No lock hole design, it completely abandons the traditional key and lock, open and close by remote control or APP, realized real security. It supports touch design, it can be locked and unlocked by touching the lock body when indoors. Add USB external power source function. Make sure the lock works when battery was dead (battery not included). Four unlock modes optional: Phone APP unlock, Remote control unlock, indoor Button unlock, indoor Touch unlock. Tiger lock method, more stable and safe. Easy installation on all kind of doors, very convenient.
