Smart Lock Ultra is one-third the size of previous Nuki models. According to the company, this is achieved with a new onboard battery design that eliminates the need for a large battery compartment. The lock features a new brushless motor similar to those used in electric vehicles, allowing the lock to be unlocked in less than 1.5 seconds, which could make it one of the fastest smart locks available.

Built-in Wi-Fi eliminates the need for a separate bridge, while Matter-over-Thread and Bluetooth connectivity options are also included. The lock supports all major smart home platforms, including Apple Home, Amazon Alexa, and Google Home. Battery life is rated at six months per charge, and charging is handled via the included two-meter magnetic cable.
