K3FW TTLock electronic lock


The K3FW TTLock electronic lock by Spreest is a modern and intuitive solution that provides convenient access control for your home or business.
In seconds, you can grant access to a guest with a one-time code, give an employee access only for specific hours, and check every attempted opening in the history – all from the app.
It is ideal for short-term rentals (Airbnb, Booking), offices, warehouses, or service points, where fast and controlled access without the owner's presence is crucial.
The robust construction and IP67 waterproof rating allow for outdoor installation – on doors or building facades, and the backlit LED panel enables convenient use even after dark.
Thanks to integration with the TTLock app, you can manage access remotely via Wi-Fi. The built-in network module provides remote access without the need to purchase an additional gateway.

2. 13.56 MHz IC Card – A convenient way to gain access by simply tapping the access card.
3. PIN Code – Allows setting unique passwords and granting access permissions valid within a selected time frame.
