Worked fine with 2 phones no problems. Started using a keypad instead on a daily basis with no problems. Tried to use the app to set up a new user for the keypad and discovered the lock and keypad aren't available in the app because I haven't used it for a while. Good job I wasn't outside with a flat keypad battery when I found out about this "Feature"

Keep having stability issues with this. Locked myself out without keys a couple times. Setup is confusing. The custom cylinder parts to size it are incorrectly suggested so that it will never fit together. I managed to set up the lock after a lot of trial and error. Connecting the keypad however remains unsuccessful. It only says "cannot change location settings of the device" this eventhough I did grant the app the location permission. Edit: support says Pixel is not supported, does not help.

I use this app and Smart Lock for my business and it's great. It's user friendly to set up and I can schedule it to lock and unlock my door. The door sensor is very reliable. It would be nice to have a door closer option so that I only get one notification per entry. But I realize for most people that is not a problem. Edited summer 2026 to say that after 5 years I am still very satisfied with the app and the hardware. Would buy again. Highly recommended!
