S4A-K18 cabinet lock


Discover a new dimension of security and convenience with the S4A-K18 fingerprint furniture lock by Spreest. This elegant and discreet solution protects your drawers and cabinets from unauthorized access, while providing instant unlocking with a single touch.
Key Features
1. Biometric verification – The lock responds instantly when a registered finger is placed on it. A green LED indicates success and immediately unlocks the mechanism – all in less than a second.
2. Supports up to 20 fingerprints – Register the fingerprints of your entire family or team. Each user can have their individual access – without the risk of losing keys or forgetting codes.
3. Compact and elegant design – The scanner module is small and slim, making it perfectly blend with modern furniture. The main lock unit fits conveniently into a standard drawer, taking up no space.
4. Factory reset – A single long press of the button is enough to restore the lock to its initial settings. An ideal solution when you want to change users or transfer the device to others.
5. Hybrid power supply – The lock runs on 4 AAA batteries (alkaline), and in case they run out, you can emergency connect a power bank via the USB-C port and still unlock the cabinet. You will never be without access.
6. Automatic low voltage alarm – When the battery level drops, the lock will notify you with a flashing red LED – you have time to calmly replace the batteries and avoid being locked out.
7. First start-up – The first start-up allows you to quickly register two fingerprints, and adding more is done with a single button. Clear LEDs inform about the registration process.
