Plug and play
No need to additional drilling, just replace your mechanical deadbolt with our smart deaedbolt.
then make a smart access without taking the physical keys.
Why US
we hate to find the keys either.
It's upset when you checkout but forget to take the keys, and it's upset when you reach home but without keys. yes, we understand that, so we study the American universal door lock and make this smart deadbolt. It was App enabled, and you could proggramme the passcode and share with your family members. so the annoying about the keys will be finished.
