It connected to the app and would light up green showing it was unlocking but it wasn’t unlocking. I tried to calibrate and it still didn’t work.

Does not work? The app appears to work but it will not unlock, it makes you manually put in combo. Not worth it, I am looking to return it. I have synced the lock many times.

Awesome Product!
A friend of mine gave me this lock as a gift. After a quick online setup, I was using my phone to unlock and track activity on the lock.....no more remembering combinations or keeping up with keys for me! I will definitely purchase another one.
