Easy to install and works perfectly
This smart lock exceeded my expectations! It’s super convenient and gives you several ways to unlock — fingerprint, keypad code, key fob, or traditional key. The fingerprint sensor works quickly and accurately, and it’s great having backup options for guests or kids who might not use the app. Installation was simple, and the lock feels sturdy and high quality. I really like the sleek design too — it looks great on the door and works flawlessly. Definitely worth it if you want security and flexibility in one.

Good and affordable lock
This is my second Sifely. I recently installed the Door Lock on my front door and have been very impressed with its functionality and value for the price. Here's a breakdown of my experience: **Pros: *Easy to install: The lock comes with clear instructions and minimal tools required, making it a great DIY option for most homeowners. No drilling is needed for the standard installation. *Multiple unlocking options: The 5-in-1 keyless entry is a great feature. I can unlock the door with my fingerprint, code, fob, smartphone app (with an additional gateway), or even a physical key for backup. This provides flexibility and convenience for different situations. *Affordable: Compared to other smart locks on the market, the Sifely offers a comparable feature set at a competitive price point. *Auto-lock function: I never have to worry about forgetting to lock the door, as the auto-lock function ensures it's secure after I close it. **Cons: *Remote access: If you want remote access features like locking/unlocking your door through your smartphone from afar, you'll need to purchase an additional gateway. *Fingerprint: sometimes I have to put my finger twice, since is not recognizing at the first attempt. **Overall: If you're looking for a budget-friendly smart lock with core functionalities, the Sifely is a great option to consider.

Fun little lock to have.
This is a fun little lock to have in your house. It was very easy to install (took maybe about 20 minutes) and it works exactly as advertised. I was pleased enough that I bought two of them for my house. The fingerprint reader option may take a few attempts if you don't place your finger exactly in the middle of the reader but the way around this is just to create multiple records of your fingerprints. They actually recommend this for children and the elderly. All in all, not a bad product to have and it does look very nice.

Sifley Deadbolt Lock
This lock is so nice and the options make it very versatile. Fingerprints, codes, fob, key, plus you can use your phone to lock/unlock. The app makes it simple to setup also. All in all this Sifley lock was an excellent choice.

Fast, Secure, and Easy to Use Smart Lock
Super impressed with the Sifely Model O Smart Lock. Installation was quick with just a screwdriver, and the lock feels sturdy and well-made. The fingerprint reader works fast and accurately, the keypad is bright at night, and I love being able to send temporary codes to family or guests through the app. Auto-lock gives me peace of mind, and the design looks sleek on my door. Overall, a great mix of security and convenience—highly recommend!

Great purchase
Love this lock! It was super easy to install and to set up codes for everyone and it looks great. The fingerprint reader works great too. We do not currently have the hub, but for our uses we really do not have to have one. We may get the hub down the road to be able to add ALEXA. It is so nice to not have to take my keys with me anytime i go out. Highly recommend and would definitely purchase again.

Great keypad deadbolt
Product is easy to install due to the detailed instructions and video clips. Pros: installation and initial setup; several options for unlocking Cons: finger print reader has failed setup on numerous attempts; sound options controls both voice and keypad clicks. I would like to have the ability to hear the key clicks but not the door locking status messages being announced. I would definitely recommend the lock. Update: the finger print reader works perfectly. After reviewing the instructions, I did not follow the recommended steps which caused my initial issue with setup.
