4 days agoI've tested dozens of smart locks, but I keep this one for its handy keycard feature
The U100 lock features a keypad that requires 6-10 digit passcodes to open. You can add one-time passcodes or ones that only work during a preset period, like for a babysitter every weekday from 3-6 p.m. The app allows you to set up to 75 passwords.
