U-Bolt Smart Lock ($112, originally $199)

Easily the coolest and most innovative part of this lock is the fingerprint unlock feature.

You can also unlock via your smartphone, a numerical code, or, if all else fails, a physical key. Did we mention it's currently on sale for Amazon Prime Day, too? Don't miss out.
