Smart locks have started to feel less like a luxury gadget and more like a practical upgrade for people tired of hiding spare keys or dealing with lockouts. The Philips 4000 Series Touchscreen Fingerprint Smart Deadbolt leans into that convenience-first approach, and it's on sale for just $110.49 on StackSocial right now. It lands in the middle ground between cheaper keypad locks and the more expensive smart home systems that often require extra hubs or subscriptions.
The Philips 4000 connects directly over wifi and Bluetooth, so you can lock or unlock your door remotely through the Philips Home Access app without buying additional hardware. You also get a fingerprint scanner, so instead of fumbling for keys while carrying groceries or walking the dog, you can unlock the door with a tap of your finger. The lock can store up to 50 fingerprints and more than 100 PIN codes, making it practical for large households, Airbnb hosts, or people who regularly have cleaners, dog walkers, or guests. You can create one-time guest codes, check lock activity in real time, and receive alerts when someone enters or exits. Philips uses AES-128 encryption to store biometric data locally on the device rather than in the cloud, helping address at least some privacy concerns about fingerprint-enabled hardware. And if you’re a voice-command type of person, the Philips 4000 Series smart deadbolt also supports Alexa and Google Assistant.
That said, like many smart home devices, this deadbolt works over a 2.4GHz wifi connection, so setup may take a little extra effort on some newer mesh network systems. And while its IP54 weather resistance rating means it can handle dust and rain, it's not built for extreme exposure. For buyers looking for remote access, app controls, and fingerprint entry without jumping into a larger smart home ecosystem, this Philips smart deadbolt covers the basics well for the price.
What do you think so far?
And if fingerprint unlocking is not a priority, Philips also has a simpler version in the same 4000 Series for $93.49 on StackSocial. That model still gives you remote access through the app, supports up to 20 PIN codes, and allows unlimited one-time guest codes for visitors or deliveries.
