Lockly currently offers 3 different models in 2 different styles: The Secure, the Secure Plus and the Secure Pro models.  All 3 come in either Deadbolt and Latch style.

The Deadbolt style is a smart lock deadbolt only, to be used with your own doorknob/handle. The Latch style is a smart lock with a handle attached. Both styles can be installed on the left or right swing opening doors.

The difference between the Secure and the Secure Plus is that the Secure Plus has a capacitive fingerprint reader that can store up to 99 fingerprints.
