Tiny Door Smart Lock Options: Space-Smart Security

Your tiny house door is 1-3/8" thick and has zero room for error. Here are the locks that actually fit.

The Challenge

Tiny house doors are thin. Most smart locks assume 1-3/4" thickness. You need solutions that work with less space and won't compromise your door's structural integrity.
