Popular European astute fastener shaper Nuki has announced the 5th procreation of its astute lock. The Smart Lock Ultra is simply a 3rd the size of the archetypal Nuki, features a caller brushless centrifugal for faster operation, and promises astatine slightest six months of artillery life. Plus, for the archetypal time, the caller fastener has been designed to enactment with US deadbolts.

The Nuki Smart Lock Ultra (€349) volition beryllium disposable successful Europe successful December and is the company’s archetypal full-replacement doorway lock. Previous Nuki models could beryllium retrofitted implicit an existing lock, truthful you could support utilizing your existing keys. This 1 requires swapping retired the full cylinder and comes with 3 caller keys. However, the US model, coming adjacent year, volition enactment arsenic a retrofit fastener and lone necessitate replacing the thumb crook connected your doorway — akin to however the August astute fastener works.

Martina Stix, Nuki’s communications manager, tells The Verge that the US mentation looks identical but comes with a antithetic mounting sheet and nary replacement cylinder — truthful you tin usage your existing keys. She says it should beryllium disposable successful Q2 of 2025, with pricing inactive to beryllium determined.

The large alteration present is that the Nuki Ultra packs each of the functions of the erstwhile exemplary into a overmuch smaller plan acknowledgment to a caller built-in artillery that does distant with the bulky artillery compartment. The institution says it’s besides implicit 3 times faster — susceptible of locking oregon unlocking successful nether 1.5 seconds.

That’s precise fast; the fastest locks I’ve tested instrumentality 2 to 3 seconds to afloat unlock, and astir are person to five, particularly retrofit locks. Stix says the velocity comes from an all-new motor: “The caller astute fastener is powered by brushless motor technology, commonly utilized successful electrical cars, utilized for the archetypal clip successful a Nuki astute lock.”

The fastener tin beryllium controlled successful respective ways: with a key, with geo-fenced-based auto-unlock, with the Nuki app connected a telephone oregon smartwatch, oregon with immoderate compatible astute location platform. It besides works with each existing Nuki accessories, including a key fob and a abstracted Bluetooth keypad mounted extracurricular the door, with the enactment of a fingerprint reader.

The company’s existing keypad accessory does not enactment Apple’s Home Key function, which allows you to pat your iPhone oregon Apple Watch to an NFC-enabled fastener oregon keypad to unlock it. Stix says Nuki plans to enactment Aliro erstwhile it launches adjacent year, a caller modular for astute locks that is reported to see a akin tap-to-unlock capableness to Home Key, though the specification has not yet been released.

Unlike immoderate erstwhile generations of the lock, Wi-Fi connectivity is built into the Nuki Ultra, truthful determination is nary request for a abstracted bridge. The caller artillery exertion promises up to six months of artillery beingness (possibly more, depending connected your connectivity choice; Thread oregon Bluetooth volition past longer than Wi-Fi). But it does person to beryllium charged connected the door, which seems a spot awkward. The institution supplies a two-meter magnetic powerfulness cablegram to scope a adjacent outlet and says it tin afloat complaint successful nether 2 hours.

The Smart Lock Ultra is disposable for preorder present at Nuki.io in Europe for €349 and volition vessel successful December. The US mentation is expected to motorboat adjacent year.
