1. Emergency power supply through USB: How to open the door when the smart lock is out of power? Smart locks generally have USB charging, and most of the current mobile phones are difficult to be played with by everyone for a whole day. Therefore, many people will carry USB and power banks with them. I have to say that this is a good habit. At the lower end of the front panel of the smart lock, there is a USB power supply hole, which can be used to open the door through the power bank function.
2. Emergency mechanical key to open the door: Smart locks generally have emergency mechanical keys. If the smart lock is out of power and cannot open the door, you need to use the emergency mechanical key to open the door. The keyhole of the smart lock is either in the lower middle part of the front panel or at the bottom of the front panel. When you use the smart lock, remember to put the emergency key in the office, in the car or with a good neighbor.
3. Find a locksmith to open the lock: The smart lock is a C-level lock core that is difficult to be unlocked by technology, but it does not mean that it cannot be unlocked by technology, but it is more troublesome. However, since the location of the keyhole design of the smart lock is not very convenient, this method is not very applicable overall.
