Electronic lock cylinder DS01 TTLock by Spreest is a modern and convenient solution that in a few moments turns an ordinary door into a smart access point . You open it without keys — with a code, card, fingerprint or e-key in the app. A one-time code for a guest, timed access for the cleaning crew, or automatic locking after closing the door – everything happens quickly, stress-free, and completely secure. The lock is perfect for short-term rentals (Airbnb) , self-check-in hotels, offices, or warehouses, where you can remotely grant access valid only during specific hours. Automatic closing after slamming eliminates the risk of leaving the door open, and the built-in memory allows you to store 200 cards, 200 fingerprints, 200 PIN codes and an unlimited number of e-keys in the app. The lock also works offline, so access and user data are always secure. The panel can be mounted outdoors, but it should be protected from direct contact with rain e.g., under a roof or use a protective canopy. Battery power lasts for approximately months of operation, and the system notifies you in time when the battery is low. Fits left and right doors with a thickness of 35-55 mm, made of wood, steel or aluminum. Opening methods Fingerprint – quick entry thanks to fingerprint recognition.
