The K711 electronic smart lock by Spreest is a clever solution that allows you to turn a regular door into a smart access point. In seconds, you can grant a guest access with a one-time code, stress-free provide the cleaning crew access "for tomorrow 10-12," and after closing the door, the lock automatically secures itself - all without needing to take keys out of your pocket.
It's ideal for Airbnb rentals, self-check-in hotels, warehouses, or offices, where guests can be sent a code or e-key remotely, valid only during specific hours.
Automatic locking after closing the door eliminates the risk of leaving the door open, and the built-in memory supports 200 cards, 100 fingerprints, and 150 PIN codes – plus unlimited e-keys in the app. No internet? No problem – the handle works locally, and user data is stored internally.
The outdoor panel has an IP65 certificate, so there's no problem installing the handle in entrance doors exposed to weather conditions.
The batteries last for about a year. When the battery starts to run low, the lock will warn you, giving you time to replace it. The handle fits left and right doors 35-104 mm thick – wooden, steel, or aluminum.
