Nuki Smart Lock Ultra vs Philips Wi-Fi Smart Deadbolt DDL242X

Updated September 2026

Data from Amazon and official Nuki and Philips sites.

2026 verdict

Winner

$109.99

The Nuki Smart Lock Ultra is Nuki's fastest, most refined lock, but the Philips Wi-Fi Smart Deadbolt DDL242X still wins this comparison overall on price, weather resistance and a full set of built-in guest-code options, one-time, periodic and anti-peep passwords. The Nuki Smart Lock Ultra answers with deeper connectivity, adding Thread on top of its built-in Wi-Fi and Bluetooth, and a longer integrations list that spans Apple HomeKit, Google Home, Alexa, SmartThings, Home Assistant and Matter, well beyond the Philips lock's Google and Alexa voice support. Owner ratings and warranty length land evenly between the two, and the base lock-system tally ties as well, though Nuki's fingerprint and keypad still require its separate paid accessories where the Philips deadbolt builds both in from the box. Buyers chasing the most refined, best-connected retrofit lock on a European door, and willing to add Nuki's keypad accessory, should still reach for the Nuki Smart Lock Ultra; those who want fingerprint and keypad entry built in at a friendlier price should choose the Philips Wi-Fi Smart Deadbolt DDL242X.

Frequently Asked Questions

Which is better overall: the Nuki Smart Lock Ultra or the Philips Wi-Fi Smart Deadbolt DDL242X?

The Philips Wi-Fi Smart Deadbolt DDL242X wins the overall comparison on price, weather resistance and its built-in one-time, periodic and anti-peep guest codes. The Nuki Smart Lock Ultra answers with deeper connectivity and the longest list of native platform integrations of any Nuki lock, while owner ratings between the two are essentially even.

What is the biggest difference between the Nuki Smart Lock Ultra and the Philips Wi-Fi Smart Deadbolt DDL242X?

Smart-home reach versus built-in entry hardware. The Nuki Smart Lock Ultra connects to Apple HomeKit, Google Home, Alexa, SmartThings, Home Assistant and Matter over its own Wi-Fi, Bluetooth and Thread. The Philips Wi-Fi Smart Deadbolt DDL242X only reaches Google Home and Alexa, but includes a fingerprint reader and keypad directly in the lock rather than as accessories.

Does the Nuki Smart Lock Ultra include a keypad and fingerprint reader?

Not built in. Passcode entry needs Nuki's separate Keypad accessory and fingerprint needs the Keypad 2, both bought on top of the lock. The Philips Wi-Fi Smart Deadbolt DDL242X includes both a fingerprint reader and a touchscreen keypad out of the box.

How do their owner ratings compare?

They are effectively tied. The Nuki Smart Lock Ultra, Nuki's flagship model, earns ratings on par with the Philips Wi-Fi Smart Deadbolt DDL242X, so neither has a clear ratings edge.

Who should buy the Nuki Smart Lock Ultra?

Buyers on European doors who want Nuki's fastest, most refined retrofit lock with the widest native smart-home integration, and who are willing to add the Keypad accessory and pay a premium price for it.

Who should buy the Philips Wi-Fi Smart Deadbolt DDL242X?

Buyers who want fingerprint and keypad entry built in from the start, better weather resistance and a lower price, and who only need Google Home or Alexa voice control rather than the widest platform list.
