Which Smart Lock do I have? This article helps you distinguish all Nuki Smart Lock generations. In general, there are two types: Smart Locks with built-in batteries and Smart Locks with removable batteries.
1) Smart Locks with built-in batteries
This is the newest Nuki Smart Lock generation. These Smart Locks come with all the features of previous Smart Locks, like Matter support or a built-in Wi-Fi, so that you do not need a Nuki Bridge to bring it online. The most recent feature of this generation is the option to restore a backup from a previous Smart Lock.

2) Smart Locks with removable batteries or the Nuki Power Pack
