About 2 months ago the batteries on my Kwikset SmartCode916 for the back door died according to the battery indicator in the Smartthings app and the light on the lock itself. Easy peasy, I changed the batteries. Then I noticed the battery indicator still showed 0% (see image below). The keypad on the lock works, the app is able to unlock and lock the door, but now I see this black dot. The other thing I have noticed is the keypad is very slow to respond to touch. Initially, the keypad was very responsive but now there is a 3-10 second delay before the keypad responds to touch.
Moving on to today. I installed a second Kwikset SmartCode916 on our front door and it works like a charm.
I hope you guys or gals can provide some insight. Thank you in advance!
