Clean up your keyring folks
on September 13, 2026

[This review was collected as part of a promotion.] It looked daunting when I first pulled it out of the box. I was surprised at how easy it was to set up. Had everything done in about 30 mins. Now I don’t have to worry about whether or not my child has their keys! 10 out of 10 would recommend absolutely wonderful product. I’ve not had it for very long so can’t comment too much on the battery life, but it seems to be going strong. Have had zero issues so far though :) also love that it has a mechanical keyboard for emergencies.

Easy install, easy setup
on September 13, 2026

[This review was collected as part of a promotion.] This lock gets a 10/10 from me. The installation was sooo smooth. We had a previous smart lock and the installation was god awful. This was such a breeze. The lock runs so smooth and the app is so cool! You can unlock your door from anywhere and set up personalized passcodes/fingerprints for everyone. I never had a fingerprint door lock but I am never going back. Seriously level A easy install and set up. I would recommend this lock to absolutely anyone.

[This review was collected as part of a promotion.] Took a bit to put on the door and set it up. I am really liking it so far. Locks and unlocks with no issues. It connects to the app perfectly. I have not had any issues since using it.

Modern smart lock for the win!
on July 2, 2026
Posted by: JessicaW
[This review was collected as part of a promotion.] This is a very neat and affordable door lock. I love that is has an app and it is easy to use. The installation wasn't as soon as I had hoped, I needed a little help I don't think everyone will have an issue with installation, I have been sick for months and I struggled with lining up everything while dealing with a chronic sinus infection. I got lucky with the design as it matched my door handle and I was able to move my old "dumb" code lock to my back door. Im so excited to have a beautiful smart lock front and center for my friends and family to use, if they ever need in my home! So far, zero issues with connection, functions or stability.

Secure And Convenient Smart Lock
on July 1, 2026
Posted by: HollyP
[This review was collected as part of a promotion.] I was pleasantly surprised by this Desloc Smart Lock. We have only ever had traditional locks on our exterior doors, and this lock adds technology and convenience that adds a sense of security and peace of mind to my day. The lock itself was nicely packaged and relatively easy to install. The lock is more on the bulky side, but that is due to the battery that is advertised to hold its charge for 13 months! I love that my children don’t have to carry a key around, and I can set a code for visitors to be able to gain entry to the house when they are here. However, there are also 2 backup keys provided. The fingerprint reader is setup on the actual lock and has worked without any issue. The locking mechanism when going in and out is also smooth and has functioned well without any issues thus far. I think my favorite part of this lock though might be the app. There are so many features… but you can even view realtime access logs or remotely lock/unlock the door! So far, it has held up and functioned in very hot and humid weather as well as rain. I am definitely happy with this lock and would recommend purchasing this for anyone in the market for a smart lock. It’s functionality and sleek design have left nothing more to be desired in my opinion.
