Usually there is a warning that the battery is dying well ahead of it actually being dead. One that can send notifications will ping your phone with a low battery message. Others have audible warnings. You unlock it and then it starts beeping at you. It keeps doing that until you either change the batteries or it eventually dies. But you have to do a lot of ignoring for it to die on you. Many do have key backups to though.
There are ones like August that only add the smart lock on one side and retain the old hardware on the outside. If the battery runs out you just gotta use your key like a plebian. It warns you ahead of time it’s low though and I’ve never had it fail in the half decade I’ve had it.
Ive always wondered what happens if the battery dies, do you still need to carry a key in case that happens

A few have external terminals to charge them when they die.
I have a 9v battery stashed in a flower pot next to my door for when it happens.
I hope there is a replacement replacement. Life deserves recursion.
Two is one, one is none.
