Unlocking the door in less than 1.5 seconds with just a touch is incredibly efficient and feels futuristic.

What truly impressed me was the variety of unlocking methods available. Beyond the fingerprint sensor, I can open the door remotely through the eufy Security app, enter a PIN via the keypad, use a physical key, or even unlock the door using my Apple Watch or voice commands through Alexa or Google Assistant. This flexibility is perfect for different scenarios—whether I’m coming home hands full, letting a trusted friend in remotely, or simply enjoying the convenience of voice control.

The built-in Wi-Fi capability means I don’t need to buy an additional hub or bridge to control the lock from anywhere. Setting it up was straightforward, and managing access, receiving real-time notifications, and checking event history all through the app adds a layer of control I didn’t have before. Plus, if you’re already in the eufy ecosystem, integrating this lock with a eufy doorbell to create automated routines is a huge bonus.

Installation was surprisingly simple, taking me about 15 minutes without any drilling.

3. Philips Wi-Fi Smart Lock with Handle, Keyless Entry Keypad Door Lock with Handle, Front Door Deadbolt Set with WiFi Gateway, App Control, Fingerprint Unlock, PIN Code Unlock, Auto Locking

When I first came across the Philips Wi-Fi Smart Lock with Handle, I was immediately intrigued by its comprehensive approach to home security combined with modern convenience. This smart lock is not just about locking and unlocking your door; it’s a complete upgrade to how I manage access to my home, blending style, technology, and practicality seamlessly. The fact that it includes a handle alongside the keypad door lock adds a sophisticated, coordinated aesthetic to the entryway, which I appreciate as it enhances the overall look rather than just serving a functional purpose.

One of the standout features for me is the ability to control my door anytime and anywhere through the Philips App. This means I’m no longer tied down to physically being near my door to check its status or grant access. Whether I’m at work, on vacation, or just in another room, I can lock or unlock the door remotely, receive real-time notifications, and even monitor who is coming and going. This level of control and awareness significantly boosts my peace of mind, especially when I have guests or service personnel visiting.

The versatility of unlocking options is impressive and really caters to different preferences and situations. The Philips Smart Lock offers five distinct methods through the App, fingerprint recognition, PIN codes, traditional keys, and even voice commands via Amazon Alexa or Google Assistant. Personally, the fingerprint unlock feature stood out as a game changer. It uses advanced biometric technology with 99.99% accuracy, allowing me to unlock my door in just 0.3 seconds with a simple touch. This is not only incredibly fast but also highly secure, eliminating the risk of lost or stolen keys.

Another aspect that I found very practical is the ability to create various PIN codes. I can generate unlimited one-time PINs for delivery people or guests, as well as set permanent, recurring, or temporary codes tailored to specific needs. The security benefit here is clear — once a one-time code is used, it automatically expires, so I don’t have to worry about unauthorized access after the fact. This flexibility gives me confidence in managing access without compromising security.

The auto-locking feature adds another layer of protection that I’ve come to rely on. Knowing that the door will automatically lock itself after a customizable timer (between 30 to 180 seconds) means I don’t have to second guess whether I remembered to lock up when I leave. This is especially reassuring when I’m in a rush or distracted, as it ensures my home is always secure without extra effort.

Installation was surprisingly straightforward and user-friendly. The lock fits most standard doors, ranging from 1-3/8″ to 2″ thick, and comes with optional screws for added security if the door is weak or warped. I appreciated that the installation only required a screwdriver and took just minutes, making it accessible even for those who aren’t particularly handy. It’s important to check compatibility before purchasing, but once you do, the setup feels intuitive and hassle-free.

Finally, Philips’ customer service deserves a mention. Knowing that reliable phone support is available during extended hours on weekdays and Saturdays, coupled with 24/7 email assistance, gives me confidence that any questions or issues will be promptly addressed. This kind of support is crucial when investing in smart home security products, and Philips seems to have that covered well.
