My Smart Lock: * Stores codes on the device itself and still unlocks with no internet connectivity * Is a physical deadbolt inside that works without power * If the lock itself runs out of battery power from the OUTSIDE, you can "jump" it with a 9-volt battery * Allows me to auto-lock after X period of time, or at night * Allows me to NEVER carry keys, ever. Or ever have to worry about keys. * Allows me to manage multiple, time-boxed codes for people (housekeeper can't get in at midnight) It's pretty damn great, honestly. And I stow a 9-volt in a flower box in case of emergency. (You still need to know the code, obviously.) It's also absolutely pick-proof/bump-proof because it has no key at all. Not even a backup key. It's the Yale x Nest lock and is really really nice.
