It is amazing that none of the smart lock companies have found a way to power the devices without having to replace the batteries all the time. Reading the reviews of smart locks the biggest complaint is that the batteries only last a week or two.

I have the Kwikset Premis, use it multiple times a day every day (to/from work for two people, walking the dog multiple times, etc.), and the last time I changed the batteries was at least 3 months ago. The batteries tend to last 4-6 months between changing. HOWEVER, if you don't install it properly, and the bolt rubs against the sides of the socket AT ALL, you'll be lucky to get a week or two out of the batteries. The first set of batteries only lasted me a week, so I widened out the socket and made absolutely sure the bolt wasn't rubbing. Problem gone. The issue is that any rubbing against the sides means the motor has to work really hard to move the bolt, which obviously burns up the batteries. Frankly, I think it should give a warning tone if the motor is working that hard, although you can hear the difference once you fix your installation. It's good that the motor does what it takes to lock/unlock the door, but a really in-your-face warning that this is killing the batteries would be wise. They might have avoided a lot of bad reviews if they included that feature.
