you just return from work or from mall then you want to open your door but suddenly you cant open your door because your digital lock is run out of battery. So what can you do in order to go in?
Well you need to change the battery first then you can enter your house but there is the another way which you only need Powerbank and USB then connect it to the digital lock so that you can open your door.
Then how to avoid this from not happen again?
Actually every digital lock has it own way to tell you if the battery is empty for example songs, human voice and alarm sound
- For song: got some nice song telling you that battery is low
- For human voice will say “battery is low”
