Questions about this item

How does the 1.12 in thickness affect whether it fits my door?

The lock body is 1.12 in thick and is designed for standard US doors from 1-3/8 in to 2-1/4 in thick, so it fits most residential doors without modification.

What does the Bluetooth connection actually let me control day to day?

Bluetooth lets you manage codes, view access history, and lock or unlock from the phone app; voice control with Alexa or Google requires a separate gateway.

What hardware is needed to mount the lock on the door?

The box includes a mounting plate, rubber gasket, face plate, back plate, and bolt assembly, so only a screwdriver is required for installation.
