For renters and owners who need a sliding glass door smart lock that fits the narrow gap without drilling into the glass, here is the setup.

By Jonah Reeves · Home editor · Home desk · Gadget Evaluator Lab

Jonah wouldn't reorder this if… This setup fits the narrow gap between the sliding panel and the frame. It requires no drilling into the glass surface to secure the mechanism.

The chore is securing a patio entry where the gap is too tight for a standard deadbolt and the glass cannot take a drill bit. You need a mechanism that slides into that specific space without altering the pane.

In the product photo, look for the latch assembly that sits within the frame channel. Verify the width of the locking bar matches the gap width shown in the listing image before you proceed.
