  • Convenience is the "Key"!
Style: WiFi Version Color: Black
We have an attached garage, but no direct passage into it from inside the house. Having to fumble with keys to unlock the back entry door every morning to go work, or even to do a load of laundry on the weekend used to be a pain--until now. Our cars have key-less entry, so why shouldn't the garage? I've been looking at smart locks with fingerprint readers for a while but most were too pricey or looked "clunky". This Sifely lock solved the problem. It's very sleek looking--no ugly buttons. The number keys are not visible until you touch the keypad. The lock has a quality, solid feel. But for me, the most important feature is the fingerprint reader. It works just like my old iPhone 6s, instant response, no waiting for the lock to "think". In fact you have several "key" options: fingerprint, a physical metal key, passcode or phone app. They also include the Wi-Fi gateway which allows you to control the lock from anywhere. The lock was very easy to install. It took me about 45-mins only because I had to remove the old doorknob and remount the old deadbolt in its place. Be aware that the manufacturer recommends mounting the smart lock in the upper position where the deadbolt usually is, which places the door handle a bit higher than usual. We don't have small children, so that's not an issue for us, but you should take this into consideration. You may need to deepen or enlarge the mortised cutout for the new bolt or the striker plate, and the old screw holes may need to be filled and re-drilled. The new striker plate was slightly larger than our old one and the screw holes didn't match up. So I simply swapped our original deadbolt's and doorknob's strikers--no drilling needed. The only issue I have is that the original doorknob hole is now occupied by the old deadbolt lock which looks odd. It would be nice if Sifely provided a matching cover plate to hide the old doorknob hole so that I don't have to remount the old deadbolt in the doorknob's place. For us, one lock is enough. The lock takes 4-AA batteries (not included). You download the phone app, set up an account and add the lock. It works with Bluetooth--I can control the lock from over 30-feet away. You can use the app to lock/unlock and to program passcodes, fingerprints, etc. You also install the included gateway with the app. The gateway is not required to use the lock locally, but you'll need it if you want to control the lock over the internet or just to check its status to see if it's locked. Keep in mind that the gateway has to be located within Bluetooth range of the smart lock. A USB power cable is included but it does not come with a USB wall adapter, which most of us probably have a few lying around the house anyway. I'm not sure how long the batteries will last in the lock. They say up to a year. It's probably still a good idea to keep a spare key available--just in case. Also note that the keys are not standard, much longer than common house keys. It has other features that I seldom use like programming a temporary passcode for a service person or house guest. RFID key fobs are included which I'll probably never use because the fingerprint reader works so well. In the short time that I've been using this lock, I'm impressed. I find myself just going in and out of the garage for no good reason just to play with it. I love the auto-lock feature and the (volume adjustable) audible/voice confirmation (both options can be turned off) so I never again have to wonder if I left the garage's back door unlocked. So far, it has worked flawlessly, and I highly recommend it. ... show more

  • Easy to use
Style: WiFi Version Color: Black
Feels like good quality. We love the fact there’s multiple ways to unlock. You could use all fingers on both hands if you wanted to. So far the only problem is sometimes I have to have the smart lock read my finger 1-3 times before it actually unlocks and other times it gets it on the first try. The passcode and key card work great. I have had the smart lock installed without batteries for 2 months since I did not have WiFi. When I got WiFi I was able to completely set it up and so far the app has not given me any issues. The installation process was pretty straight forward but for some reason I’ve had issues on both doors trying to change out the plates into the door frame because the locks no longer went into the holes in the door frame after I changed them but that may just be the way my door frame is built lol. Would recommend to anyone who might be a little tired of struggling to find your keys while you have other things in your hands. Also to anyone who would like to know when a door gets unlocked. ... show more

  • Convenience and quality.
Style: WiFi Version Color: Silver
I love this Door lock. I like that it can log who comes in and out of your apartment. You can give Each person their own fingerprint or code it came with five keys And for fobs. I ordered it in August but I’ve been using it since March and have had no issues. You can delete somebody’s fingerprint or passcode. You can put it on passage mode where it will stay unlocked for a certain time and then lock for a certain time or a certain day, there’s so much versatility with this door lock. I also got it with the gateway so you can do things remotely Would highly recommend. Very sturdy it didn’t fit my door lock perfectly so I had to do some adjustments.. Battery life is still at 100%. The fob didn’t stop working after a couple months so I need to order some new ones. Other than that, I love it for its convenience and for all of the other things that allows you to do especially being disabled and having different caregivers come in and out of my house at different times. You can lock it and unlock it via your phone as well as change passcodes or delete and add fingerprints. ... show more
