Solid lock with amazing features!
We are leaving for a trip in a week and we needed a more secure, reasonably-priced smart deadbolt lock for our new house. we wanted to install it before we left for our peace of mind. When we saw Sifely now offered a deadbolt on Amazon, we immediately bought it. It came safe and sound, compactly packed. the product was in great shape. It came with clear and precise instructions on how to install and use the app and all its features. We have been using a Sifely smart door lock for our garage door for a couple of months now, and it is amazing. it hasn’t given us any problems whatsoever. One little thing that irks, but is one of the best features of these locks, is that for the fingerprint scan your finger has to be placed in the same direction and spot as you placed it when saving it in the system in the first place. even a slight change in the angle or placement of your finger will not let you unlock the door. Additional security, I suppose, but sometimes when in a hurry, it takes me a couple of tries before I get my door to open. All the rest of the features of this lock are also amazing. It comes with a pair of keys, two key fobs that have to be paired with the lock, and the lock system itself. Another thing I was greatly pleased by is that one key fob can be paired with more than one lock. As I said, we had the same brand’s lock on our garage door already, and I like to carry a key fob paired with that lock already. When we got this lock, I was worried I would have to carry two different fobs now for the two doors, but then we thought to try and pair the same fob to both doors, and it worked like a charm!

Good addition to my smart lock family
Been using the Sifely gateway and lock on my front door for a while now, but hadn’t gotten a deadbolt because I wasn’t liking the existing designs and contacted the company to see if they had a similar design to my existing lock but in deadbolt form — they didn’t, but said they’d contact me as they were working on one that was due to release a few weeks later. I’ve heard this before and never hear anything back from the company, but not here, they contacted me the day the new lock was released and I jumped right on it.It’s perfect, it matches the design of the lock I use for the door and provides extra security and peace of mind, it was just as easy to install as the previous lock and packaged very well, within about 5 minutes it was all installed and setup to work with my existing gateway. Using the app I can actually make it so both locks will unlock with the same cards, but it would be really cool if you could “link” two locks so both would unlock when one was unlocked. Perhaps a future version of the app could do this?As far as usability goes, it’s great, the key cards work without having to get directly next to the lock, I have one on my ski jacket zipper so I can unlock the door without taking my gloves off or digging into my pockets, the physical keys are nice to have if things go wrong, and since I have a bit of experience with locks I re-keyed the new lock so the keys work in both locks. The fingerprint reader is a bit sensitive and fails about 20% of the times I use it, but I don’t mind that, I’d rather it be too picky than not picky enough. I’ll definitely be considering this brand when moving my apartment complex’s locks to smart locks this summer.

Great Quality and Easy Installation
I ordered this model after previously purchasing another model with a handle. They are the same brand and the app works great. Remember to get the modem in addition. Love all the passcodes I can program.

Highly intuitive and user-friendly lock
For a few months now I had a Sifely lock for a different door but not a deadbolt one. Sifely didn’t have a deadbolt version then which bummed me out because I actually really liked the operation of my current door lock. So when Sifely came out this deadbolt lock with all the same features, I was very excited.Cons: The only con was in the step involving attaching the baseplate. This took me a while because the screw and the hole weren’t lining up when going through the latch. Ultimately I loosened up the screws connecting the latch to the door and that gave me enough wiggle room to connect the baseplate. After that I tightened up the latch screws and everything was fine. It’s more of an inconvenience than anything else.Pros: I love the different ways in which you can lock and unlock the door – tags, fingerprint, keys, passcode, app, remotely – but also how you can remove most of these if you’re more concerned about security. The app is really intuitive and I love that I can control all my doors through this one app now.I would highly recommend this lock.

Works as intended
I thought the install process for this lock was pretty straightforward despite my inability to read instructions. Also the app has a lot of neat functions for setting multiple passcodes and fingerprints. Iâm of the belief that you donât need an app for everything but this actually makes sense. Ultimately youâre getting a pretty useful device. Takes a bit getting used to on how to initiate the keypad and make sure youâre using full charged batteries. Had some issues initially but I realized somebody had put bad batteries into my battery box

Sifely is a great company with great products!
This is my fourth lock from Sifely, and I’m very happy with them. These locks have many features that can accommodate everyone. The only down side to this particular lock is that it has a more plastic/cheaper feel to it, but works great and has all the features like all the other locks that Sifely makes.Go get yours today and thank me later, your welcome!
