download the app. The app itself is pretty simple to use and lets you control the lock remotely, which is a nice feature. Overall, I highly recommend this lock—it offers a lot of features and flexibility for the price. As for downsides, the fingerprint scanner can be a bit finicky at times. I’ve found that using your thumb works the most reliably. Also, if the fingerprint scanner fails too many times, the lock will go into a security lockdown mode, sound a siren, and won’t work again until you unlock it through the app. This could be an issue if you have kids who like to play with it. Aside from those minor issues, it’s a great lock and definitely worth considering.

It's the complete package for Smart Locks
Color: Black
Set name: Lever Handle Set
Opening the package, I was pleased that it was so complete. Inside/outside door handles, keys, thumbprint pad, keyless entry, and more. The kit comes with everything you need to install this on your front door. The fit and finish is very good, and it looks like a professional installation. The Smart Lock averages 12-month battery (4 AA, not included), and a 24-month warranty and tech support. The Smart Lock communicates with your phone via Bluetooth, which has a range of about 6 feet. If you need to control the Smart Lock from a greater distance, you will need to order a Bluetooth-to-WiFi gateway for about $32. This will allow you to control the Smart Lock from inside the house and also if you are traveling.
