Bold's Elite range retains the features of the previous generation of Bold Smart Lock such as its maximum-rated SKG*** security rating, and compatibility with smart assistants like Google Home and Homey, but also improves upon its predecessor across a number of areas, both with enhanced internal mechanisms to improve the robustness and security of the lock itself, and by offering a richer suite of software and security features for improved safety and peace of mind. These software features include real-time lock status to notify you whether your door is locked or unlocked, tamper detection designed to detect suspicious movements like banging or attempted forced entry, and push notifications if the door is left unlocked overnight. The Elite range also introduces Matter support, meaning that the Bold Elite locks can be easily integrated into a wider Smart Home installation with devices from other manufacturers like Shelly.

Access control can also be effortlessly shared between users, offering either scheduled or full-time access, making it a great solution for commercial spaces like offices as well as residential installations. The lock itself supports a variety of methods of unlocking, either by being physically close to the lock and having the app on your phone, or by using the optional Smart Clicker (sold separately), a physical button that can be attached to a key chain. For fully remote access control, the Bold Connect can be purchased separately and enables remote access locking and unlocking for one or multiple smart locks - ideal for deliveries and guests.
