How to replace batteries
When the battery voltage is insufficient,
and the door cannot be power up from
the outside, you can power the lock
through the Micro USB interface by using
a 5V power bank as an emergency power
supply. After opening the door lock,
please replace the batteries immediately.
In case of a system crash and it's
impossible to open the door from outside,
please press the Reset button and then
release to let it reboot automatically.
The lock is powered by four 1.5V alkaline
batteries. There are two sets of working
power inside the battery cabinet. Eight
batteries can be put in to extend the
battery life and reduce battery replacement
frequency. The battery cabinet is located at
the upper end of the inside escutcheon. By
pushing the cover upwards, you can remove
it and then replace the batteries.
