Product Overview
The Sifely Keyless-Entry Fingerprint Smart Door Lock revolutionizes home security with a blend of cutting-edge technology and everyday convenience. Designed for exterior, entry, bedroom, and interior doors, this digital electronic lock combines advanced biometric recognition with versatile access options to meet the needs of modern homeowners, rental hosts, and property managers alike. Whether you’re managing short-term guests or securing your personal living space, this smart lock delivers seamless control without sacrificing safety.
Powered by third-generation fingerprint technology, the Sifely smart lock unlocks in under 0.3 seconds—fast enough to keep up with busy mornings yet secure enough to deter unauthorized access. Beyond fingerprints, it supports six distinct entry methods: numeric passcode, wireless key fob, proximity card, smartphone app, traditional key, and the ultra-fast biometric sensor. This multi-layered approach ensures you’re never locked out, even during power outages or system glitches. The inclusion of a physical key as a backup guarantees peace of mind when other methods aren’t available.
For users seeking remote management capabilities, pairing the lock with the optional Sifely WiFi Gateway (sold separately) unlocks full smart-home integration. From anywhere in the world, you can remotely lock or unlock your door, generate temporary access codes for guests, and monitor real-time entry logs through the intuitive Sifely app or web portal. This feature is especially valuable for rental hosts who need to grant entry to guests arriving hours before check-in or allow cleaners into vacant units without being physically present.
Installation is designed to be straightforward and stress-free. No professional locksmith or complex tools are required—just a Phillips screwdriver and basic handyman skills. The reversible handle mechanism fits both left- and right-handed doors, expanding compatibility across various home configurations. With no drilling needed and minimal hardware changes, most users can install the lock within minutes directly over their existing deadbolt. The entire process takes less than 15 minutes, making it ideal for renters or those hesitant to make permanent modifications to their doors.

Benefits & Ideal Use Cases
This smart lock stands out for its adaptability across diverse user profiles. Short-term rental hosts benefit greatly from the ability to generate and distribute temporary passcodes without internet connectivity—meaning you can send access instructions to arriving guests ahead of time, even if cellular service is limited at the property. These codes can be set to expire automatically after a specific date or time window, reducing the risk of unauthorized reuse.
Self-housing residents appreciate the frictionless experience of unlocking with a simple touch or glance, particularly useful for parents carrying groceries or children returning from school. The autolock function adds an extra layer of reassurance, ensuring the door secures itself without requiring manual intervention. For individuals with mobility challenges or visual impairments, the combination of voice-guided prompts (via app integration) and tactile feedback makes daily use significantly more accessible.
Property managers handling multiple units find immense value in centralized control. Instead of visiting each location to issue keys or reset combinations, they can instantly revoke access, update permissions, or audit entry patterns from a single interface. This not only saves time but also enhances accountability and reduces turnover risks in high-rotation environments like student housing or corporate apartments.
Even during power failures, the mechanical override key remains fully functional, maintaining core security even when electronics fail. Combined with weather-resistant construction suitable for outdoor exposure, the Sifely smart lock performs reliably year-round in varied climates.
Important Considerations
- The Sifely WiFi Gateway—sold separately—is necessary to enable true remote access features such as locking/unlocking from outside the home, sharing digital keys with guests, and viewing live activity logs. Without it, the lock operates locally via Bluetooth or manual inputs only.
- While no drilling is required during installation, ensure your door meets standard thickness requirements (typically 1-3/8″ to 1-3/4″) and has a properly aligned strike plate. Misaligned holes may require minor adjustments prior to mounting.
- The package includes the main lock unit, internal components, mounting screws, and clear step-by-step instructions. Four AA batteries are not included but can be purchased separately.
- Before purchasing, verify compatibility with your current deadbolt assembly. While most cylindrical locks are compatible, older models with non-standard backsets or oversized crossbolts may require adapter kits not covered in the standard package.
- Smartphone integration requires iOS 12+ or Android 8+ and Bluetooth support. The free Sifely app is available on both major app stores and includes tutorials for setup and troubleshooting.

Great smart lock!
The Sifely Smart Lock is the Future of Home SecurityThe Sifely smart lock product is revolutionizing home security, making it easier and more secure than ever. With a sleek design, top-of-the-line technology, and a wide range of features, the Sifely Smart Lock is an ideal choice for those looking to keep their homes safe and secure. In this Sifely smart lock product review, we will explore the features and benefits of this impressive device and how it can help to enhance your home security.Product OverviewThe Sifely lock feels high quality in your hands. The device is heavy gauge steel with a plastic digital screen keypad, a biometric fingerprint scanner, RFID swipe keys, and custom emergency keys like you have never seen before. Emergency access is cleverly hidden and would not be easily guessed by a thief. One-time digital passcodes can also be issued, and an access log is accessible from the app that describes which code was used to gain entry, whether it be a biometric or RFID card, and who it is assigned to, along with the time and day stamp.InstallationInstallation is a breeze. Just remove your old lock and install the new one just like you would any other door lock. Only one wire is connected from one side of the door lock to the other.The system is self-contained and runs off of 4x AA batteries (not included). There are only about six total screws to install this device. Three screws for the keypad, two for the bolt, and two Allen screws for the actual door handle. The total time for a novice to install is about 10 to 15 minutes, of which you will probably spend 6 minutes looking at the instructions before you realize it is so simple you should have just started and guessed your way through. The door locks can only go together one way, so you must put in considerable effort to get it wrong.The biometric part is the same as installing a fingerprint on your cell phone through the app. Just assign a name, then tap the sensor with your finger and hit save. 30 seconds at most. The temporary numeric passwords are auto-generated and are also assigned a name by you and generate a text message you send to users that come complete with instructions and are only valid for the length of time and number of uses you assign. The RFID key cards are also simple; name the card and tap it on the keypad. It should take 10 seconds at most.Ease of UseSuper simple. No more wondering if you locked the door when you left the house or having to lug around another key. After you set it up, you can open the door lock with your fingerprint. The lock looks super slick, and everyone who sees me use it is always super impressed. Batteries last a good long while, and if you do have to replace them, there is only one small screw to remove.FeaturesDigital smart door lockPhone app access controlRFID key cards x 2 included.Unlimited biometric access (fingerprint)Unlimited temporary numeric passwords (user-dictated # of uses or length of time validation)Notifications when the door is opened to your phone (can turn on or off)Emergency alarm if wrong code or unregistered fingerprint is used too many timesEmergency shut down if the wrong code or unregistered fingerprint is used too many timesProduct reviewI have tried a great deal of these types of locks. Functionality varies greatly among manufacturers, and customer service is often times sketchy or nonexistent. I have to say my experience has been top-notch since day one. First, the packaging comes complete with all the parts the only two items you will need are a regular Phillips screwdriver (cross head) and 4 x AA batteries. I initially bought one for my front door about a year ago. Somehow the handle broke, and I wrote the manufacturer ( the contact email was right in the phone application). They responded within an hour or so to an email I sent, asking me to send them a picture of the bar code inside the battery cover and a picture of the damage, and within two days, I had a new door lock set at my front door!Amazing, no hassle, super quick, and very friendly. All along the process, they kept me informed of what they were doing when the new set was sent and gave me tracking truly exceptional service. The device feels very high quality with good heft, and the locks are very responsive and offer a ton of ways to control who, how, and when guests can access it, and the locks are very responsive. They auto-lock within a few seconds of unlocking, so you never have to be worried about someone coming into your home uninvited. One of the worst feelings is getting halfway to where you are going and having a feeling in your gut you forgot to lock the door. The application is very simple to use and has saved me a ton of times when I needed to give someone access to the house, like a family member or my housekeeper. I also like that you donât have to give someone a permanent access code, although that is an option also. You can give the access code just for an hour or one access attempt. The price is very fair, and the quality is very good. I would buy it again.

Great, but non-standard key is a pain
Wonderful Lock, Upgraded from a Schlage Pin lock that I’ve had for 10 years. Wanted a semi-smart lock that i can monitor who/when it was used by.Pros:Fingerprint Reader is fast, and you don’t need to worry about orientation of your fingerAccess cards work just as fast, just tap the front of the reader and your inSoftware is mostly intuitive, some hardware quirks are not appartent at first.Cons:to enroll any unlock option, the manual does not tell you you should wake up the door handle before you hit begin/start. this can be done by touching the pin pad area to light it up. This has to be done with any interaction with the app. once you do this however, it works fairly flawlessly.the key is a crescent shape with a standard tooth patern down the middle of the concave. to use the key, you have to remove the magnetic plate on top. the manual says you can press with your finger on the inner edge and it pivots out. my wife got it to do that ONCE. noone in my family has gotten it off that way since. the way that works, is you take the key, and push HARD on the inside edge, it will pop off that way just fine.It’s a good thing they give you 6 keys, because 3 Locksmith places didn’t have any tools to make replacements. it doesn’t make it any more Pick-proof, it’s a standard style tooth setup, so a good lock picker can still get in with a rake in no time. (this is true with any lock, Don’t fool yourself. Watch lock picking Lawyer)Despite my grumbles, I do love this lock. the wake for app part likely would be resolved if i bought the bridge piece, and I might just JB-Weld the Key access shut, I have that old Schlage Lock on the back door now, so i have a plan-B if it kills itself. Time will tell if it lasts as long as my old one.

Too much bulky and we canât lock the screen door. End up buying other smart door lock so better check the size.
