KB3F TTLock safe
The KB3F TTLock safe by Spreest is a smart and secure solution that allows you to store keys and valuables without the need for physical handover.
In seconds, you can grant a guest access 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's ideal for short-term rentals (Airbnb, Booking), offices, warehouses, or service points, where quick and controlled access without the owner's presence is essential.
The solid metal construction and lockable cover protect the contents, and IP65 waterproof rating allows for outdoor installation – on a door handle, in a garage, or at a gate.
Thanks to integration with the TTLock app, you manage access remotely via Wi-Fi (with a gateway) or locally via Bluetooth – quickly, conveniently, and securely.
Opening methods
1. Fingerprint – Quick entry thanks to fingerprint recognition (up to 100 fingerprints).
2. PIN code – Enter your own code and enter without keys (up to 250 codes).
3. Mobile application – The safe opens with one click on your phone.

Low battery alarm
The safe is equipped with a low battery alarm, which allows you to monitor the power status in real-time. A notification will be sent to the application about low battery levels of ≥20%, ≥10%, ≥5%, and on the safe itself, a red light will flash after it is unlocked (3 blinks).
The device is powered by three AAA batteries or two CR123A batteries, which can last even 9 to 12 months in standby mode, minimizing the need for frequent battery replacement.
