Electronic Lock Handle A209B 50/72 TTLock Black


The A209B electronic smart lock by Spreest is a clever solution that allows you to transform ordinary doors into a smart access point, where you can instantly grant a guest access with a one-time code, stress-free provide the cleaning crew with access "for tomorrow 10-12," and the lock automatically closes when the door is shut – 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 the door closes eliminates the risk of leaving doors open. No internet? No problem – the handle works locally, and user data is stored internally.
The panel can be mounted outdoors, but it must be protected from direct contact with rain, for example, under a roof or with a protective canopy.
Batteries last for about a year of operation. When the battery starts to run low, the lock will warn you, giving you time to replace it. The handle fits left and right-hand doors 45–75 mm thick – wooden, steel, or aluminum.

Installation
You can install the handle yourself in most apartments and houses; it fits doors 45-75 mm thick, both left and right-handed, made of wood, steel, or aluminum.
The box includes a set of screws and spindles that allow you to mount the handle on doors with a thickness of 45 mm to 75 mm.
The handle works with standard mortise locks – so you can mount it on an existing mechanism without replacing the entire fitting.
NOTE!
The mechanical lock is not included in the set. However, if your door is already equipped with a lock, simply transfer the spindle and screw on the handle to immediately enjoy smart access.
Low Battery Alarm
The lock is equipped with a low battery alarm, allowing you to continuously monitor the power status. A low battery notification will be sent to the app at ≥20%, ≥10%, ≥5%, and a red light will flash on the lock itself after unlocking (3 flashes).
The device is powered by four AA batteries, which can last for up to 9 to 12 months.
