Nuki’s one-touch retrofit smart lock got its first-ever discount

The Nuki Smart Lock is the best retrofit smart lock currently available for people who want a minimalist, feature-packed upgrade to their preexisting deadlock. It’s currently selling for $149 at Amazon — its cheapest price ever — during the Big Spring Sale. Its fast unlocking speed, Matter-over-Thread support, and broad smart home compatibility impressed my colleague Jennifer Pattison Tuohy, enough for her to consider it the most advanced model she’s tested in her review.
Nuki Smart Lock
The Nuki Smart Lock makes it easy to upgrade your home security system without replacing your entire lock. It installs in minutes and can even sense when you’re approaching, automatically unlocking the door for you. It supports every major smart home platform through Matter, and you can easily share digital access with friends or family — perfect for when you’re on vacation and need someone to water the plants.

$199 $149 at Amazon

The Nuki Smart Lock’s pricing history is a bit confusing. It originally launched for $159.99 when we reviewed it in July 2025. Months later, the company raised the cost to $199.99 while addressing some of our major criticisms, namely that a paid subscription ($5.90 per month) was no longer necessary to remotely unlock the Nuki over Wi-Fi, or to receive lock activity notifications. By purchasing one now, you’re getting the best-ever price with all of the features we wish were available at no cost from the beginning.
For what it’s worth, you never needed to pay for the subscription to get access to some of the Nuki Smart Lock’s best features. As mentioned earlier, it supports a Matter-over-Thread connection, which is free to use (assuming you have a Matter hub and a Thread border router) and yields huge battery savings compared to controlling the Nuki Smart Lock solely over Wi-Fi.
