Easy45 minHow to Install a Smart Lock on an Exterior Door
A smart lock is the rare upgrade that's both safer and more convenient — keypad or phone entry, no spare key under the mat, and a log of who came and went — and on a standard pre-bored door it's a 45-minute swap with a single screwdriver, no electrician needed. The catch isn't wiring (there usually isn't any); it's buying a lock that actually fits your door and getting the bolt to line up so it never jams. This guide covers the compatibility check that prevents a costly return, the install itself, and the alignment and app setup that make it reliable.
