    This lock is wonderful

    Really stepped into the future with this lock, I walk up wave my hand and it just unlocks the door how sweet is that. I have it programmed for both my hands. My mom's hands. And the best part of all my girlfriend's been wanting a key to my house. And I haven't wanted to give her one this lock gives me the ability to give her a code and set up her handprint and I can take away the ability for her code and handprint to unlock the door and reactivate it whenever I want. You can change how fast the lock automatically relocks. I really love this thing. It looks good and it functions well. Super easy to install. And it also works with a key just incase. Highly recommend

    Great Smart Lock.

    My friend has been using this DESLOC K140 Plus at his home, and after seeing how convenient the palm vein recognition and auto-lock features were, I decided to buy the same one from Best Buy. The setup was straightforward, and I really like the keyless entry and large battery capacity.

    Great looking

    I love the sleek look and clean lines of this lock. I have a new door coming, but I already temporarily tried this on another door. The palm scanner is awesome. Great price and works well

    Super convenient

    This has a super easy set up. I have a fact that I could just swipe my hand up and my door unlocks. I love that it has so many different settings. If you have a family that requires a caregiver, then you can set up their own password, and it even shows who unlocks the door on the app. I also love that you can do a one time passcode set up so if you have someone coming over for the day like a dog sitter or something that has to be set up for them and then it will erase. We also have four family members on their set up right now with passcodes and also the hand recognition which makes us really easy for our kids.

    Security In The Palm Of Your Hand

    There's so much to say about this, with so little time. 1st. Put this lock in your cart, and read this review while you shop for other things to buy along with it. This is a go. Yes. I did give it a 4 out of 5. Not a full 5, because as with many of these locks. You may not be able to use it, if you live in an apartment complex. and one other thing, that I'll get to later. Coming from someone who dwells within an apartment. There are exceptions. The main thing is that it comes with keys. These can be copied for your management or your kids. Whichever is needed, and when the power goes out. Also, if you've come across my reviews before, you know that I loves me some easy installs. And this one makes me feel like a professional. As long as you know your own WIFI password, you're off to the races. It's boxed with everything you'll need, outside of the one screwdriver that you'll definitely need. You don't have to drill any extra holes, unless you have a rare occasion, where your deadbolt is a bit off. It'll still fit. It just requires some minor adjustments, which the instructions will walk you right through. The battery is huge and long-lasting. This is where I have my other problem. There's no charging cable to charge your battery. Yes it's pretty charged, right out of the box, but once it's depleted, you'll need to make sure that you've got USB-C cable laying around. However, in the extreme case that you don't have a key on you, and the power's out, there's actually an emergency type C cable to plug into your power bank to access your dwelling. So, go add a power bank to your shopping cart now. The palm reader is super cool and you can also assign users and safety parameters for when people are supposed to be home and they for some reason, don't show up on time( And where have you been, between the hours of "ya should've been here" and "Oh my goodness, you're late"?). The app keeps track of al of that. The screen is motion sensitive, so when you get close to it, the screen will come on. Not to mention, it works with Alexa and Google Smart Home. Finally, I'm just gonna say that I love that hide-away key hole. Enjoy your new lock.

Questions & Answers

  • Does this work with CPI security

    Thanks for your question and for your interest in the DESLOC K140 Plus! The K140 Plus does not currently integrate directly with the CPI Security system. However, it features built-in Wi-Fi and works independently through the DESLOC app, so no additional hub or bridge is required. You can still enjoy convenient remote access, smart controls, and other connected features directly through the DESLOC ecosystem.

  • Do you recharge the battery or throw it away after the 9 months? If rechargeable, how do you recharge it?

    Yes, the battery is rechargeable — there’s no need to throw it away after 9 months. K140 Plus uses a removable rechargeable battery with a Type-C charging port. You have two convenient charging options: you can remove the battery and recharge it separately, or keep it installed in the lock and connect a power bank directly to the battery, so the lock can continue working while charging. We also plan to offer spare batteries in the future, making it even easier to swap batteries without any downtime. The lock provides low-battery alerts in advance. If the battery is fully depleted while you’re outside, there is also an emergency charging port on the exterior side, which can be temporarily powered using a phone or power bank to unlock the door.
