K3FW TTLock electronic lock


The K3FW TTLock electronic lock from Spreest is a modern and intuitive solution that provides convenient access control for your home or business.
In a few seconds, you can grant a guest access with a one-time code, give an employee access only for specific hours, and check every attempt to open in the history - all from the app.
It is ideal for short-term rentals (Airbnb, Booking), offices, warehouses, or service points, where quick and controlled access without the owner's presence is crucial.
The solid construction and IP67 waterproof rating allow for outdoor installation - at doors or on the building's facade, and the backlit LED panel allows for convenient use even after dark.
Thanks to integration with the TTLock app, you can manage access remotely via Wi-Fi (with a gateway) or locally via Bluetooth - quickly, conveniently, and securely.
