- wmf 9y agoThey have batteries. The Otto apparently has a main battery and backup battery although I don't understand the benefit of such an arrangement. Some smart locks can be operated manually when they run out of power. I once read about an electronic safe that generated power from the user turning the knob; a clever solution.
- extrapickles 9y agoThe US government uses self powering locks where the user turning the dial provides the power for operation. See http://www.kaba-mas.com/kaba-brand/products/906098/x-10.html http://www.kaba-mas.com/kaba-brand/products/906098/x-10.html for an example of one.
