For sale: A new smart lock for the exterior door, suitable for homes and apartments. It is new and has not been installed, used, or tested for installation. It is waterproof and weather-resistant, suitable for the exterior doors of a home, office, or rest house. It opens with fingerprint, passcode, app, and the cards shown in the picture, giving you greater convenience without the need for keys. However, you can also open it with a key if, God forbid, the battery runs out. All its accessories are present as shown in the pictures. I have never used it; it was a gift assuming it was for the interior of the house, but it is for the exterior. May God bless the serious buyer.
