Nuki Smart Lock Pro vs Philips 4200 Series Smart Deadbolt with Door Lever

The Philips 4200 Series Smart Deadbolt with Door Lever comes out ahead overall, thanks to weather-rated construction and a keypad built in from the start that covers one-time, scheduled and anti-peep passcodes. The Nuki Smart Lock Pro still wins on smart-home breadth, with native Matter, Apple HomeKit and Samsung SmartThings support the Philips lacks.

The Nuki Smart Lock Pro is a retrofit unit that mounts over an existing European euro-cylinder and needs its optional Keypad accessory for passcode or fingerprint entry, while the Philips 4200 Series Smart Deadbolt with Door Lever is a full US deadbolt replacement that ships with a fingerprint reader, keypad and matching door lever already built in.

The Philips 4200 Series Smart Deadbolt with Door Lever includes a fingerprint reader and a backlit keypad in the base unit, along with one-time, recurring and anti-peep passcodes. The Nuki Smart Lock Pro supports passcode and fingerprint entry too, but both require buying its separate Keypad accessory first.

The Nuki Smart Lock Pro is the broader smart-home player, with built-in support for Matter, Apple HomeKit, Samsung SmartThings and Home Assistant on top of Alexa and Google Home. The Philips 4200 Series Smart Deadbolt with Door Lever covers Alexa, Google Home and Home Assistant through a community integration, but does not support Apple Home, SmartThings or Matter.

Choose the Nuki Smart Lock Pro if you have a European euro-cylinder door and want a fast, tool-free retrofit that plugs straight into Matter, Apple HomeKit, SmartThings and Home Assistant, plus geolocation auto-unlock as you approach the door.

Choose the Philips 4200 Series Smart Deadbolt with Door Lever if you are replacing a US deadbolt and want fingerprint, keypad, app and key entry along with a matching door lever in one box, with weather-rated hardware and flexible passcode options built in rather than sold separately.
