Eneloops would only last about 3 weeks. And disposable last 2 months. This door is used a lot and since it has Zwave and a door open sensor it sends info on every open.
Bonus, since it can handle the lipo AA batteries that put out 1.8v and it gives the motor more oomph I made the battery pack give 7.2v and it never sticks anymore.
This is a garage-door so its not critical access but is used a lot.
Anyone can also buy lockpicks, break a window, kick the door down, my electronic lock isn’t even Bluetooth or use a phone app, so that’s not even a possibility with the majority of them.
Hacking it would require technology and skills not everyone has, there’s easier ways to get in your house than to hack it. If that’s your worry, than you better not use your deadbolt at all. It can be picked in seconds.
Unless you’ve got a reinforced door and frame, a deadbolt isn’t stopping anyone from getting in.
