Keyless-Entry Fingerprint Smart Door Lock: Sifely Digital Electronic Lock with Code Passcode, Electric Door Knob, Biometric Door Handle, Perfect for Exterior/Interior/Entry/Bedroom Doors (Silver)

I love this lock. It works great - has lots of features other smart locks don’t have. It has a digital keypad and you can set it up with a code, fingerprint or card access. All work great. It also has an app so you can set it up thru the app - which is super user friendly. You can even lock and unlock the door with the app - but to use that feature more than 10 feet away I think you need to buy the gateway - for about $40. . You can set up a large number of different users and with the app you can identify them by name etc. . You can set up temporary codes - like for a repairman to access your house. I love the passage mode which lets you leave it unlocked as long as you want - this is great when have workers going in and out all day during remodeling and the like. Most smart locks let you set a delay of 2-5 minutes before it locks but don’t have this passage mode feature. Customer service is great on replying and helping.I Also love the integrated handle - some digital locks have a separate handle and they may not install right with your existing holes - so you end up with open holes exposed or having to get a new door - so be careful with that. This one for right in my existing holes and allowed me to put a separate deadbolt on top.I can’t say enough about how great this lock is. And the price is excellent. Try and buy a lock like this at Home Depot and it will cost you $300.Warning - Digital Locks and the Sun: I had bought another lock when the buttons.on my old digital lock kept getting stuck but that new lock had a problem in that batteries died in 2or 3 days. Bought it again thinking it was a lemon but the replacement had the same problem. Finally figured out it was the 2 hours of morning sun hitting my East facing door that was causing the problem. This lock does not have that problem. It’s been working great now for 2 weeks.

Great door lock! Works perfect with combination or key fob. Easy to change combination with app. Great for vacation rental properties or even personal homes. Also good to give shippers code so deliveries are put inside door instead of left outside in weather and open to porch pirates.I have purchased and use three and have them on two different homes.

First, just in case they are dealbreakers for someone, the shortcomings: 1. I bought this in part because it had a Schlage key system. Unfortunately the lock apparently cannot be rekeyed, per an answer I found on the company's website. That means carrying around more keys if you want a non-electronic backup for entry. 2. You can apparently enter as many wrong codes or wrong fingerprints as you like without the lock creating a timeout. It will, however, create a record of the incorrect attempts.As to the unit itself, it offers a number of ways of gaining entry, including a keycode which can be of different lengths, and which unlike some other locks does not let the user know that it is wrong until they hit the # button (more secure). In addition to the keycode, the fingerprint scanner seems to work quickly and well, two near field tags are provided, unlock from the app, and you can apparently connect it to smart systems like Alexa (optional and insecure). You can also buy optional remote controls, which are similar to small garage door openers. It also offers a privacy button you can hit from inside, which turns off all these "smart" ways of operating the lock (traditional keys excluded), presumably intended for while you're home sleeping at night. This privacy button automatically turns off when you exit through the lock.It does have a way of having the lock stay open for a variable amount of time after unlocking (default 5 seconds), and also of scheduling times of day when the lock will stay unlocked. What it doesn't have is a way of unlocking the door at a given time you may want to be going in and out a lot, but for those with fingerprints scanned into the lock that is a minor issue.Unfortunately the instructions are not great, but they are supplemented by the screw packets being labeled for what step the screws are needed. Also, a second set of screws is provided, although not labbled with each step. One minor nice feature is the inside portion has a backer plate which is screwed in place to hold the outside portion in place. That makes installation slightly easier, and is probably a bit more secure. Also the batteries (4 AA) can be replaced without removing a single screw.Overall this is a better keypad lock than the approximately 15 year old Schlage keypad lock which it replaces. This keycode system is much more secure (Schlage may have updated that since I purchased), and the available fingerprint option a nice fast option to have. The only thing I will miss is the ability to just set the lock to unlocked on a whim, and the ability to rekey the lock.
