I've tested dozens of smart locks, but I keep this one for its handy keycard feature
Briefly

The Aqara U100 smart lock is currently priced at $135 on Amazon. Installation is straightforward and takes less than 15 minutes. The lock features a keypad for 6-10 digit passcodes and can store up to 75 passwords. A fingerprint sensor allows adding up to 50 fingerprints, boasting a 98.6% recognition rate. While basic Bluetooth connectivity is available, many advanced features require an Aqara Hub for remote operations and automation. NFC support for Apple Home Key is also provided, enhancing convenience.
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.
After setting up my U100 to open with my fingerprint, I've never had issues with it not recognizing my print or failing to respond to it. You can add up to 50 fingerprints in the app, and Aqara says its fingerprint reader features a 98.6% recognition rate.
Once the U100 smart lock was on the door, I set it up with the Aqara app on my iPhone and connected it to an Aqara Hub, which enables remote lock and unlock actions, viewing the current lock status, and configuring password settings.
The entire installation process took less than 15 minutes, showcasing the straightforward mechanism of the deadbolt despite lacking specific instructions in the review unit.
